Configuring incompatible ISSU
Use the display version comp-matrix file upgrading-filename command to view the versions of the new
and current system software images. If they are incompatible, perform an incompatible ISSU by following
Table 14.
Use the command...

Remarks
Required
With this command executed:
•
The master reboots with the current system software
image, and becomes a slave switch after reboot.
•
The slave switches of the IRF fabric perform master
election. The winner (the slave switch specified with
the issu load command) becomes the new master.
IMPORTANT:
•
The slot-number provided in this command must be
the same as that specified in the issu load command.
•
Perform the next operation after the reboot process is
completed.
Optional
By default, the rollback timer is 45 minutes. If you do not
execute the issu accept command on the specified slave
switch or you do not execute the issu commit command
on any other member switch before the rollback timer
expires, the system automatically stops the ISSU process
and reverts to the previous software version.
IMPORTANT:
•
The slot-number argument provided in this command
must be the same as that specified in the issu load
command.
•
When this command is executed, the rollback timer
becomes invalid, which means system software
cannot be automatically rolled back.
Required
•
This command upgrades one IRF member switch at a
time. If the IRF fabric has three or more than three
member switches, repeat this command to upgrade
them one by one.
•
When all the IRF member switches reboot with the
new system software image, the ISSU process
completes.
