Software Management Operations

This chapter provides information about software management operations on the system.

Understanding the Local File System

The Management Input/Output (MIO/UMIO/MIO2) card provides control and management for the system.

The local file system is made up of files that are stored on one or more of the following:
  • /flash - Flash memory located on the circuit board of the MIO/UMIO/MIO2, is the default storage media for the operating system software image, CLI configuration, and crash log files used by the system.

  • /usb1 - This device is available when a USB memory stick is inserted on the front panel of the active MIO/UMIO/MIO2.

  • /hd-raid - This is the solid state hard disk array supported by the Fabric and Storage Cards (FSCs) and accessed via the active MIO/UMIO/MIO2.

The local file system on the VPC VM is made up of files that are stored on the following:
  • /flash Flash memory allocated as vHDD-1 on the M via the hypervisor is the default storage media for the StarOS image, CLI configuration, and crash log files used by the system.

  • /hd-raid This is the storage space allocated as vHDD-2 on the CF VM by the hypervisor. It is used to store CDRs (Charging Data Records) and UDRs (Usage Data Records).

File Types Used by the Local File System

The following file types can be located in the local file system:
  • Operating System Software Image File: This binary file type is identified by its .bin extension. The file is the operating system that is loaded by the system upon startup or reloading. This is an executable, read-only file that cannot be modified by end users.

  • CLI Configuration File: This file type is identified by its .cfg extension. These are text files that contain CLI commands that work in conjunction with the operating system software image. These files determine services to be provided, hardware and software configurations, and other functions performed by the system. The files are typically created by the end user. You can modify the files both on and off-line and use descriptive long filenames.

  • System File: Only one file identified by a .sys extension is used by the system. The boot.sys file contains system-specific information, which describes how the system locates, and in what priority it loads, file groups (paired .bin and .cfg files) from its boot stack.

  • Abridged Crash Log: The abridged crash log, identified by its crashlog filename, contains summary information about software or hardware failures that occur on the system. This file is located in the /flash/crsh2/ directory on the device. You can view the contents of this file through the CLI, but you cannot modify the file.

Understanding the boot.sys File

The system uses the boot.sys file to store the prioritized boot stack parameters and file groups the system uses during startup. Modify this file only through system CLI commands and not through external means. Boot parameters contain information the system needs to locate the operating system image file, including:
  • bootmode: This setting is typically configured to normal, and identifies how the system starts.

  • network interface configuration: Use these optional boot method settings when you configure the system to obtain its operating system image from an external network server that is using one of the management LAN interfaces on the MIO/UMIO/MIO2 card.

  • boot stack information: The boot stack is made up of prioritized file group entries that designate the operating system image file and the CLI configuration file to load.

When a system is started for the first time, the boot.sys file is configured to use the normal boot mode and load the operating system software image from the /flash directory.

There is no CLI configuration file contained on the local file system. This causes the system to automatically start its CLI-based Quick Setup Wizard upon the first successful boot. Refer to Getting Started for more information on using the Quick Setup Wizard.

Maintaining the Local File System

Use CLI commands to manage and maintain the devices that make up the local file system. Execute all the commands described in this section in the Exec Mode. Unless otherwise specified, you must have security administrator or administrator privileges to execute these commands.

File System Management Commands

Use the commands in this section to manage and organize the local file system.


Important


For complete information on the commands listed below, see the Exec Mode Commands chapter of the Command Line Interface Reference.


Synchronizing the File System

Commands are supported for mirroring the local file systems from the active MIO/UMIO/MIO2 to the standby MIO/UMIO/MIO2 in systems containing two cards. Use these commands to synchronize any or all of the local devices.


Important


Crash log files are not synchronized when these commands are executed.


The following Exec mode command synchronizes the file systems between two MIO/UMIO/MIO2s:
[local]host_name# filesystem synchronize [ /flash | /usb1 | all ] [ checkonly ] [ from card_num | to card_num ] [ -noconfirm ] 

Only filesystems on matching local devices are synchronized. For example, if the active MIO/UMIO/MIO2 contains two local devices (/flash and /usb1) and the standby MIO/UMIO/MIO2 contains only one local device (/flash), then synchronization only occurs on the matching local device (/flash).

The following command synchronizes the file systems on two MIO/UMIO/MIO2 flash devices.
[local]host_name# filsystem synchronize /flash 

Creating Directories

Use the mkdir command to create a new directory on the specific local device. This directory can then be incorporated as part of the path name for any file located in the local file system.

[local]host_name# mkdir { /flash | /usb1 | /hd-raid } /dir_name 

Use the following command to create a directory named configs:

[local]host_name# mkdir /flash/configs 

Renaming Files and Directories

Use the rename command to change the name of a file from its original name to a different name. Remember to use the same file extension, if applicable, to ensure that the file type remains unchanged.

[local]host_name# rename { /flash | /usb1 | /hd-raid } /src_filename { /flash | /usb1 | /hd-raid } /dst_filename [ -noconfirm ]] 

Use the following command to rename a file named iot_test.cfg to iot_accept.cfg on the /flash local device.

[local]host_name# rename /flash/iot_test.cfg /flash/iot_accept.cfg -noconfirm 

Important


Use the rename command only within the same local device. You cannot rename a file and place it onto another local device at the same time. To move a renamed file, you must use the copy command.


Copying Files

These instructions assume that you are at the root prompt for the Exec mode. To save your current configuration, enter the following command:

[local]host_name# copy from_url to_url [-noconfirm] 

To copy a configuration file called system.cfg from a directory that was called cfgfiles to a directory named configs_old, enter the following command:

[local]host_name# copy /flash/cfgfiles/system.cfg /flash/configs_old/system_2011.cfg 

To copy a configuration file called init_config.cfg to the root directory of a TFTP server with a hostname of config_server, enter the following command:

[local]host_name# copy /flash/cfgfiles/init_confg.cfg tftp://config_server/init_config.cfg 

Deleting Files

The delete command removes a designated file from its specified location on the local file system.


Important


This command does not support wildcard entries; each filename must be specified in its entirety.



Caution


Do not delete the boot.sys file. If deleted, the system will not reboot on command and will be rendered inoperable.


[local]host_name# delete { /flash | /usb1 | /hd-raid }/filename [ -noconfirm ] 

The following command deletes a file named test.cfg from the /flash directory.

[local]host_name# delete /flash/test.cfg 

Removing Directories

The rmdir command deletes a current directory on the specific local device. This directory can then be incorporated as part of the path name for any file located in the local file system.


Important


The directory you want to remove (delete) must be empty before executing the rmdir command. If the directory is not empty, the CLI displays a "Directory not empty" message and will not execute.


[local]host_name# rmdir url /dir_name 

The following command deletes an empty directory named configs in the /flash directory.

[local]host_name# rmdir /flash/configs 

Formatting Local Devices

The format command performs a low-level format of a local device. This operation formats the device to use the FAT16 formatting method, which is required for proper read/write functionality with the operating system.


