ISSU Upgrade for Redundant Platforms Command or Action Step 17 issu runversion Example: Router# issu runversion Step 18 telnet ip-address port Example: [unix-server-1 ~]$ telnet 172.17.52.157 2003 User Access Verification Username: user Password: ******** Router> Step 19 issu acceptversion Step 20 Example: Router# issu acceptversion issu commitversion Example: Router# issu commitversion Software Upgrade Process Purpose Run the consolidated package that was loaded in Step 16. Note If this command is entered before the terminal state is reached, a "peer is not online" or "Standby RP is not in terminal state" error message will be seen and the issu runversion command will not work. If the issu runversion command does not run for these reasons, wait for the "terminal state is reached" message to appear and retry the issu runversion command. You can also monitor the terminal state using the show platform command. After ISSU runversion is completed, a switchover will automatically occur and the standby RP will become the active RP. Log in to the RP being upgraded, preferably using the RP's console port, to complete the upgrade. (This is the new active RP, that was the standby RP prior to the ISSU process.) Note Ensure the hostname does not end in "-stby" after logging into the RP, as this indicates that the RP being accessed is still the standby RP. There are many ways to log on to a console port. The example shows access to the console port from a UNIX host using telnet. (Optional) Stops the ISSU rollback timer. This step is optional as long as Step 20 is completed before the rollback timer expires. Completes the ISSU upgrade. Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide 8
