Description
In standalone mode
1.
Use the issu run switchover command to perform a manual active and standby switchover.
For compatible versions, executing the issu run switchover command is the second step in the ISSU
upgrade process. After you execute the issu run switchover command, these are the results:
The active MPU reboots with the previous version.
The upgraded standby MPU that is specified at the CLI becomes the active MPU.
The system upgrades all LPUs by installing hotfixes. For LPUs that have no upgrade hotfixes or do not
support this upgrade method, the system upgrades the cards by rebooting them.
For incompatible versions, executing the issu run switchover command is the last step in the ISSU
upgrade process. After you execute the issu run switchover command, these are the results:
The active MPU reboots with the new version and all LPUs reboot to upgrade.
The standby MPU becomes the new active MPU.
The ISSU process is completed after all MPUs and LPUs reboot.
For compatible versions, if you do not execute the issu accept or issu commit command before the
specified rollback timer expires, the system automatically stops the ISSU process and reverts to the
previous software version.
Avoid configuring the system, performing an active and standby switchover, and plugging/unplugging
a card during the ISSU upgrade.