Important


Local devices that have been formatted using other methods such as NTFS or FAT32 may be used to store various operating system, CLI configuration, and crash log files. However, when placing a new local device into the MIO/UMIO/MIO2 for regular use, you should format the device via the system prior to use. This ensures that the proper file allocation table format is used, preventing any possible discrepancies between other formats used with other operating systems.



Caution


The filesystem format command removes all files and information stored on the device.


To format a local device for use by the local file system, enter the following command:

[local]host_name# filesystem format { /flash | /usb1 | /hd-raid } 

Applying Pre-existing CLI Configuration Files

A pre-existing CLI configuration file is any .cfg file created to provide utility functions (such as clearing all statistics during testing) or created off-line using a text editor. There may be pre-existing configuration files stored on the local file system that can be applied to a running system at any time.


Caution


If a configuration file is applied to a system currently running another CLI configuration, any like contexts, services, logical interfaces, physical ports, IP address pools, or other configured items will be overwritten if the same command exists in the configuration file being applied. Take caution to ensure that you are knowledgeable of the contents of the file being applied and understand what the service ramifications are if a currently running command is overwritten. Also note that changes will not be saved automatically.


A CLI configuration file, or script containing CLI commands, can be applied to a running system by entering the following command at the Exec mode prompt:

[local]host_name# configure url [ verbose ] 

url specifies the location of the CLI configuration file to be applied. It may refer to a local or a remote file.

The following command applies a pre-existing CLI configuration file named clearcmds.cfg in the /flash directory.

[local]host_name# configure /flash/clearcmds.cfg 

Viewing Files on the Local File System

This section describes how to view a variety of files.

Viewing the Contents of a Local Device

The contents, usage information, and file system directory structure of any local device can be viewed by entering the following command at the Exec mode prompt:

directory { /flash | /usb1 | /hd-raid } 

Viewing CLI Configuration and boot.sys Files

The contents of CLI configuration and boot.sys files, contained on the local file system, can be viewed off-line (without loading them into the OS) by entering the following command at the Exec mode prompt:

[local]host_name# show file url { /flash | /usb1 | /hd-raid } filename 

Where: url is the path name for the location of the file and filename is the name of the file, including any extension.


Important


Operator and inspector-level users can execute the show file command but cannot execute the directory command.


Validating an Operating System File

The operating system software image file, identified by its .bin extension, is a non-readable, non-editable file that executes on the system, creating its runtime operating system (OS).

It is important to verify a new operating system image file before attempting to load it. To accomplish this, a proprietary checksum algorithm is used to create checksum values for each portion of the application stored within the .bin file during program compilation.

This information can be used to validate the actual file against the checksum values stored within the file during its compilation. If any portion of the image file has become corrupted (for example, the file was truncated or was transferred using ASCII mode instead of binary mode), then this information is reported and the file is deemed unusable.

To validate an operating system software image file, enter the following command at the Exec mode prompt:

[local]host_name# show version { /flash | /usb1 | /hd-raid } /[directory]/filename [all] 
The output of this command displays the following information:
  • Version number

  • Description

  • Date

  • Boot Image

  • Size

  • Flags

  • Platform

If an invalid file is found, the system displays a failure message similar to these:

Failure: Image /flash/image_version.bin CRC check failed! 
Failure: /flash/image_version.bin, has a bad magic number 

Configuring the Boot Stack

The boot stack consists of a prioritized listing of operating system software image-to-CLI configuration file associations. These associations determine the software image and configuration file that gets loaded during system startup or upon a reload/reboot. Though multiple associations can be configured, the system uses the association with the highest priority. If there is an error processing this association (for example, unable to locate one of the files), the system attempts to use the association with the next highest priority.

For VPC-SI and VPC-DI platforms, when the configuration file in the highest configured boot priority is not available (but the image file is), the system boots up with the configuration setup wizard after reloading instead of using the next available boot system priority. Priorities range from 1 to 100, with 1 being the highest priority. The maximum number of boot stack entries that may be configured in the boot.sys file is 10.

Boot stack information is contained in the boot.sys file, described in Understanding the boot.sys File. In addition to boot stack entries, the boot.sys file contains any configuration commands required to define the system boot method as explained in the section that follows.

System Boot Methods

The local-boot method uses software image and configuration files stored locally on the system. On system startup or reboot, the system looks on one of its local devices or /hd-raid for the specific software image and accompanying configuration text file. When using the local-booting method, you only need to configure boot stack parameters.

The system can also be configured to obtain its software image from a specific external network server while it is paired with a configuration text file that resides on the system. When using network booting, you need to configure the following:
  • Boot stack parameters, which define the files to use and in what priority to use them

  • Boot interface and network parameters defining the remote management LAN interface and the methods to use to reach the external network server

  • Network booting delay time and optional name server parameters defining the delay period (in seconds) to allow for network communications to be established, and the IP address of any Domain Name Service (DNS) name server that may be used

Detailed information on how to configure the system to use the network booting method appears in Network Booting Configuration Requirements

Viewing the Current Boot Stack

To view the boot stack entries contained in the boot.sys file run the Exec mode show boot command.


Important


Operator and inspector-level users can execute the show boot command.


The examples below shows the command output for a local booting configuration. Notice that in these examples both the image file (operating system software) and configuration file (CLI commands) are located on the /flash device.


Important


The StarOS image filename format "asr5500-image_number.bin".


Example :
boot system priority 18 \ 
    image /flash/16-1-builds/asr5500-16.1.3.bin \ 
    config /flash/general_config.cfg 
  
boot system priority 19 \  
    image /flash/16-1-builds/asr5500-16.1.1.bin \ 
    config /flash/general_config_3819.cfg 
  
boot system priority 20 \ 
    image /flash/16-1-builds/asr5500-16.1.0.bin \ 
    config /flash/general_config_3665.cfg 

The example below shows the output for a combination network booting and local booting configuration. Notice in this example that the first two boot stack entries (Priorities 18 and 19) load the image file (operating system software) from an external network server using the Trivial File Transfer Protocol (TFTP), while all configuration files are located on the /flash device.

Also notice the boot network interface and boot network configuration commands located at the top of the boot stack. These commands define what remote management LAN interface(s) to use and information about communicating with the external network server that hosts the operating system software image file.
boot networkconfig static ip address mio1 192.168.1.150 netmask 255.255.255.0 
boot delay 15 
boot system priority 18 image tftp://192.168.1.161/tftpboot/image_version.bin \config /flash/general_config.cfg 
boot system priority 19 image tftp://192.168.1.161/tftpboot/image_version.bin \config /flash/general_config.cfg 
boot system priority 20 image /flash/image_version.bin \config /flash/general_config.cfg 
To identify the boot image priority that was loaded at the initial boot time enter:
show boot initial-config 
The example below displays the output:
[local]host_name# show boot initial-config 
Initial (boot time) configuration: 
      image tftp://192.168.1.161/tftpboot/image_version.bin \ 
       config /flash/config_name.cfg 
      priority 1 

Adding a New Boot Stack Entry


Important


Before performing this procedure, verify that there are less than 10 entries in the boot.sys file and that a higher priority entry is available (i.e. that minimally there is no priority 1 entry in the boot stack). Refer to Viewing the Current Boot Stack for more information.


