Upgrading Cisco IOS-XE software to release 3.18.1SP


Note

If the system image is upgraded using ISSU, after the ISSU upgrade is finished, use hw-module subslot 4/1 reload and hw-module subslot 5/1 reload commands to upgrade the SUP MAC firmware.

Before You Begin

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

  • Download the new image package from the following URL:

    https:/​/​software.cisco.com/​download/​navigator.html

  • Copy the new image package to the cBR-8 using TFTP. 

    copy tftp://<location>/cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin bootflash:
copy tftp://<location>/cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin stby-bootflash:

  • Verify the new image package against the known md5 hash. 

    verify /md5 bootflash:cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin
verify /md5 stby-bootflash:cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin

Upgrading in Consolidated Package Mode

    Step 1   Change the boot variable to point to the desired new image. 
    configure terminal
no boot system
boot system bootflash:cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin
end
write memory
    Step 2   Verify that the bootvar has changed to point to the new image using show bootvar command.
    Step 3   Reload cBR-8 router. 
    reload

    Upgrading in Subpackage Mode

      Step 1   Extract the individual subpackages and the provisioning file from a consolidated package to a specific image based directory in the bootflash. 
      request platform software package expand file bootflash:cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin to bootflash:/<location>/ wipe
request platform software package expand file stby-bootflash:cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin to stby-bootflash:/<location>/ wipe
      Step 2   Verify the list of sub-packages and helper files are created in the directory specified in last step using dir command.
      Step 3   Change the boot variable to point to the desired new IOS-XE image. 
      configure terminal
no boot system
boot system bootflash:cbrsup-universalk9.03.18.01.SP.156-2.SP1-ext.SPA.bin
end
write memory
      Step 4   Verify that the bootvar has changed to point to the new image using show bootvar command.
      Step 5   Reload cBR-8 router. 
      reload

      Upgrading Firmwares

      The correct firmware versions after the upgrade are listed in the tables below. Use the commands in the tables to verify the firmware versions.

      Before You Begin

      Make sure the Cisco cBR-8 router software is upgraded to Cisco IOS-XE release 3.18.1SP.

      Upgrading Docsis 3.1 and Docsis 3.0 Downstream Module Firmwares


      Note

      If the Cisco IOS-XE release is 3.18.1S or 3.18.0SP before upgrading to Cisco IOS-XE release 3.18.1SP, the downstream module upgrade procedure can be performed before Cisco IOS-XE software upgrade, in this way, there is no need to reset the linecard during the upgrade, since linecard will be reloaded during Cisco IOS-XE software upgrade.

      For detailed upgrading steps, see Upgrading Docsis 3.0 downstream module and Docsis 3.1 downstream module (Cisco IOS-XE Release 3.18.1S and later releases).

          Upgrading Cisco cBR-8 Router from Cisco IOS-XE release 3.17.0S to Cisco IOS-XE release 3.17.1S

          Cisco cBR-8 Routers support the In-Service Software Upgrades (ISSU) for redundant platforms. The ISSU process allows software to be updated or otherwise modified while packet forwarding continues with the benefit of LCHA. ISSU supports subpackage software upgrade mode. For more information, please refer to Cisco IOS-XE In-Service Software Upgrade Process.

          This use case provides the example procedure to upgrade a Cisco cBR-8 router from IOS-XE release 3.17.0S to IOS-XE release 3.17.1S with subpackage mode.

          Before You Begin

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

          • Verify the chassis is in subpackage mode.

            If the chassis is not in subpackage mode, change it to subpackage mode following the steps below:

            1. Expand the IOS-XE binary image file to a specific image based directory in the bootflash using the following commands: 

              request platform software package expand file bootflash: cbrsup-universalk9.03.17.00.S.156-1.S-std.SPA.bin to bootflash:/XE317/ wipe
request platform software package expand file stby-bootflash: cbrsup-universalk9.03.17.00.S.156-1.S-std.SPA.bin to stby-bootflash:/XE317/ wipe

            2. Verify that the following list of sub-packages and helper files are created in the directory using dir bootflash:/XE317/ and dir stby-bootflash:/XE317/ commands.

            3. Change boot statement to point to the subpackage mode using following commands: 

              configure terminal
no boot system
boot system bootflash:/XE317/cbrsup-packages-universalk9.03.17.00.S.156-1.S-ext.conf
end
write memory

            4. Verify peer SUP is in hot standby state using show redundancy command.

            5. Switchover from SUP0 to SUP1 using redundancy force-switchover command.

            6. Wait and verify SUP0 is in hot standby state using show redundancy command.

            7. Switchover from SUP1 to SUP0 using redundancy force-switchover command.

            8. Wait and verify SUP1 is in hot standby state using show redundancy command.

            9. Verify the system is running in subpackage mode using show version command. System image file should point to a .conf package file. Below is a sample output: 

              cBR8-01 uptime is 6 weeks, 4 days, 5 hours, 36 minutes
	Uptime for this control processor is 6 weeks, 4 days, 4 hours, 57 minutes
	System returned to ROM by SSO Switchover at 10:33:32 est Thu Nov 19 2015
	System restarted at 11:19:15 est Thu Nov 19 2015
	System image file is "bootflash:/Upgrade/packages.conf"

            10. Verify the directory in which the .conf file is booted. You will see packages.conf along with a list of package files ending with SPA.pkg.

