Parameters
minutes: Specifies the automatic rollback interval in minutes, in the range of 0 to 120. Setting it to 0
disables the automatic rollback feature.
Usage guidelines
The automatic software version rollback feature is only available on a multichassis IRF fabric during
an ISSU to a compatible version.
The system starts the automatic rollback timer w hen you execute the issu run switchover
command in a scenario where automatic rollback is supported. If you do not execute the issu accept
or issu commit command before the timer expires, the system automatically rolls back to the
software versions before 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.

Usage guidelines
Use this command on multichassis IRF fabrics.
•
For a compatible version, this command performs tasks depending on the ISSU method:
Incremental upgrade—Performs a process-level master/subordinate switchover for the
processes to be upgraded.
Reboot upgrade or ISSU upgrade—Reboots the current master with the old software
version, causing the upgraded subordinate member to be elected as the new master.
•
For an incompatible version, the issu load command splits the IRF fabric into two fabrics, with
the upgraded members forming a new fabric. The issu run switchover command reboots the
members in the old IRF fabric with the upgrade images. After startup, the members join the new
IRF fabric as subordinate members.
At reboot, a subordinate device automatically synchronizes the master device's configuration and
status data. You must wait for the synchronization to complete before using the issu run switchover
command on the subordinate device. To check the synchronization progress, use the display device
command. The synchronization is completed when all member device are in normal state.