If priority 1 is in use, then you must renumber the existing entry(ies) to ensure that at least that priority is available. The maximum number of boot stack entries that can be contained in the boot.sys file is 10. If there are already 10 entries in the boot stack, you must delete at least one of these entries (typically, the lowest priority) and, if necessary, renumber some or all of the other entries before proceeding. Refer to Deleting a Boot Stack Entry for more information.

This procedure details how to add new boot stack entries to the boot.sys file. Make sure you are at the Exec mode prompt and enter the following commands:
configure 
 boot system priority number image image_url config cfg_url 
The following command creates a new boot stack entry, using a boot priority of 3 .
boot system priority 3 image /flash/image_filename.bin config /flash/config_name.cfg 

Important


Boot stack changes saved to the boot.sys file are not executed until the system is rebooted.


Synchronize the local file systems on the MIO/UMIO/MIO2s with the following command:

Synchronize the local file systems on the CF VMs with the following command:

filesystem synchronize all 

Deleting a Boot Stack Entry

This procedure details how to remove an individual boot stack entry from the boot.sys file. Make sure you are at the Exec mode prompt and enter the following commands:

configure 
   no boot system priority number 

Where number specifies the boot priority used for the boot stack entry. This command removes that specific entry from the boot stack, causing the boot.sys file to be overwritten.

Network Booting Configuration Requirements

Configuring the Boot Interface

Boot interface parameters define the MIO/UMIO/MIO2 management LAN interface that the system will use to communicate with the management network when using the network booting method.

This procedure details how to configure the boot interface for reliable communications with your network server. Make sure you are at the Exec mode prompt.

Procedure

Step 1

Enter the Global Configuration mode by entering the following command:

[local]host_name# configure 
The following prompt appears:
[local]host_name(config)# 

Step 2

Enter the following command:

[local]host_name(config)#boot interface { local-eth1 | local-eth2 } medium { auto | speed { 10 | 100 | 1000 } duplex { full | half } } media { rj45 | sfp } 

For complete information about the above command, see the Global Configuration Mode Commands chapter in the Command Line Interface Reference.

Use port 1 for network booting.

If the speed is manually configured, you must also configure the duplex mode. In addition, you must ensure that the network server configuration supports the speed and duplex configuration.

Network speed for MIO/UMIO/MIO2 is fixed at 1000.

Ethernet networking rules dictate that if a device's interface is configured for auto-negotiation is communicating with a device that is manually configured to support full duplex, the first device will negotiate to the manually configured speed of the second device, but will only communicate in half duplex mode.

The media for MIO/UMIO/MIO2 port 1 is fixed at rj45.

Step 3

Save the configuration as described in the Verifying and Saving Your Configuration chapter.


Configuring the Boot Network

Boot network parameters define the protocols and IP address information for MIO/UMIO/MIO2 interfaces used to reach the external network server that hosts the operating system software image file. To configure boot network parameters, make sure you are at the Exec mode prompt.

Procedure

Step 1

Enter the Global Configuration mode by entering the following command:

[local]host_name(config)#configure 
The following prompt appears:
[local]host_name(config)# 

Step 2

Enter the following command:

[local]host_name(config)# boot networkconfig { dhcp | { { dhcp-static-fallback | static } ip address mio5 ip_address5 [ mio6 ip_address6 ] netmask subnet_mask [ gateway gw_ip_address ] } } 

For complete information about the above command, see the Global Configuration Mode Commands chapter in the Command Line Interface Reference.

The following command configures the boot network to communicate using DHCP, with a static-fallback IP address for MIO/UMIO/MIO2 in slot 5 of 209.165.200.237 and a Class C netmask.
[local]host_name(config)# boot networkconfig dhcp-static-fallback ip address mio5 209.165.200.237 netmask 255.255.255.224 
The next example uses static IP addresses for MIO/UMIO/MIO2 in slot 5, which can access the external network server through a gateway whose IP address is 209.165.200.238.
[local]host_name(config)# boot networkconfig static ip address mio5 209.165.200.237 netmask 255.255.255.224 gateway 209.165.200.238 

Step 3

Save the configuration as described in the Verifying and Saving Your Configuration chapter.


Configuring Boot Network Delay Time

An optional delay period, in seconds, can be configured for systems booting from a network. The purpose of this parameter is to allow time for external devices, such as switches, that use the Spanning Tree Protocol (STP) to determine the network route to a specified IP address.

To configure a boot network delay, enter the following command from the Global Configuration mode prompt.
[local]host_name(config)# boot delay time 

Where time is an integer from 1 to 300 seconds before attempting to contact the external network server. If your network uses STP, a typical delay time of 30 seconds should suffice.


Important


Save your configuration as described in the Verifying and Saving Your Configuration chapter.


Configuring a Boot Nameserver

To configure a boot nameserver address, enter the following command from the Global Configuration mode prompt.
[local]host_name(config)# boot nameserver ip_address 

Where ip_address is the IP address of the DNS server entered in IPv4 dotted-decimal notation.


Important


Save the configuration as described in the Verifying and Saving Your Configuration chapter.


Upgrading the Operating System Software

This section describes how to manually perform the StarOS binary image upgrade procedure.

Prior to initiating the StarOS software upgrade procedure, make sure the conditions described in the Prerequisites section are met.


Caution


Undeploying/redeploying VPC is not supported after the bin upgrade. Deactivating VPC removes the upgraded StarOS bin image.


To upgrade the StarOS software manually:

  1. Obtain VIP Addresses for AutoVNF, CF, ESC and UEM

  2. Identify OS Release Version and Build Number

  3. Download the Software Image from the Support Site

  4. Verify Zookeeper Database

  5. Verify ESC Database

  6. Verify Free Space on the /flash Device

  7. Transfer StarOS Image to /flash

  8. Save the Running Configuration

  9. Synchronize File Systems

  10. Reboot the System

Prerequisites

Prior to performing an upgrade of StarOS software containing CF and SF VNFCs, check if the following prerequisites are met:

  • You’ll need the login credentials and IP address of AutoDeploy, AutoVNF, ESC, UEM, and CF VMs. You should have administrative rights to the OpenStack setup.

  • Verify the OpenStack status. The Ansible output should all pass.

    cd /home/stack/ 
    source stackrc 
    cd /home/stack/ansible/ 
    ansible-playbook -i inventory openstack_verify.yml 
  • Check if the health of AutoVNF/ESC/EM/VNF VM is normal through the UltraM health logs on AutoIT. If any of the VM(s) are not normal, then take necessary actions to rcover the health of the corresponding VM(s).

  • You should have the new StarOS binary image file (for manual upgrade).

  • Ensure that there are no pending transactions between ESC, UEM and CF.

  • Be sure to take a backup of the original StarOS bin file.

Obtain VIP Addresses for AutoVNF, CF, ESC and UEM

This section provides instructions that are applicable only to the upgrade of CF and SF VNFCs.

