Usage guidelines
The device supports automatic rollback and manual rollback. This command performs a manual
rollback.
You can perform a manual rollback while an ISSU is in one of the following states:
•
Loaded.
•
Switching.
•
Switchover.
•
Accepted.
If you perform a manual rollback while an ISSU is in Loading state, the rollback might fail. After the
rollback is completed, use the
display version
command to examine the rollback result.
If a rollback occurs while an ISSU is in Switching state, the entire system reboots automatically.
When an ISSU is in Committing state, rollback is not supported.
A rollback performed for a multichassis IRF fabric after you execute the
issu run switchover
command
cancels only the upgrades. The master/subordinate switchover operation is not canceled.
Examples
# Roll back to the original software versions.
<Sysname> issu rollback
This command will quit the ISSU process and roll back to the previous version. Continue?
