Upgrading the Cisco cBR-8 Router System to Cisco IOS XE Dublin 17.15.1x


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 is automatically updated to the new version after upgrading to Cisco IOS XE Dublin 17.15.1x. 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

Downstream-Controller Remapping (CBR-CCAP-LC-G2-R with 8x10G DPIC)

Starting with Cisco IOS XE Bengaluru 17.6.1, Cisco introduced a new feature on cBR-8 that provides initial support for 32 Video and 32 DOCSIS service groups per CBR-CCAP-LC-G2-R linecard. However, there are specific configuration considerations when using 8x10G Remote PHY Digital Physical Interface Card (D-PIC) with CBR-CCAP-LC-G2-R linecards.

If you are upgrading from Cisco IOS XE Amsterdam 17.3.1 or earlier, and you are using 8x10G Remote PHY Digital Physical Interface Card (D-PIC) with CBR-CCAP-LC-G2-R linecards, see the section entitled Downstream-Controller Remapping (CBR-CCAP-LC-G2-R with 8x10G DPIC) below. Further, it is recommended that you contact your local Cisco representative for assistance before upgrading to Cisco IOS XE Dublin 17.15.1x.

% 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

verify /md5 harddisk:cbrsup-programmable_firmware.17.15.01x.SPA.pkg

Step 3

Upgrade SUP ROMMON.

Router#upgrade rom-mon file harddisk:cbrsup-programmable_firmware.17.15.01x.SPA.pkg r0
Wait for the following output on the console:
ROMMON upgrade complete.
To make the new ROMMON permanent, you must restart the RP

Router#upgrade rom-mon file harddisk:cbrsup-programmable_firmware.17.15.01x.SPA.pkg r1
Wait for the following output on the console:
ROMMON upgrade complete.
To make the new ROMMON permanent, you must restart the RP

Step 4

Reload both the SUPs.

Downstream-Controller Remapping (CBR-CCAP-LC-G2-R with 8x10G DPIC)

Before you begin

If you are using cBR CCAP 8x10G Remote PHY Digital Physical Interface Card (D-PIC) with CBR-CCAP-LC-G2-R linecards, contact your local Cisco representative before upgrading to Cisco IOS XE Dublin 17.15.1x.

Starting with in Cisco IOS XE Bengaluru 17.6.1, Cisco introduces a new feature on cBR-8 that provides initial support for 32 Video and 32 DOCSIS service groups per CBR-CCAP-LC-G2-R linecard. The implementation of this feature introduces new 8x10G DPIC port mapping constraints on existing 'Downstream-Cable' controllers. Cisco has prepared a python tool that can be used to determine if a cBR-8 running-configuration includes non-compliant controller mappings, and, to update the running-confirguration to be compliant with the latest Cisco IOS XE Dublin 17.15.1x. Once you have the python tool, perform the following steps in order to predict and avoid downtime:

Before you begin: Special considerations must be taken when using SmartPHY. Contact your local Cisco representative if your installation includes SmartPHY.

Procedure

Step 1

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

Step 2

Save the running configuration to the harddisk of the cBR-8.

Router#copy running-config harddisk:SavedConfig.txt

Step 3

Copy the saved running configuration from harddisk: to an offline server for editing using SCP.

Router#copy harddisk:SavedConfig.txt scp:<path>

Step 4

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.

Step 5

Modify the remapped configuration file to specify the Cisco IOS XE Dublin 17.15.1x image in the boot parameter.

boot system harddisk:cbrsup-universalk9.17.15.01x.SPA.bin

Step 6

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

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

or

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

Step 7

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

Router#copy harddisk:SavedConfig.txt_remap_controller startup-config

or

Router#copy harddisk:SavedConfig.txt_remap_controller_video startup-config

After performing the remapping procedure, monitor the chassis for any of the following errors after reload:

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.