To collect the VIP addresses for AutoVNF, CF, ESC and UEM VMs:

  1. Log on to the AutoDeploy VM as the default user, ubuntu.

    ssh ubuntu@<ad_vm_address> 
  2. Switch to the root user.

    sudo -i 
  3. Enter the ConfD CLI.

    confd_cli -u admin -C 
  4. Enter the admin user credentials when prompted.

  5. Collect the VIP address of AutoVNF, ESC, UEM and CF VMs.

    show vnfr 

    Example output:

      ip-address       192.168.100.21 

Identify OS Release Version and Build Number

The operating system can be configured to provide services and perform pre-defined functions through commands issued from the CLI.

The operating system software is delivered as a single binary file (.bin file extension) and is loaded as a single instance for the entire system.

  • The image filename is identified by a suffix specifying its platform type and release number. For example, asr5500-release_number. bin. For example, asr5500-16.1.0.bin.

A starfile image must be signed with an REL key before being released. A deployable image will be signed with an REL key having a ".bin.SPA" extension, where "A" identifies the revision level of the signing key. For example, asr5500-20.0.0.bin.SPA. If a signing key becomes compromised, a new key is created and the revision level increments to "B".

Trusted images have been introduced. The difference between a Trusted build and a Normal build is the absence of unsecure programs ftpd, telnet and tcpdump, as well as the addition of a staros.conf file for security options. Trusted images are identifiable by the presence of "_T" in the platform name. For example, asr5500_T-20.0.0.bin.SPA.

To identify the StarOS software version and build information:

  1. Log on to the VNF to be upgraded.

  2. Enter the following Exec mode command in the StarOS command line interface:

    show version 

    Example output:

    Active Software:
    
      Image Version:             21.9.0.69918
    
      Image Build Number:        69918
    
      Image Description:         Deployment_Build
    
      Image Date:                Sun Jul 22 12:08:55 EDT 2018
    
      Boot Image:                /flash/staros.bin
    
      Source Commit ID:          94797337b6c1691541ea0dd86f2f29b0f2c3630c 
  3. Execute the following Exec mode command to display additional information about the StarOS build release.

    show build 

Download the Software Image from the Support Site

This section provides instructions that are applicable only to the upgrade of CF and SF VNFCs.

Access to the Cisco support site and download facility is username and password controlled. You must have an active customer account to access the site and download the StarOS image.

Download the software image to a network location or physical device (USB stick) from which it can be uploaded to the /flash device. Contact your Cisco representative or Cisco TAC for additional information.

For UGP-based VNF, perform the following steps to download the new bin file to AutoVNF or OSPD VM.

  1. Log on to the AutoVNF of the corresponding VNF.

    ssh ubuntu@<ad_vm_address> 

    Command example:

    ssh ubuntu@10.225.202.94 
  2. Create a directory to download the new StarOS qvpc-di binary file to AutoVNF/OSPD.

    cd /home/ubuntu/ 
    mkdir StarOSBinUpgrade 
  3. Download the new StarOS qvpc-di binary file from the Cisco support site and copy the file to the StarOSBinUpgrade directory.

    cd StarOSBinUpgrade 

    Then, use the following command to verify if the directory contains the new bin file.

    ls -lrt /home/ubuntu/StarOSBinUpgrade 

    Example output:

    total 172560
    
    -r--r--r-- 1 ubuntu ubuntu 176698880 Jul 24 23:29 qvpc-di-21.9.0.69932.bin 

Verify Zookeeper Database

This section provides instructions that are applicable only to the upgrade of CF and SF VNFCs.

To verify the zookeeper database:

  1. Log on to the AutoVNF using the floating IP.

    ssh ubuntu@<ad_vm_address> 

    Command example:

    ssh ubuntu@10.225.202.94 
  2. Log on to the UEM VM using the VIP address fetched in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM.

    ssh ubuntu@<vip-addr>

    Command example:

    ssh ubuntu@192.168.100.21 
  3. Become the root user.

    sudo -i 
  4. Collect the UEM orchestration IP address for Zookeeper database connection.

    #ifconfig 
    
    eth0      Link encap:Ethernet  HWaddr fa:16:3e:71:1d:08 
    
                 inet addr:209.165.200.240  Bcast: 209.165.200.255  Mask: 255.255.255.224 
  5. Navigate to the /opt/cisco/usp/packages/zookeeper/<current>/bin directory.

  6. Execute the following script from the command line to access the UEM Zookeeper database.

    zkCli.sh -server ip_addr:port_num 

    For example:

    zkCli.sh -server 209.165.200.240:2181 
  7. Check the zookeeper database and ensure that there are no pending requests between UEM and CF VMs.

    ls /request 

    Example output:

    []
    
    <Ctrl+D to exit Zookeeper shell> 

Verify ESC Database

This section provides instructions that are applicable only to the upgrade of CF and SF VNFCs.

To verify the ESC database:

  1. Log on to the AutoVNF using the floating IP.

    ssh ubuntu@<ad_vm_address> 

    Command example:

    ssh ubuntu@10.225.202.94 
  2. Log on to the ESC VM using the VIP address fetched in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM.

    ssh admin@<vip-addr>

    Command example:

    ssh admin@192.168.100.22 
  3. Check the ESC database to ensure there are no pending transactions.

    sudo /opt/cisco/esc/pgsql/bin/psql -U esc -p 7878 -h localhost -c 'select * from esc_schema.workitem'; 
    
    config_id | request_id | mo_type | config_action | config_state 
    -----------+------------+---------+---------------+--------------
    (0 rows) 
  4. Execute the following command to check the transaction details.

    escadm ip_trans 

    Example output:

    Number of in-progress transaction events = 0 

Verify Free Space on the /flash Device

Verify that there is enough free space on the /flash device to accommodate the new StarOS image file.

To verify the available space on flash directory:

  1. Log on to the CF VM using the previously fetched VIP address in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM.

    ssh ubuntu@<vip-addr>

    Command example:

    ssh ubuntu@192.168.100.38 
  2. Enter the following Exec mode command:

    [local]host_name# directory /flash 
    The following is an example of the type of directory information displayed:
    -rwxrwxr-x    1  root     root         7334 May    5 17:29 asr-config.cfg 
    -rwxrwxr-x    1  root     root         399 Jun    7 18:32 system.cfg

    Note the "Available" blocks in the last line of the display. After displaying the directory information, the CLI returns to root and the following prompt appears:
    [local]host_name# 

Transfer StarOS Image to /flash

For StarOS-based VNF, transfer the new operating system image file to the /flash directory on the MIO/UMIO/MIO2 VPC-DI active CF or VPC-SI using one of the following methods:

  • Copy the file from a network location or local device plugged in into the MIO/UMIO/MIO2 by entering the following command:
    [local]host_name# copy from_url to_url [ -noconfirm ] 
  • Transfer the file to the /flash device using an FTP client with access to the system.


    Important


    Whenever transferring a operating system software image file using the file transfer protocol (FTP), the FTP client must be configured to transfer the file using binary mode. Failure to use binary transfer mode will make the transferred operating system image file unusable. FTP is not supported.
  • Transfer the file to the /flash device using an SFTP client with access to the system.

