Usage guidelines
The device supports automatic rollback and manual rollback.
You can use this command to perform a manual rollback while an ISSU is in one of the following
states:
•
Loaded.
•
Switching.
•
Switchover.
•
Accepted.
If the ISSU is in Loading state, the rollback might fail. Use the
display version
command to examine
the rollback result after the ISSU is complete.
If the ISSU is in Switching state, the entire system reboots automatically.
A rollback cancels only the software upgrade. It does not cancel the master/subordinate switchover
you performed before the rollback by executing the
issu run switchover
command.
Rollback is not supported while an ISSU is in Committing state.
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?
