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 (during an upgrade to a compatible version).
• Switchover (during an upgrade to a compatible version).
• Accepted.
If the ISSU is in Loading state, the rollback might fail. Use the display version command to examine
the rollback result after the rollback is completed.
If a rollback occurs while an ISSU is in Switching state, the entire system reboots automatically.
A rollback performed for a multichassis IRF fabric after you execute the issu run switchover
command cancels all operations performed during the ISSU process, including the
master/subordinate switchover.
Examples