For UGP-based VNF, copy the new StarOS bin to the active CF by following these steps.

  1. Log on to the AutoVNF or OSPD VM where the new bin file is downloaded.

    ssh ubuntu@<ad_vm_address> 

    Command example:

    ssh ubuntu@10.225.202.94 
  2. Navigate to the directory where the new bin file is downloaded from the Cisco support site.

    cd /home/ubuntu/StarOSBinUpgrade/ && ls -lrt 

    Example output:

    total 172560
    
    -r--r--r-- 1 ubuntu ubuntu 176698880 Jul 24 23:29 qvpc-di-21.9.0.69932.bin 
  3. SFTP to the CF VM.

    For example:

    sftp ubuntu@192.168.100.38 
  4. Navigate to the sftp directory.

    #sftp>pwd 
    Remote working directory: / 
    #sftp>ls 
    hd-raid sftp 
    #sftp>cd sftp 
  5. Upload the new binary file to the sftp directory.

    #sftp>put image_filename.bin 

    Example output:

    #sftp>put qvpc-di-21.9.0.69932.bin 
    Uploading qvpc-di-21.9.0.69932.bin to /.auto/onboard/flash/sftp/qvpc-di-21.9.0.69932.bin
    qvpc-di-21.9.0.69932.bin                             100%  169MB 168.5MB/s   00:01 
  6. Log on to the CF VM using the VIP address fetched in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM.

    ssh ubuntu@<vip-addr>

    Command example:

    ssh ubuntu@192.168.100.38 
  7. Copy the new bin from sftp to flash directory.

    copy /flash/sftp/image_filename.bin /flash/updated.bin 

    Example output:

    #copy /flash/sftp/qvpc-di-21.9.0.69932.bin /flash/updated.bin
    
    **************************************************************
    
    Transferred 176698880 bytes in 2.718 seconds (63486.9 KB/sec) 
  8. Delete the new bin from sftp directory.

    delete /flash/sftp/image_filename.bin 

    Example output:

    delete /flash/sftp/qvpc-di-21.9.0.69932.bin 
    Are you sure? [Yes|No]: yes
    File /flash/sftp/qvpc-di-21.9.0.69932.bin removed 
  9. Verify that the image file was successfully transferred to the /flash device by running the following Exec mode command:

    [local]host_name# directory /flash 

    The image filename should appear in the displayed output.

  10. Execute the following command to verify the build information.

    show version /flash/image_filename.bin 

Saving a Copy of the Current Configuration File

Prior to upgrading to a new software release, you should copy and rename the current configuration file to the /flash device and to an off-chassis location (external memory device or network URL). This renamed copy assures that you will have a fallback, loadable configuration file should a problem be encountered during the upgrade.

Downgrading from Release 20.0

PBKDF2 (Password Based Key Derivation Function - Version 2) is now used to derive a key of given length, based on entered data, salt and number of iterations. Local-user account passwords are hashed using the PBKDF2 method with a randomly generated salt coupled with a large number of iterations to make password storage more secure.

To downgrade the local-user database to use the MD5 hash algorithm, a Security Administrator must run the Exec mode downgrade local-user database command. StarOS prompts for confirmation and requests the Security Administrator to reenter a password. The entered password re-authenticates the user prior to executing the downgrade command. After verification, the password is hashed using the appropriate old/weak encryption algorithm and saved in the database to allow earlier versions of StarOS to authenticate the Security Administrator.

The downgrade process does not convert PBKDF2 hashed passwords to MD5 format. The downgrade process re-reads the database (from the /flash directory), reconstructs the database in the older format, and writes it back to the disk. Since the PBKDF2 hashed passwords cannot be converted to the MD5 hash algorithm, and earlier StarOS releases cannot parse the PBKDF2 encryption algorithm, StarOS suspends all those users encrypted via the PBKDF2 algorithm. Users encrypted via the MD5 algorithm ("Weak Hash" flag) can continue to login with their credentials. After the system comes up with the earlier StarOS release, suspended users can be identified in the output of the show local-user [verbose]command.

To reactivate suspended users a Security Administrator can:
  • Set temporary passwords for suspended users, using the Exec mode password change local-user username command.

  • Reset the suspend flag for users, using the Configuration mode no suspend local-user username command.

Off-line Software Upgrade

An off-line software upgrade can be performed for any system, upgrading from any version of operating system software to any version, regardless of version number. This process is considered off-line because while many of the steps can be performed while the system is currently supporting sessions, the last step of this process requires a reboot to actually apply the software upgrade.

This procedure assumes that you have a CLI session established and are placing the new operating system image file onto the local file system. To begin, make sure you are at the Exec mode prompt:
[local]host_name# 

To perform offline software upgrade:

  1. Configure a Newcall Policy

  2. Configure a Message of the Day Banner

  3. Back up the Current CLI Configuration File

  4. Save the Running Configuration

  5. Create a New Boot Stack Entry

  6. Synchronize File Systems

  7. Reboot the System

Configure a Newcall Policy

Configure a newcall policy from the Exec mode to meet your service requirements. When enabled the policy redirects or rejects new calls in anticipation of the system reload that completes the upgrade process. This reduces the amount of service disruption to subscribers caused by the system reload that completes the upgrade.


Important


Newcall policies are created on a per-service basis. If you have multiple services running on the chassis, you can configure multiple newcall policies.


The syntax for newcall policies is described below:
[local]host_name# newcall policy { asngw-service | asnpc-service | sgsn-service } { all | name service_name } reject 
[local]host_name# newcall policy { fa-service | lns-service | mipv6ha-service } { all | name service_name } reject 
[local]host_name# newcall policy { ha-service | pdsn-service | pdsnclosedrp-service  } { all | name service_name } { redirect target_ip_address [ weight  weight_num ] [ target_ipaddress2 [ weight weight_num ] ... target_ip_address16 [ weight weight_num ] | reject } 
[local]host_name# newcall policy ggsn-service { apn name apn_name | all | name service_name } reject 
[local]host_name# newcall policy hnbgw-service { all | name service_name } reject 
[local]host_name# newcall policy { pcc-af-service | pcc-policy-service } { all | name service_name } reject 
[local]host_name# newcall policy {pcc-af-service | pcc-policy-service } { all | name service_name } reject 
[local]host_name# newcall policy mme-service { all | name service_name } reject 

For complete information about the above commands, see the Exec Mode Commands chapter of the Command Line Interface Reference.

Configure a Message of the Day Banner

Optional: Configure a "Message of the Day" banner informing other management users that the system will be rebooted by entering the following command from the Global Configuration mode prompt.
[local]host_name(config)# banner motd "banner_text" 

banner_text is the message that you would like to be displayed and can be up to 2048 alphanumeric characters. Note that banner_text must begin with and end in quotation marks (" "). For more information in entering CLI banner information, see the CLI Reference. The banner is displayed when an administrative user logs onto the CLI.

Back up the Current CLI Configuration File

Back up the current CLI configuration file by entering the following command:
[local]host_name# copy from_url to_url [ -noconfirm ] 

This creates a mirror-image of the CLI configuration file linked to the operating system defined in the current boot stack entry.

