Start Up Configuration of the Cisco cBR Router

This document describes the basic start up configuration tasks that must be completed on a Cisco cBR Series Converged Broadband Router.

Prerequisites for Configuring the Cisco CMTS

Complete these prerequisite steps before you power on and configure the Cisco CMTS:

  • Ensure that your network supports reliable broadband data transmission. Your plant must be swept, balanced, and certified based on National Television Standards Committee (NTSC) or appropriate international cable plant recommendations. Ensure your plant meets all Data-over-Cable Service Interface Specifications (DOCSIS) downstream and upstream radio frequency (RF) requirements.
  • Ensure that your Cisco CMTS is installed according to the instructions in the hardware installation guide available on Cisco.com.
  • Ensure that all other required headend or distribution hub routing and network interface equipment is installed, configured, and operational (based on the supported services). This includes:
    • All routers
    • Servers ( Dynamic Host Configuration Protocol (DHCP) servers, Trivial File Transfer Protocol ( TFTP) servers, and time-of-day (ToD) servers)
    • Network management systems
    • Other configuration or billing systems
  • Ensure that DHCP and DOCSIS configuration files have been created and pushed to appropriate servers so that each CM, when initialized, can:
    • Transmit a DHCP request
    • Receive an IP address
    • Obtain TFTP and ToD server addresses
    • Download a DOCSIS configuration file (or updated software image if using Cisco uBR924 cable access routers or Cisco uBR910 cable data service units (DSUs) in your network)
  • Ensure that customer premises equipment (CPE)—CMs or set-top boxes (STBs), PCs, telephones, or facsimile machines—meet requirements for your network and service offerings.
  • Be familiar with your channel plan to assign appropriate frequencies. Outline your strategies for setting up bundling, if applicable to your headend or distribution hub. As appropriate, obtain:
    • Passwords
    • IP addresses
    • Subnet masks
    • Device names
After these prerequisites are met, you are ready to configure the Cisco CMTS. This includes, at a minimum:
  • Configuring a host name and password for the Cisco CMTS
  • Configuring the CMTS to support IP over the cable plant and network backbone

Note
If you plan to use service-class-based provisioning, the service classes must be configured at the CMTS before CMs attempt to make a connection.

Note

Do not configure the logging event link-status command during system initialization. It may take long time or even stop the standby SUP from booting up.

Booting and Logging onto the Cisco CMTS

The Cisco CMTS is administered using the Cisco command interpreter, called the EXEC. You must boot and log in to the router before you can enter an EXEC command.

Procedure

Step 1

Connect to the console port on the Supervisor PIC and the Supervisor card.

Step 2

Establish a terminal session. You can open terminal application (Hyper Terminal) on a PC as follows:

  1. Connect using: Direct to Com 1

  2. Set bits per second:9600

  3. Set data bits: 8

  4. Set parity: none

  5. Set stop bit: 1

  6. Set flow control: none

    Type no when the following message is displayed: 
    
Would you like to enter the initial dialog?[yes]: no

Setting Environment Variables

No Environment variables are required to boot the Cisco IOS-XE image.

There are variables set by default. The ROMMON command set displays the default variables. 


rommon  > set
PS1=rommon ! > 
?=0
rommon  >

To set a variable, the format is VARIABLE="value".

Theset command displays the new variable and the sync command saves the variable to NVRAM.


Note

If the variable value has a space in between, specify the value within quotes. 


rommon  > set
PS1=rommon ! > 
?=0
rommon  > IP_ADDRESS=1.2.3.4

Gigabit Ethernet Management Interface Overview

The purpose of this interface is to allow users to perform management tasks on the router; it is basically an interface that should not and often cannot forward network traffic but can otherwise access the router, often via Telnet and SSH, and perform most management tasks on the router.

The following aspects of the Management Ethernet interface should be noted:

  • Each SUP has a Management Ethernet interface, but only the active SUP has an accessible Management Ethernet interface (the standby SUP can be accessed using the console port, however).

  • IPv4, IPv6, and ARP are the only routed protocols supported for the interface.

  • The interface provides a method of access to the router even when some software processes are down.

  • The Ethernet Management Interface cannot be used as a Lawful Intercept MD source interface.

  • The Management Ethernet interface is part of its own VRF.

Gigabit Ethernet Port Numbering

The Gigabit Ethernet Management port is always GigabitEthernet0.

In a dual SUP configuration, the Management Ethernet interface on the active SUP will always be Gigabit Ethernet 0, while the Management Ethernet interface on the standby SUP will not be accessible using the Cisco IOS-XE CLI in the same telnet session. The standby SUP can be telnetted to through the console port, however.

