Upgrading RPD and cBR-8 Router

The following scenarios are supported for upgrading the RPD and cBR-8 router.


cBR-8 original version	RPD original version	RPD state before upgrade	cBR-8 upgrade version	RPD upgrade version	RPD state after upgrade
Lower than 17.2.1	Lower than 8.4	online	17.2.1	8.4	online
Lower than 17.2.1	Lower than 8.4	init(gcp)	17.2.1	8.4	online

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

Download the two files from the following Cisco.com Software Center URL:
- IOS XE Software Version 17.2.1 cbrsup-universalk9.17.02.01.SPA.bin: https://software.cisco.com/download/home/286283913/type

Console access for both SUP line cards is required.

Note

For more information on how to upgrade the Cisco cBR-8 router, see Upgrading the Cisco cBR Series Converged Broadband Routers for Cisco IOS XE Amsterdam 17.2.x. When upgrading Cisco cBR-8 router, should there be any difference between the steps in Upgrading the Cisco cBR Series Converged Broadband Routers for Cisco IOS XE Amsterdam 17.2.x and the following steps, the Cisco cBR-8 Upgrade Guide would prevail.

Copy the Cisco IOS XE Amsterdam 17.2.1 package to bootflash and stby-bootflash:

copy <location>/cbrsup-universalk9.17.02.01.SPA.bin bootflash: 
copy <location>/cbrsup-universalk9.17.02.01.SPA.bin stby-bootflash:

Verify the Cisco IOS XE Amsterdam 17.2.1 package against the md5 hash as provided in the Cisco.com Software center.

verify /md5 bootflash:cbrsup-universalk9.17.02.01.SPA.bin 
verify /md5 stby-bootflash:cbrsup-universalk9.17.02.01.SPA.bin

Back up the current running config to bootflash.
```
copy running-config bootflash:pre-upgrade.cfg
```
Check the system status before the upgrade. Save the information to compare against the system status after the upgrade. For commands on checking the status, see the show commands at the end of this section.
Copy the Cisco RPD image to a TFTP server that is accessible by the RPDs.
Verify the current RPD software version by running the following command:
```
show cable rpd sw-version
```

Upgrade all RPD images to version 8.4 by using SSD from the Cisco cBR-8 router.

cable rpd all ssd <tftp_server_ip> tftp <rpd_V8.4_file_path>

Note

The all command is not recommended in large-scale RPD deployments. If you have a larger number of RPDs, it is recommended to upgrade the RPD per line card or per OUI.

Verify RPD SSD status.
The status will show as downloading.
```
cable rpd all ssd status
```
Verify that all RPDs have downloaded the new image.
```
cable rpd all ssd status
show cable rpd
```

Configure the chassis to boot the system with Cisco IOS XE Amsterdam 17.2.1 image. Save the running configuration.

configure terminal
no boot system
boot system bootflash:cbrsup-universalk9.17.02.01.SPA.bin
config-register 0x2102
end
copy running-config startup-config

Reload and start the Cisco cBR-8 router.
```
Reload
```
Adjust the RPD type/max-carrier/base-power as necessary.

If you upgrade the Compact Shelf from Cisco IOS XE Everest 16.5.x or Cisco IOS XE Everest 16.6.x to Cisco IOS XE Fuji 16.7.x or later, you must change the RPD type to shelf. By default the RPD type is Node. Adjust the related base-power according to your requirement.
Verify that the RPDs have been upgraded to new version and are online.
```
show cable rpd
show cable rpd sw-version