The following command example creates a backup copy of a file called general.cfg located on the /flash device to a file called general_3652.cfg :
[local]host_name# copy /flash/general.cfg /flash/general_3652.cfg 

Save the Running Configuration

Save the currently running, upgraded configuration prior to rebooting the chassis.

To save the boot configuration:

  1. Log on to the VNF using the previously fetched VIP address in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM .

    ssh ubuntu@<vip-addr> 

    Command example:

    ssh ubuntu@192.168.100.38 
  2. Optional. Execute the following command in the Exec mode.

    chassis key value 1234 
    Save config before reload chassis, EVEN IF the same old key value is used.
    Old config scripts will become invalid after reload. 

    Important


    This step is optional, and needed only if the chassis key is not set.


  3. Save the boot configuration in the flash directory.

    save configuration /flash/system.cfg 
    Warning: About to overwrite boot configuration file
    Are you sure? [Yes|No]: yes 

    This will update the boot configuration to use the new bin image.

    Use the following command to check the boot configuration.

    # show boot 
     
    Monday May 21 20:39:57 UTC 2018
    
    boot system priority 8 \
        image /flash/sftp/production.YYYYY.qvpc-di.bin \
        config /flash/sftp/tb5_vnf1_dayN.cfg
    
    boot system priority 9 \
        image /flash/staros.bin \
        config /flash/sftp/tb5_vnf1_dayN.cfg
    
    boot system priority 10 \
        image /flash/staros.bin \
        config /flash/system.cfg
     
  4. Enter the configuration mode to change the boot priority of new StarOS bin file.

    #config 
    #boot system priority 1 image /flash/updated.bin config /flash/system.cfg 
    #end 
  5. Verify the new boot priority.

    #show boot 
    
    boot system priority 1 \
    
        image /flash/updated.bin \
    
        config /flash/system.cfg
    
    boot system priority 10 \
    
        image /flash/staros.bin \
    
        config /flash/system.cfg 
  6. Verify whether the flash directory contains the boot configuration and new bin.

    dir /flash

Create a New Boot Stack Entry

Create a new boot stack entry for the new file group, consisting of the new operating system image file and the currently used CLI configuration file by entering the following Global Configuration command:
[local]host_name(config)# boot system priority number image image_url /flash filename config cfg_url /flash/filename 

Assign the next highest priority to this entry, by using the <N-1> method, wherein you assign a priority number that is one number less than your current highest priority.


Important


Run the Exec mode show boot command to verify that there are less than 10 entries in the boot.sys file and that a higher priority entry is available (minimally there is no priority 1 entry in the boot stack).


If priority 1 is in use, you must renumber the existing entries to ensure that at least that priority is available.

The maximum number of boot stack entries that can be contained in the boot.sys file is 10. If there are already 10 entries in the boot stack, you must delete at least one of these entries (typically, the lowest priority) and, if necessary, renumber some or all of the other entries before proceeding. Use the no boot system priority command to delete a book stack entry.
[local]host_name# configure 
[local]host_name(config)# no boot system priority number 
To add new boot stack entries to the boot.sys file enter the following commands:
[local]host_name# configure 
[local]host_name(config)# boot system priority number image image_url config cfg_url 

For information on using the boot system priority command, refer to the Adding a New Boot Stack Entry .

Reboot the System

To reboot the system (VNF):

  1. Log on to the VNF using the previously fetched VIP address in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM .

    ssh ubuntu@<vip-addr> 

    Command example:

    ssh ubuntu@192.168.100.38 
  2. Enter the following Exec mode command:

    [local]host_name# reload [-noconfirm] 

    As the system reboots, it loads the new operating system software image and its corresponding CLI configuration file using the new boot stack entry configured earlier.

  3. Optional for PDSN: If you are using the IP Pool Sharing Protocol during your upgrade, refer to Configuring IPSP Before the Software Upgrade in the PDSN Administration Guide.

  4. After the reload is complete, log on to the VNF and make sure it is loaded with the intended StarOS version and all the cards have booted up and are in active or stand-by state as expected.

    show version 

    Example output:

    Active Software:

  5. Run the following Exec mode command to display additional information about the running StarOS build release.

    show build 
  6. Optional. Verify the operational state of CF and SF VNFCs.


    Note


    This step is relevant only for the upgrade of CF and SF VNFCs.


    1. Repeat the steps in Verify Zookeeper Database and Verify ESC Database sections.

    2. Log on to the UEM using either the floating IP or from the AutoVNF using the UEM VIP.

      ssh ubuntu@<vip-addr>  

      Command example:

      ssh ubuntu@192.168.100.21 
    3. Become the root user.

      sudo -i 
    4. Collect the UEM orchestration IP address for Zookeeper database connection.

      #ifconfig
      
      eth0      Link encap:Ethernet  HWaddr fa:16:3e:71:1d:08 
      
                inet addr:209.165.200.225  Bcast:209.165.200.255  Mask:255.255.255.224 
    5. Navigate to the /opt/cisco/usp/packages/zookeeper/<current>/bin directory.

    6. Run Zookeeper tool to access the UEM Zookeeper database.

      zkCli.sh -server <vip-addr>:port_num 

      Command example:

      zkCli.sh -server 209.165.200.225:2181 

      Make sure there are no outstanding requests between UEM and CF.

    7. Verify the “state”: “alive” for each of the CFs and SFs using the following commands:

      get /oper/vnfs/vnf_name/vdus/vdu_name/cf1 
      get /oper/vnfs/vnf_name/vdus/vdu_name/cf2 
      get /oper/vnfs/vnf_name/vdus/vdu_name/sf1 
      get /oper/vnfs/vnf_name/vdus/vdu_name/sf2 

      Command examples:

      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-cf1/cf1 
      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-cf1/cf2 
      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-sf1/sf1 
      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-sf1/sf2 
    8. Look for the state Alive in the console output.

      
      zk: localhost:2181(CONNECTED) 2] get /oper/vdus/control-function/BOOT_generic_di-chassis_CF1_1

Save the Running Configuration

Save the currently running, upgraded configuration prior to rebooting the chassis.

To save the boot configuration:

  1. Log on to the VNF using the previously fetched VIP address in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM .

    ssh ubuntu@<vip-addr> 

    Command example:

    ssh ubuntu@192.168.100.38 
  2. Optional. Execute the following command in the Exec mode.

    chassis key value 1234 
    Save config before reload chassis, EVEN IF the same old key value is used.
    Old config scripts will become invalid after reload. 

    Important


    This step is optional, and needed only if the chassis key is not set.


  3. Save the boot configuration in the flash directory.

    save configuration /flash/system.cfg 
    Warning: About to overwrite boot configuration file
    Are you sure? [Yes|No]: yes 

    This will update the boot configuration to use the new bin image.

    Use the following command to check the boot configuration.

