Note

For more information about upgrading the cBR-8 router, see https:/​/​www.cisco.com/​c/​en/​us/​td/​docs/​cable/​cbr/​upgrade/​guide/​b_​cbr_​upgrade_​16_​7.html.

    Step 1   Copy Cisco IOS-XE Everest 16.6.2 package to bootflash: and stby-bootflash:. 
    copy <location>/cbrsup-universalk9.16.06.02.SPA.bin bootflash:
copy <location>/cbrsup-universalk9.16.06.02.SPA.bin stby-bootflash:
    Step 2   Verify Cisco IOS-XE Everest 16.6.2 package against the md5 hash as provided in the Cisco.com Software center. 
    verify /md5 bootflash:cbrsup-universalk9.16.06.02.SPA.bin
verify /md5 stby-bootflash:cbrsup-universalk9.16.06.02.SPA.bin
    Step 3   Backup current running config to bootflash:. 
    copy running-config bootflash:pre-upgrade.cfg
    Step 4   Check system status prior to upgrade. Save the information to compare against the system status after upgrade. For the commands to use to check the status, see the show commands at the end of this section.
    Step 5   Copy Cisco RPD V2.x image package to TFTP server that RPDs can reach to.
    Step 6   Verify current RPD software version. 
    show cable rpd sw-version
    Step 7   Upgrade all RPDs image to V2.x via SSD from cBR-8. 
    cable rpd all ssd <tftp_server_ip> tftp <rpd_V2.x_file_path>
    Note   

    all command is not suggested in large scale RPD deployment. If customer has too many RPDs, it is recommended to upgrade the RPD per LC or per OUI.

    Step 8   Verify RPD SSD status, should be in downloading status. 
    cable rpd all ssd status
    Step 9   Verify that all RPDs will start downloading new image then drop offline after a while. 
    cable rpd all ssd status
show cable rpd
    Step 10   Configure the chassis to boot the system with Cisco IOS-XE Everest 16.6.2 image and save running-configuration. 
    Configure terminal
no boot system
boot system bootflash:cbrsup-universalk9.16.06.02.SPA.bin
config-register 0x2102
end
copy running-config startup-config
    Step 11   Reload and bring up the cBR-8 router. 
    Reload
    Step 12   Check all RPDs have been upgraded to new version 2.x and come online succesfully. 
    show cable rpd
show cable rpd sw-version
