Upgrading the Cisco cBR-8 Router System to Cisco IOS XE Bengaluru 17.6.1z

Note

Starting from Cisco IOS XE Bengaluru 17.6.1a, CBR-CCAP-LC-G2-R can only protect CBR-CCAP-LC-G2-R for linecard HA.

Note

If you are using TACACS authentication, the TACACS configuration will be automatically updated to the new version after upgrading to Cisco IOS XE Bengaluru 17.6.1z. This is a fix to CSCvu62273 and you do not need to take any action regarding the TACACS configuration in the cBR-8 prior to the upgrade.

This section contains the upgrade procedures for the Cisco cBR-8 Router System.

By default, telnet is disabled on Cisco cBR-8. If you are going to use telnet to access the device, make sure the value of line vty transport is correct and save the configuration in order to enable telnet.

Router# show run | begin line vty
line vty 0 4

Note

If the user wants to upgrade Supervisor CPLD to version 19071712 and 190717E1, the chassis must be running with Cisco IOS XE Gibraltar 16.12.1w or later releases.

Note

Cisco recommends that operators upgrade their On-Premise SSM Satellite software versions to v7.x or later releases, to ensure the compatibility with cBR-8.

Verify max-carrier value

Currently in Remote PHY system, max-carrier value can be configured in the downstream controller profile as well as in RPD configuration for Cisco Remote PHY Shelf 300/600/7200. This may lead to inconsistent max-carrier value configurations.

Starting from Cisco IOS XE Gibraltar 16.10.1f, max-carrier value configured in the cable rpd mode is removed and RPD will use the max-carrier value configured in the controller-profile mode for the power calculation.

Before upgrading to Cisco IOS XE Gibraltar 16.10.1f or later releases, verify if the max-carrier values configured in the RPD shelf configuration and downstream controller profile(s) associated to RPD downstream port are the same. If they are different, update the cBR-8 configuration prior to upgrade.

Below is an example of correct configuration before upgrade.

cable downstream controller-profile 1
 max-carrier 128
 max-ofdm-spectrum 384000000
 rf-chan 0 3
  type DOCSIS
  qam-profile 1
  frequency 381000000
  rf-output NORMAL
  docsis-channel-id 1

cable downstream controller-profile 2
 max-carrier 158
 max-ofdm-spectrum 384000000
 rf-chan 158
  docsis-channel-id 159
  ofdm channel-profile 20 start-frequency 579000000 width 48000000 plc 600000000


cable rpd test
 identifier 0001.0001.0001
 type shelf
 rpd-ds 0 max-carrier 128
 rpd-ds 0 base-power 33
 rpd-ds 1 max-carrier 158
 rpd-ds 1 base-power 25
 core-interface Te9/1/0
  rpd-ds 0 downstream-cable 9/0/3 profile 1
  rpd-ds 0 downstream-cable 9/0/4 profile 2
  rpd-us 0 upstream-cable 9/0/3 profile 1
 r-dti 1
 rpd-event profile 0
 rpd-55d1-us-event profile 0

Note

It is highly recommended to follow this example to check and update configuration if necessary because max-carrier value is used to compute the base power. Otherwise, after upgrade the expected base power value can be different which may affect cable modem coming online.

Note

If you upgrade from a version lower than Cisco IOS XE Fuji 16.9.1, base power range may be changed on the port with OFDM channel configured. So be aware of the potential base power change before and after the upgrade.

Upgrading from Cisco IOS XE 16.x and later releases to Cisco IOS XE Bengaluru 17.6.1z

If you are upgrading from Cisco IOS XE Everest 16.6.x or Cisco IOS XE Fuji 16.7.x to Cisco IOS XE Bengaluru 17.6.1z, perform the following steps to upgrade SUP ROMMON manually. Otherwise proceed with the IOS upgrade.

Download hardware programmable devices upgrade package file cbrsup-programmable_firmware.17.06.01z.SPA.pkg from the following Cisco.com Software Center URL: https://software.cisco.com/download/home/286283913/type

Copy the package file to harddisk:.

copy <location>/cbrsup-programmable_firmware.17.06.01z.SPA.pkg harddisk:

Verify the hardware programmable devices upgrade package against the md5 hash as provided in the Cisco.com Software center.
```
verify /md5 harddisk:cbrsup-programmable_firmware.17.06.01z.SPA.pkg
```

Upgrade SUP ROMMON.

Note

Do not restart the SUPs currently, you can combine reloading the SUP with the IOS upgrade process.