    # show boot 
     
    Monday May 21 20:39:57 UTC 2018
    
    boot system priority 8 \
        image /flash/sftp/production.YYYYY.qvpc-di.bin \
        config /flash/sftp/tb5_vnf1_dayN.cfg
    
    boot system priority 9 \
        image /flash/staros.bin \
        config /flash/sftp/tb5_vnf1_dayN.cfg
    
    boot system priority 10 \
        image /flash/staros.bin \
        config /flash/system.cfg
     
  4. Enter the configuration mode to change the boot priority of new StarOS bin file.

    #config 
    #boot system priority 1 image /flash/updated.bin config /flash/system.cfg 
    #end 
  5. Verify the new boot priority.

    #show boot 
    
    boot system priority 1 \
    
        image /flash/updated.bin \
    
        config /flash/system.cfg
    
    boot system priority 10 \
    
        image /flash/staros.bin \
    
        config /flash/system.cfg 
  6. Verify whether the flash directory contains the boot configuration and new bin.

    dir /flash 
    total 320376

Synchronize File Systems

To synchronize the file systems:

  1. Log on to the VNF using the previously fetched VIP address in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM.

  2. Synchronize the local file systems on the management cards by entering the following command:

    [local]host_name# filesystem synchronize all

Reboot the System

To reboot the system (VNF):

  1. Log on to the VNF using the previously fetched VIP address in the Obtain VIP Addresses for AutoVNF, CF, ESC and UEM .

    ssh ubuntu@<vip-addr> 

    Command example:

    ssh ubuntu@192.168.100.38 
  2. Enter the following Exec mode command:

    [local]host_name# reload [-noconfirm] 

    As the system reboots, it loads the new operating system software image and its corresponding CLI configuration file using the new boot stack entry configured earlier.

  3. Optional for PDSN: If you are using the IP Pool Sharing Protocol during your upgrade, refer to Configuring IPSP Before the Software Upgrade in the PDSN Administration Guide.

  4. After the reload is complete, log on to the VNF and make sure it is loaded with the intended StarOS version and all the cards have booted up and are in active or stand-by state as expected.

    show version 

    Example output:

    Active Software:
      Image Version:                  21.9.0.69977
      Image Build Number:             69977

  5. Run the following Exec mode command to display additional information about the running StarOS build release.

    show build 
  6. Optional. Verify the operational state of CF and SF VNFCs.


    Note


    This step is relevant only for the upgrade of CF and SF VNFCs.


    1. Repeat the steps in Verify Zookeeper Database and Verify ESC Database sections.

    2. Log on to the UEM using either the floating IP or from the AutoVNF using the UEM VIP.

      ssh ubuntu@<vip-addr>  

      Command example:

      ssh ubuntu@192.168.100.21 
    3. Become the root user.

      sudo -i 
    4. Collect the UEM orchestration IP address for Zookeeper database connection.

      #ifconfig
      
      eth0      Link encap:Ethernet  HWaddr fa:16:3e:71:1d:08 
      
                inet addr:209.165.200.225  Bcast:209.165.200.255  Mask:255.255.255.224 
    5. Navigate to the /opt/cisco/usp/packages/zookeeper/<current>/bin directory.

    6. Run Zookeeper tool to access the UEM Zookeeper database.

      zkCli.sh -server <vip-addr>:port_num 

      Command example:

      zkCli.sh -server 209.165.200.225:2181 

      Make sure there are no outstanding requests between UEM and CF.

    7. Verify the “state”: “alive” for each of the CFs and SFs using the following commands:

      get /oper/vnfs/vnf_name/vdus/vdu_name/cf1 
      get /oper/vnfs/vnf_name/vdus/vdu_name/cf2 
      get /oper/vnfs/vnf_name/vdus/vdu_name/sf1 
      get /oper/vnfs/vnf_name/vdus/vdu_name/sf2 

      Command examples:

      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-cf1/cf1 
      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-cf1/cf2 
      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-sf1/sf1 
      get /oper/vnfs/tb1-autovnf1_vpc-vpc-core/vdus/vdu-sf1/sf2 
    8. Look for the state Alive in the console output.

      
      zk: localhost:2181(CONNECTED) 2] get /oper/vdus/control-function/BOOT_generic_di-chassis_CF1_1

Restoring the Previous Software Image

If for some reason you need to undo the upgrade, perform the upgrade again except:

  • Specify the locations of the upgrade software image and configuration files.

then

  • Specify the locations of the original software image and configuration files.

Upgrading ICSR Chassis

The procedure for upgrading primary and backup ICSR chassis is described in Interchassis Session Recovery. Essentially the procedure requires upgrading the primary and standby chassis using the off-line method while each is in standby mode.

Performing Dynamic Software Updates

StarOS allows the runtime loading of plugins. All StarOS builds include a "default" baseline plugin.

This feature is currently used to dynamically update the detection logic used to filter P2P applications via the Application Detection and Control (ADC) feature.

Patching is the process used to install a plugin as an incremental update to a StarOS release. One plugin can be provided to multiple, compatible, concurrent product releases. A plugin is distributed in the form of a compressed distribution kit via the internet or by other means (USB stick, CD, etc.).

A plugin is a functional software entity that provides incremental updates to a pre-existing StarOS software component. Plugins have the characteristic of being dynamically loadable at runtime and do not require a system restart. A plugin has a name and one or more versions. All plugin names are known to the system at product release.

For complete information on the Dynamic Software Update process, refer to the ADC Administration Guide.

Managing License Keys

License keys define capacity limits (number of allowed subscriber sessions) and available features on your system. Adding new license keys allows you to increase capacity and add new features as your subscriber base grows.

New System License Keys

New systems are delivered with no license keys installed. In most cases, you receive the license key in electronic format (usually through e-mail).

When a system boots with no license key installed a default set of restricted session use and feature licenses is installed. The following Exec Mode command lists the license information:
[local]host_name# show license information 

Important


With no license key installed, the session use licenses for PDSN, HA, GGSN, and L2TP LNS are limited to 10,000 sessions.


The license keys on the ASR 5500 are stored in EEPROM on the chassis midplane. Both MIO/UMIO/MIO2s access this EEPROM when booting.

Session Use and Feature Use Licenses

Session use and feature use licenses are software mechanisms that provide session limit controls and enable special features within the system. These electronic licenses are stored in the system's configuration file that is loaded as part of the system software each time the system is powered on or restarted.
  • Session use licenses limit the number of concurrent sessions that a system is capable of supporting per service type and are acquired on an as-needed basis. This allows carriers to pay only for what they are using and easily increase capacity as their subscriber base grows.

  • Feature use licenses enable specific features/functionality within the system and are distributed based on the total number of sessions supported by the system.

Installing New License Keys

Use the instructions below to install a new license key.

