Parameters
minutes: Specifies the automatic-rollback interval in minutes, in the range of 0 to 120. Setting it to 0
disables the automatic rollback function.
Usage guidelines
The automatic software version rollback function is only available on a multichassis IRF fabric, a
dual-MPU device, a multichassis IRF fabric, or a single-chassis dual-MPU IRF fabric during an ISSU to a
compatible version.
When you execute the issu run switchover command in a scenario where automatic rollback is
supported, the system starts the automatic-rollback timer. If you do not execute the issu accept or issu
commit command before the timer expires, the system automatically rolls back to the original software
configuration, the software configuration prior to the ISSU.
Change to the automatic-rollback interval does not take effect on the ongoing ISSU process.
Examples
# Set the automatic-rollback timer to 50 minutes.