If you are using cBR CCAP 8x10G Remote PHY Digital Physical Interface Card (D-PIC) with CBR-CCAP-LC-G2-R linecards, before upgrading to Cisco IOS XE Bengaluru 17.6.1z, contact your local Cisco representative to get the python tool and perform the following steps in order to predict and avoid downtime. This python tool is developed by Cisco, it is used to analyze the cBR-8 configuration file to determine if the configuration file includes non-compliant TenGigabitEthernet interface to downstream controller mappings, and update the configuration file to be compliant with the latest Cisco IOS XE Bengaluru 17.6.1z.

Collect the following information from the target cBR-8 to upgrade.


Router#show cable rpd sum
Router#show cable modem sum
Router#show cable video session all sum

Save the running configuration to the harddisk of the cBR-8.
```
Router#copy running-config harddisk:SavedConfig.txt
```
Copy the saved running configuration from harddisk: to an offline server for editing using SCP.
```
Router#copy harddisk:SavedConfig.txt scp:<path>
```
Run the python tool to modify the controllers in the saved configuration.
- Option 1 - Renumber Downstream-Cable controllers only
  1. Execute python script kobol_ph2_controller_migration.py. This script is intended for customers who do not immediately intend to take advantage of the Downstream-Video controllers and expanded SG capacity on CBR-CCAP-LC-G2-R.
```
$ python kobol_ph2_controller_migration.py
Enter the name of the configuration file: SavedConfig.txt
```
  2. Output file appends _remap_controller to the file name.
```
Output file name: SavedConfig.txt_remap_controller
```
  3. Check to ensure that the script completed successfully. If no output file is created or the size of the output file is 0 byte, then check script output for error messages.
- Option 2 - Renumber Downstream-Cable and utilize Downstream-Video controllers
  1. Execute python script kobol_ph2_controller_migration_video.py. This script is intended for customers who wish to utilize the new Downstream-Video controllers to free up existing Downstream-Cable controllers for expanded DOCSIS service groups.
```
$ python kobol_ph2_controller_migration_video.py
Enter the name of the configuration file: SavedConfig.txt
```
  2. Output file appends _remap_controller_video to the file name.
```
Output file name: SavedConfig.txt_remap_controller_video
```
  3. Check to ensure that the script completed successfully. If no output file is created or the size of the output file is 0 byte, then check script output for error messages.
Modify the remapped configuration file to specify the Cisco IOS XE Bengaluru 17.6.1z image in the boot parameter.
```
boot system harddisk:cbrsup-universalk9.17.06.01z.SPA.bin
```

Copy the final remapped configuration file back to the cBR-8 harddisk.

Router#copy scp:<path>/SavedConfig.txt_remap_controller harddisk:

Router#copy scp:<path>/SavedConfig.txt_remap_controller_video harddisk:

Copy remapped configuration file to startup of the cBR-8.

```
Use the following steps if you use cBR CCAP 8x10G Remote PHY Digital Physical Interface Card (D-PIC) with CBR-CCAP-LC-40G-R linecards.
```
configure terminal
config-register 0x2102
end
```

Step 6

Check line card CPLD version via show platform . If it is not the minimum version 00000026, upgrade line card CPLD following the sub steps below. Otherwise skip this step.

Note

To upgrade the line card CPLD to version 00000026, the cBR-8 must be running Cisco IOS XE Gibraltar 16.12.1 or later releases.

This procedure will trigger a reload of the linecard and will cause an outage if the system is not backed up with LCHA.

Do not power cycle the cBR-8 router during the firmware upgrade process. Power cycling the chassis may corrupt the ROMMON/Uboot image.

Run the following pre-upgrade commands on the SUP IOS:


upgrade hw-programmable cable active_SUP daggit pre-upgrade slot LC_slot_#

Example:

Router# upgrade hw-programmable cable R0 daggit pre-upgrade slot 0
Daggits pre-upgrade successful

Upgrade the line card CPLD firmware using the SUP IOS command.

Note

Do not reboot the line card until the upgrade is complete. Upgrade takes approximately 15 minutes.


upgrade hw-programmable cable LC_slot_# daggit pkg_name firmware_pkg_location_path

Example:

Router# upgrade hw-programmable cable 0 daggit pkg_name /harddisk/cbrsup-programmable_firmware.17.06.01z.SPA.pkg

After the upgrade is complete (takes approximately 15 minutes), the line card moves to unknown state. Check the status of the line card using the show platform command. When the line card is in unknown state, run the following command to recover the line card:
```
upgrade hw-programmable cable active_SUP daggit lc-recovery slot LC_slot_# 
```
Example:
```
Router# upgrade hw-programmable cable R0 daggit lc-recovery slot 0
```

The line card moves from booting to active state. Check the version of the line card using the show platform command to make sure version is changed to 00000026.

Example:

 
Router#show platform
……
Slot      CPLD Version        Rommon Version
--------- ------------------- ---------------------------------------

0         00000026            2011.03.18
…

When the line card is in active state, run the following command to verify the upgrade.


upgrade hw-programmable cable active_SUP daggit post-active slot LC_slot_#

Example:

 
Router# upgrade hw-programmable cable R0 daggit post-active slot 0
SUCCESS: Daggit_ver-38 : Booted from upgradable Image-1

Step 7

Check the firmware version of the Docsis 3.1 downstream modules in all slots, if it is different with the version listed in Table 1, update the firmware using the following command. Otherwise skip this step.


upgrade hw-programmable cable slot dsphy all pkg_name firmware_pkg_location_path

Example:

 
Router# upgrade hw-programmable cable 0 dsphy all pkg_name /harddisk/cbrsup-programmable_firmware.17.06.01z.SPA.pkg

Step 8

Wait for the system log message asking the user to reload the line card that was upgraded.

001860: Jun 15 19:05:05.904 PDT: %IOSXE-5-PLATFORM: CLC0: cdman: Suggest reload the line card for new FW to take effect using CLI: hw slot <slot-id> reload

Step 9

Reload the system.

Router#reload

During reload, monitor the chassis for any of the following errors, and update the configuration accordingly.


Mismatches TE interface. DS controller should be */*/0~7, configuration failed.
Mismatches TE interface. DS controller should be */*/8~15, configuration failed.
Mismatches TE interface. DS controller should be */*/16~23, configuration failed.
Mismatches TE interface. DS controller should be */*/24~31, configuration failed.

Step 10

If the system is running with SUP250, perform no shut on 100G interface after the system comes up for the first time.

What to do next

Perform verification test to determine if the upgrade is successful, include:

Verify the router is running the new IOS-XE release using show version command.
Check facility alarms using show facility-alarm status command.

Upgrading cBR CCAP 8x10G Remote PHY Digital Physical Interface Card

Before you begin

Before upgrading the system, make sure the following requirements are met:

Make sure the latest available IOS XE version is active in Cisco cBR-8 router.
There are at lease 20MB free space on the harddisk.

Note

To make use of the new features, it is recommended to upgrade the cBR CCAP 8x10G Remote PHY Digital Physical Interface Card (D-PIC) to the latest version 1.1.

Procedure

Step 1

Boot up system, wait until IOS is ready.

Step 2

Check current D-PIC version.


show hw-module subslot x/1 fpd

Note

x/1 is D-PIC subslot number which needs upgrade.

Example:


Router#show hw-module subslot 9/1 fpd

==== ====================== ====== =============================================
                             H/W   Field Programmable   Current   Min. Required
Slot Card Type               Ver.  Device: "ID-Name"    Version      Version
==== ====================== ====== ================== =========== ==============
 9/1 CBR-DPIC-8X10G          1.0   46-CBR DIGI PIC        1.0         1.0
==== ====================== ====== =============================================

Step 3

Upgrade D-PIC.


upgrade hw-module subslot x/1 fpd bundled reload

Example:


Router#upgrade hw-module subslot 9/1 fpd bundled reload

% The following FPD will be upgraded for CBR-DPIC-8X10G (H/W ver = 1.0) in subslot 9/1:

  ================== =========== =========== ============ 
  Field Programmable   Current     Upgrade   Estimated 
  Device: "ID-Name"    Version     Version   Upgrade Time 
  ================== =========== =========== ============ 
  46-CBR DIGI PIC        1.0         1.1       00:05:00
  ================== =========== =========== ============ 

% NOTES:
  - Use 'show upgrade fpd progress' command to view the progress of the FPD
    upgrade.
  - The target card will be automatically reloaded after the upgrade 
    operation. This reload will interrupt normal operation of the card. If 
    necessary, ensure that appropriate actions have been taken to redirect 
    card traffic before starting the FPD upgrade.

% Are you sure that you want to perform this operation? [no]: yes
% Initiating the upgrade operation on the target card ...
  (Use "show upgrade fpd progress" command to see upgrade progress)

Step 4

Check if the upgrade process is finished. Upgrade progress will take about 1 to 2 minutes.
