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: Loading, Loaded,
Switching (during an upgrade to a compatible version), Switchover (during an upgrade to a compatible
version), or Accepted. If you perform a manual rollback while the ISSU is in Loading state, the ISSU
process ends without changing the original software configuration.
When an ISSU to an incompatible version is in Switching state, you cannot perform a manual rollback.
When the ISSU is in Committing state, rollback is not supported.
In IRF mode, 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 configuration.
<Sysname> issu rollback
This command will quit the ISSU process and roll back to the previous version. Continue?
