Upgrading from Cisco IOS XE 16.x and later releases to Cisco IOS XE Dublin 17.12.1w
Prerequisites
Manual ROMMON Upgrade
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 17.12.1w, perform the following steps to upgrade SUP ROMMON manually.
-
Download hardware programmable devices upgrade package file cbrsup-programmable_firmware.17.12.01w.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.17.12.01w.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.17.12.01w.SPA.pkg
-
Upgrade SUP ROMMON.
Router#upgrade rom-mon file harddisk:cbrsup-programmable_firmware.17.12.01w.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.17.12.01w.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
Note
Do not restart the SUPs currently, you can combine reloading the SUP with the IOS upgrade process.
Downstream-Controller Remapping (CBR-CCAP-LC-G2-R with 8x10G DPIC)
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 17.12.1w.
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 17.12.1w. 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.
-
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
-
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
-
Output file appends _remap_controller to the file name.
Output file name: SavedConfig.txt_remap_controller
-
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
-
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
-
Output file appends _remap_controller_video to the file name.
Output file name: SavedConfig.txt_remap_controller_video
-
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 17.12.1w image in the boot parameter.
boot system harddisk:cbrsup-universalk9.17.12.01w.SPA.bin
-
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:
-
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.