The port can be accessed in configuration mode like any other port on the Cisco cBR Series Routers: 


Router#configure terminal 
Enter configuration commands, one per line. End with CNTL/Z. 
Router(config)#interface gigabitethernet0 
Router(config-if)#

IP Address Handling in ROMMON and the Management Ethernet Port

Assuming the IOS-XE process has not begun running on the Cisco cBR Series Router, the IP address that was set in ROMMON acts as the IP address of the Management Ethernet interface. In cases where the IOS-XE process is running and has taken control of the Management Ethernet interface, the IP address specified when configuring the Gigabit Ethernet 0 interface in the IOS-XE CLI becomes the IP address of the Management Ethernet interface. The ROMMON-defined IP address is only used as the interface address when the IOS-XE process is inactive.

For this reason, the IP addresses specified in ROMMON and in the IOS-XE CLI can be identical and the Management Ethernet interface will function properly in single SUP configurations.

In dual SUP configurations, however, users should never configure the IP address in the ROMMON on either SUP0 or SUP1 to match each other or the IP address as defined by the IOS-XE CLI. Configuring matching IP addresses introduces the possibility for an active and standby Management Ethernet interface having the same IP address with different MAC addresses, which will lead to unpredictable traffic treatment.

Gigabit Ethernet Management Interface VRF

Placing the management Ethernet interface in its own VRF has the following effects on the Management Ethernet interface:

  • Many features must be configured or used inside the VRF, so the CLI may be different for certain Management Ethernet functions on the Cisco cBR Series Routers than on Management Ethernet interfaces on other routers.

  • The VRF prevents route leakage and avoids unnecessary traffic through the management port.

The Management Ethernet interface VRF supports both IPv4 and IPv6 address families.

Common Ethernet Management Tasks

Because users can perform most tasks on a router through the Management Ethernet interface, many tasks can be done by accessing the router through the Management Ethernet interface.

This section documents tasks that might be common or slightly tricky on the Cisco cBR Series Routers. It is not intended as a comprehensive list of all tasks that can be done using the Management Ethernet interface.

Viewing the VRF Configuration

The VRF configuration for the Management Ethernet interface is viewable using the show running-config vrf command.

This example shows the default VRF configuration: 


Router# show running-config vrf 
Building configuration... 
  
Current configuration : 351 bytes 
vrf definition Mgmt-intf 
! 
address-family ipv4 
exit-address-family 
! 
address-family ipv6 
exit-address-family 
! 
(some output removed for brevity)

Setting a Default Route in the Management Ethernet Interface VRF

To set a default route in the Management Ethernet Interface VRF, use the ip route vrf Mgmt-intf 0.0.0.0 0.0.0.0 next-hop-IP-address command.

Setting the Management Ethernet IP Address

The IP address of the Management Ethernet port is set like the IP address on any other interface.

Below are two simple examples of configuring an IPv4 address and an IPv6 address on the Management Ethernet interface.

IPv4 Example 


Router(config)# interface GigabitEthernet 0 
Router(config-if)# ip address A.B.C.D A.B.C.D

IPv6 Example 


Router(config)# interface GigabitEthernet 0 
Router(config-if)# ipv6 address X:X:X:X::X /prefix-length

Telnetting over the Management Ethernet Interface

Telnetting can be done through the VRF using the Management Ethernet interface.

In the following example, the router telnets to 172.17.1.1 through the Management Ethernet interface VRF: 

Router# telnet 172.17.1.1 /vrf Mgmt-intf

Pinging over the Management Ethernet Interface

Pinging other interfaces using the Management Ethernet interface is done through the VRF.

In the following example, the router pings the interface with the IP address of 172.17.1.1 through the Management Ethernet interface: 


Router# ping vrf Mgmt-intf 172.17.1.1 
Type escape sequence to abort. 
Sending 5, 100-byte ICMP Echos to 172.17.1.1, timeout is 2 seconds: 
.!!!! 
Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/1 ms

Copy Using TFTP or FTP

To copy a file using TFTP through the Management Ethernet interface, the ip tftp source-interface GigabitEthernet 0 command must be entered before entering the copy tftp command because the copy tftp command has no option of specifying a VRF name.

Similarly, to copy a file using FTP through the Management Ethernet interface, the ip ftp source-interface GigabitEthernet 0 command must be entered before entering the copy ftp command because the copy ftp command has no option of specifying a VRF name.