          • Verify both SUPs are running the same image from the same path using show version | include image command. Below is a sample output: 

            Router# show version | include image
System image file is "bootflash:XE317/packages.conf"

          • Verify autoboot is enabled using show bootvar command. Below is a sample output: 

            Router# show bootvar
BOOT variable = bootflash:XE317/packages.conf,12;
CONFIG_FILE variable = 
BOOTLDR variable does not exist
Configuration register is 0x2102

Standby BOOT variable = bootflash:XE317/packages.conf,12;
Standby CONFIG_FILE variable = 
Standby BOOTLDR variable does not exist
Standby Configuration register is 0x2102

          • Verify both SUPs are in SSO mode, standby SUP is in hot standby mode using show redundancy state command. Below is a sample output: 

            Router# show redundancy state
       my state = 13 -ACTIVE 
     peer state = 8  -STANDBY HOT 
           Mode = Duplex
           Unit = Primary
        Unit ID = 48

Redundancy Mode (Operational) = sso
Redundancy Mode (Configured)  = sso
Redundancy State              = sso
     Maintenance Mode = Disabled
    Manual Swact = enabled
 Communications = Up

   client count = 119
 client_notification_TMR = 30000 milliseconds
           RF debug mask = 0x0

          • Make sure there is enough bootflash disk space on both SUPs (available space more than 1.8GB).

          • Verify the IOS-XE release 3.17.1S image file against the known file md5 hash using verify /md5 cbrsup-universalk9.03.17.01.S.156-1.S1-std.SPA.bin command.

          • Put IOS-XE release 3.17.1S image cbrsup-universalk9.03.17.01.S.156-1.S1-std.SPA.bin in the same folder as current boot package on active SUP using dir bootflash:/XE317/cbrsup-universalk9.03.17.01.S.156-1.S1-std.SPA.bin command.

          • Verify .issu folder and config files exists on both active and standby SUP hard disk using dir harddisk:.issu/ command. Below is a sample output: 

            Router# dir harddisk:.issu/
Directory of harddisk:/.issu/

            If there is no such folder or file is missing, create a new one and generate files needed. Below are sample commands: 

            Router# mkdir harddisk:.issu
Router# mkdir stby-harddisk:.issu
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/rp.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/remote_rp.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/0.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/1.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/2.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/3.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/6.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/7.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/8.conf
Router# copy bootflash:/XE317/packages.conf harddisk:.issu/9.conf

Router# copy harddisk:.issu/rp.conf stby-harddisk:.issu/rp.conf 
Router# copy harddisk:.issu/remote_rp.conf stby-harddisk:.issu/remote_rp.conf
Router# copy harddisk:.issu/0.conf stby-harddisk:.issu/0.conf 
Router# copy harddisk:.issu/1.conf stby-harddisk:.issu/1.conf 
Router# copy harddisk:.issu/2.conf stby-harddisk:.issu/2.conf

Router# copy harddisk:.issu/7.conf stby-harddisk:.issu/7.conf 
Router# copy harddisk:.issu/8.conf stby-harddisk:.issu/8.conf 
Router# copy harddisk:.issu/9.conf stby-harddisk:.issu/9.conf

            Note

            The file with digital as the name corresponds with line card slot, the above example is for fully loaded chassis. If target system is not fully loaded, just copy the files named with inserted slot number.

            Step 1   Perform RP only ISSU. 
            request platform software package install node file bootflash:XE317/cbrsup-universalk9.03.17.01.S.156-1.S1-std.SPA.bin noreload linecard
            Note   

            Do not interrupt the terminal until ISSU performs automatic SUP switchover.

            Step 2   Attach to ISSU progress status tracking mode after SUP switchover. User can use Ctrl+C to exit to perform other command if needed. 
            request platform software package install node attach

            Below is a sample output: 

            NOTE: Currently node has booted from a provisioning file
NOTE: Going to resume a dual rp sub-pakcage node ISSU install

--- Starting wait for Standby RP to reach terminal redundancy state ---
            Step 3   Reset secondary line card (change slot 0 to secondary slot on target chassis). 
            hw-module slot 0 reload
            Step 4   Upgrade all line cards. 
            request platform software package install node linecard-only all
            Note   

            Do not interrupt the terminal until ISSU is successfully complete.

            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.


              Note

              Some deployments use 5 power supplies which are sufficient, but will show an major alarm which can be ignored.

            • Check the status of the power supplies using show environment power command.

            • Check PS status using show platform hardware slot P<0-5> mcu status command.

            • Complete trace routes to known good off-network IP address using the source address of customer CPE blocks to verify routing is working.

            • Check logs for error messages using show log command.

            These show commands may be useful in the verification test:

            • show redundancy
            • show platform
            • show platform diag
            • show environment
            • show redundancy linecard all
            • show isis neighbors
            • show ip route rip
            • show ip mroute
            • show cops servers
            • show cable modem voice
            • show cable calls
            • show cable metering verbose
            • show cable licenses all
            • show cable modem summary total
            • show inventory
            • Request platform software console attach slot-id/0 and show version