Cutting and Pasting the Key

If you have a copy of the license, use the following configuration to cut and paste just the license key part:

Procedure

Step 1

From the Exec mode, enter the following:

configure 
   license key license 
   exit 
license is the license key string. The license can be an alphanumeric string of 1 through 1023 characters that is case sensitive. Copy the license key as shown in the example below, including the "\ (double-quote slash). Please note: this is not a functional license.
"\ 
VER=1|C1M=000-0000-00|C1S=03290231803|C2M=11-1111-11-1|C2S=\ 
STCB21M82003R80411A4|DOI=0000000000|DOE=00000000|ISS=1|NUM=13459|0000000000000| 
LSP=000000|LSH=000000|LSG=500000|LSL=500000\|FIS=Y|FR4=Y|FPP=Y|FCS=Y|FTC=Y|FMG=Y| 
FCR=Y|FSR=Y|FPM=Y|FID=Y|SIG=MCwCF\Esnq6Bs/ 
XdmyfLe7rHcD4sVP2bzAhQ3IeHDoyyd6388jHsHD99sg36SG267gshssja77 
end 

Step 2

Verify that the license key just entered was accepted by entering the following command at the Exec mode prompt:

[local]host_name# show license key 
The new license key should be displayed. If it is not, return to the Global configuration mode and re-enter the key using the license key command.

Important

 
An invalid license will not be accepted. A Failure error will appear in the output of the license key command when you attempt to configure an invalid license key. If you use the -force option to install an invalid license key, the license will be placed into a 30-day grace period. StarOS will generate daily syslog error messages and SNMP traps during the grace period. The output of the show license information command will indicate "License State" as "Not Valid".

Step 3

Verify that the license key enabled the correct functionality by entering the following command:

[local]host_name# show license information   
All license keys and the new session capacity or functionality enabled should be listed. If the functionality or session capacity enabled by the new key is incorrect, please contact your service representative.

Step 4

Save your configuration as described in the Verifying and Saving Your Configuration chapter.

Caution

 

Failure to save the new license key configuration in the current CLI configuration file will result in the loss of any of the new features enabled by the license key once the system is reloaded.


Adding License Keys to Configuration Files

License keys can be added to a new or existing configuration file.


Important


License key information is maintained as part of the CLI configuration. Each time a key is installed or updated, you must re-save the configuration file.


Procedure

Step 1

Open the configuration file to which the new license key commands are to be copied.

Step 2

Copy the license as shown in the example, including the "\ (double-quote slash). Please note: this is not a functional license.

"\ 
VER=1|C1M=000-0000-00|C1S=03290231803|C2M=11-1111-11-1|C2S=\STCB21M82003R80411A4| 
DOI=0000000000|DOE=00000000|ISS=1|NUM=13459|0000000000000|LSP=000000|LSH=000000|

SIG=MCwCF\Esnq6Bs/XdmyfLe7rHcD4sVP2bzAhQ3IeHDoyyd6388jHsHD99sg36SG267gshssja77
end 

Step 3

Paste the license key into the configuration

Important

 

Paste the license key information at the beginning of the configuration file to ensure the system has the expected capacity and features before it configures contexts.

Step 4

Save your configuration as described in the Verifying and Saving Your Configuration chapter.


License Expiration Behavior

When a license expires, there is a built-in grace period of 30 days that allows normal use of the licensed session use and feature use licenses. This allows you to obtain a new license without any interruption of service.

The following Exec mode command lists the license information including the date the grace period is set to expire:
show license information   

Requesting License Keys

License keys for the system can be obtained through your Cisco account representative. Specific information is required before a license key may be generated:

  • Sales Order or Purchase Order information

  • Desired session capacity

  • Desired functionality

  • Midplane (chassis) serial number

To obtain the ASR 5500 chassis serial number, at the Exec mode prompt enter the show card hardware 5 command. Look under the "MEC" heading for the "UDI Serial Number" as shown in the example below:
MEC: 
  Description         : MEC 
  Cisco Part Number   : 73-14501-01 A0 
  UDI Serial Number   : FLM154300D8 
  UDI Product ID      : ASR55-MEC 
  UDI Version ID      : V01  

The ICSR license key for Active and Standby chassis are uniquely coded to each chassis. Two separate license keys are required.

Viewing License Information

To see the license detail, enter the following command from the Exec mode:

[local]host_name# show license information [ full | key [ full ] ]  

Deleting a License Key

Use the procedure below to delete the session and feature use license key from a configuration. You must be a security administrator or administrator.

configure 
   no license key 
   exit 
show license key 

The output of this command should display: "No license key installed ".

Management Card Replacement and License Keys

License keys are stored on a midplane EEPROM in the ASR 5500 chassis. The MIO/UMIO/MIO2s share these license keys. There is no need to swap memory cards into replacement MIO/UMIO/MIO2s.

Managing Local-User Administrative Accounts

Unlike context-level administrative accounts which are configured via a configuration file, information for local-user administrative accounts is maintained in a separate file in flash memory and managed through the software's Shared Configuration Task (SCT). Because local-user accounts were designed to be compliant with ANSI T1.276-2003, the system provides a number of mechanisms for managing these types of administrative user accounts.

For additional information, see Disable AAA-based Authentication for Console and Limit local-user Login on Console/vty Lines.

Configuring Local-User Password Properties

Local-user account password properties are configured globally and apply to all local-user accounts. The system supports the configuration of the following password properties:

  • Complexity: Password complexity can be forced to be compliant with ANSI T1.276-2003.

  • History length: How many previous password versions should be tracked by the system.

  • Maximum age: How long a user can use the same password.

  • Minimum number of characters to change: How many characters must be changed in the password during a reset.

  • Minimum change interval: How often a user can change their password.

  • Minimum length: The minimum number of characters a valid password must contain.

  • Expiry warning: Password expiry warning interval in days.

  • Auto-generate: Automatically generates password with option to specify length of password.

Refer to the local-user password command in the Global Configuration Mode Commands chapter of the Command Line Interface Reference for details on each of the above parameters.

Configuring Local-User Account Management Properties

Local-user account management includes configuring account lockouts and user suspensions.

Local-User Account Lockouts

Local-user accounts can be administratively locked for the following reasons:
  • Login failures: The configured maximum login failure threshold has been reached. Refer to the local-user max-failed-logins command in the Global Configuration Mode Commands chapter of the Command Line Interface Reference for details

  • Password Aging: The configured maximum password age has been reached. Refer to the local-user password command in the Global Configuration Mode Commands chapter of the Command Line Interface Reference for details.

Accounts that are locked out are inaccessible to the user until either the configured lockout time is reached (refer to the local-user lockout-time command in the Global Configuration Mode Commands chapter of the Command Line Interface Reference) or a security administrator clears the lockout (refer to the clear local-user command in the Exec Mode Commands chapter of the Command Line Interface Reference).


Important


Local-user administrative user accounts could be configured to enforce or reject lockouts. Refer to the local-user username command in the Global Configuration Mode Commands chapter of the Command Line Interface Reference for details.


Local-User Account Suspensions

Local-user accounts can be suspended as follows:

configure 
   suspend local-user name 
A suspension can be removed by entering:
configure 
   no suspend local-user name 

Changing Local-User Passwords

Local-user administrative users can change their passwords using the password change command in the Exec mode. Users are prompted to enter their current and new passwords.

Security administrators can reset passwords for local-users by entering the following command from the root prompt in the Exec mode:
[local]host_name# password change username name 

name is the name of the local-user account for which the password is to be changed. When a security administrator resets a local-user's password, the system prompts the user to change their password the next time they login.

All new passwords must adhere to the password properties configured for the system.