TFTP Example 

Router(config)# ip tftp source-interface gigabitethernet 0

FTP Example 

Router(config)# ip ftp source-interface gigabitethernet 0

NTP Server

To allow the software clock to be synchronized by a Network Time Protocol (NTP) time server over the Management Ethernet interface, enter the ntp server vrf Mgmt-intf command and specify the IP address of the device providing the update.

The following CLI provides an example of this procedure. 

Router(config)# ntp server vrf Mgmt-intf 172.17.1.1

SYSLOG Server

To specify the Management Ethernet interface as the source IP or IPv6 address for logging purposes, enter the logging host ip-address vrf Mgmt-intf command.

The following CLI provides an example of this procedure. 

Router(config)# logging host ip-address vrf Mgmt-intf

SNMP-Related Services

To specify the Management Ethernet interface as the source of all SNMP trap messages, enter the snmp-server source-interface traps gigabitEthernet 0 command.

The following CLI provides an example of this procedure: 

Router(config)# snmp-server source-interface traps gigabitEthernet 0

Domain Name Assignment

The IP domain name assignment for the Management Ethernet interface is done through the VRF.

To define the default domain name as the Management Ethernet VRF interface, enter the ip domain-name vrf Mgmt-intf domain command. 

 Router(config)# ip domain-name vrf Mgmt-intf cisco.com

DNS service

To specify the Management Ethernet interface VRF as a name server, enter the ip name-server vrf Mgmt-intf IPv4/IPv6 address command.

RADIUS or TACACS+ Server

To group the Management VRF as part of a AAA server group, enter the ip vrf forward Mgmt-intf command when configuring the AAA server group.

The same concept is true for configuring a TACACS+ server group. To group the Management VRF as part of a TACACS+ server group, enter the ip vrf forwarding Mgmt-intf command when configuring the TACACS+ server group.

RADIUS Server Group Configuration 

 
Router(config)# aaa group server radius hello
Router(config-sg-radius)# ip vrf forwarding Mgmt-intf

TACACS+ Server Group Configuration 


Router(config)# aaa group server tacacs+ hello
Router(config-sg-tacacs+)# ip vrf forwarding Mgmt-intf

VTY lines with ACL

To ensure an access control list (ACL) is attached to vty lines that are and are not using VRF, use the vrf-also option when attaching the ACL to the vty lines. 


Router(config)# line vty 0 4
Router(config-line)#access-class 90 in vrf-also

Connecting the New Router to the Network

Connect the new router to the network using a n Ethernet interface. After the router successfully resolves its host name, new router sends a TFTP broadcast requesting the file name-confg or name.cfg. The router name must be in all lowercase, even if the true host name is not. The file is downloaded to the new router, where the configuration commands take effect immediately. If the configuration file is complete, the new router should be fully operational.

To save the complete configuration to NVRAM, use the following commands in privileged EXEC mode:

Procedure

  Command or Action Purpose

Step 1

enable password

Enters privileged mode on the new router.

Step 2

copy running-config startup-config

Saves the information from the name-config file into your startup configuration. On most platforms, this step saves the configuration to NVRAM.

Note

 

Verify that the existing and new routers (or access servers) are connected before entering the copy running-config startup-config EXEC command to save configuration changes. Use the ping EXEC command to verify connectivity. If an incorrect configuration file is downloaded, the new router will load NVRAM configuration information before it can enter AutoInstall mode.

If the configuration file is a minimal configuration file, the new router comes up, but with only one interface operational. Use the following commands to connect to the new router and configure it.

Step 3

telnet existing

Establishes a Telnet connection to the existing router.

Step 4

telnet newrouter

From the existing router, establishes a Telnet connection to the new router.

Step 5

enable password

Enters privileged EXEC mode.

Step 6

setup

Enters setup mode to configure the new router.

Setting Password Protection on the Cisco CMTS


Note
For security purposes, the EXEC has two levels of access to commands: user EXEC mode and privileged EXEC mode. The commands available at the user level are a subset of those available at the privileged level.

Tip
Because many privileged-level EXEC commands are used to set operating parameters, password-protect these commands to prevent unauthorized use.

Note
An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters. An enable password can contain any number of uppercase and lowercase alphanumeric characters. A number cannot be the first character. Spaces are valid password characters; for example, “two words” is a valid password. Leading spaces are ignored. Trailing spaces are recognized. Alphanumeric characters are recognized as uppercase or lowercase.

Passwords should be different for maximum security. If you enter the same password for both during the setup script, the system accepts it, but you receive a warning message indicating that you should enter a different password.

At the EXEC prompt, enter one of the following two commands to set password protection:

  • enable secret password —a very secure encrypted password.

  • enable —is a less secure and nonencrypted password.

To gain access to privileged-level commands, enter the desired password.

Recovering Lost Password on the Cisco CMTS

Complete the following steps to recover or replace a lost enable, enable secret, or console login password:

Procedure

Step 1

Attach an ASCII terminal to the console port on your Cisco CMTS.

Step 2

Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 1 stop bits.

Step 3

If you can log in to the router as a nonprivileged user, enter the show version command to display the existing configuration register value. Note the value for later use. If you cannot log in to the router at all, continue with the next step.

Step 4

Press the Break key or send a Break from the console terminal.

  • If Break is enabled, the router enters the ROM monitor, indicated by the ROM monitor prompt (rommon n>), where n is the number of the command line. Proceed to configuring the register.
  • If Break is disabled, power cycle the router (turn the router off or unplug the power cord, and then restore power). Within 60 seconds of restoring the power to the router, press the Break key or send a Break. This action causes the router to enter the ROM monitor and display the ROM monitor prompt (rommon 1>).

Step 5

To set the configuration register on a Cisco CMTS, use the configuration register utility by entering the confreg command at the ROM monitor prompt as follows: 

rommon 1> confreg

Answer yes to the enable ignore system config info? prompt and note the current configuration register settings.

Step 6

Initialize the router by entering the reset command as follows: 

rommon 2> reset

The router initializes, the configuration register is set to 0x142, the router boots the system image from Flash memory and enters the System Configuration dialog (setup), as follows: 


--- System Configuration Dialog --

Step 7

Enter no in response to the System Configuration dialog prompts until the following message appears: 


Press RETURN to get started!

Step 8

Press Return. The user EXEC prompt appears as follows: 


Router>

Step 9

Enter the enable command to enter privileged EXEC mode.

Step 10

Enter the show startup-config command to display the passwords in the configuration file as follows: 


Router# show startup-config

Step 11

Scan the configuration file display looking for the passwords; the enable passwords are usually near the beginning of the file, and the console login or user EXEC password is near the end. The passwords displayed will look something like this: 


enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei
enable password 23skiddoo
.
.
line con 0
 password onramp

Note

 
The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console passwords can be encrypted text or clear text.

Proceed to the next step to replace an enable secret, console login, or enable password. If there is no enable secret password, note the enable and console login passwords if they are not encrypted and proceed to set the configuration register to the original value.

Caution

 
Do not perform the next step unless you have determined that you must change or replace the enable, enable secret, or console login passwords. Failure to follow the steps as presented here could cause your router configuration to be erased.

Step 12

(Optional) Enter the configure memory command to load the startup configuration file into running memory. This action allows you to modify or replace passwords in the configuration. 


Router# configure memory

Step 13

Enter the configure terminal command for configuration mode: 


Router# configure terminal

Step 14

To change all three passwords, enter the following commands: 


Router(config)# enable secret newpassword1

Router(config)# enable password newpassword2
Router(config)# line con 0

Router(config)# password newpassword3

Change only the passwords necessary for your configuration. You can remove individual passwords by using the no form of the previous commands. For example, entering the no enable secret command removes the enable secret password.

Step 15

You must configure all interfaces to not be administratively shut down as follows: 


Router(config)# interface gigabitethernet 0

Router(config)# no shutdown

Enter the equivalent commands for all interfaces that were originally configured. If you omit this step, all interfaces are administratively shut down and unavailable when the router is restarted.

Step 16

Use the config-register command to set the configuration register to the original value noted earlier.

Step 17

Press Ctrl-Z or type end to exit configuration mode: 



Router(config)# end

Caution

 
Do not perform the next step unless you have changed or replaced a password. If you skipped changing or replacing the enable, enable secret, or console login passwords previously, then proceed now to reload. Failure to observe this sequence causes the system to erase your router configuration file.

Step 18

Enter the copy running-config startup-config command to save the new configuration to nonvolatile memory: 


Router# copy running-config startup-config

Step 19

Enter the reload command to reboot the router: 



Router# reload

Step 20

Log in to the router with the new or recovered passwords.

Saving Your Configuration Settings

To store the configuration or changes to your startup configuration in NVRAM, enter the copy running-config startup-config command at the Router# prompt.

This command saves the configuration settings you set using configuration mode, the Setup facility, or AutoInstall.


Note
If you do not save your settings, your configuration will be lost the next time you reload the router.

Example


Router# copy running-config startup-config

Reviewing Your Settings and Configurations

  • To view the current configuration of a Cisco CMTS, run the show running-config command at the command-line interface (CLI) prompt in EXEC mode or privileged EXEC mode.
  • To review changes you make to the configuration, use the EXEC show startup-config command to display the information stored in NVRAM.
