To do…
Use the command… Remarks
Reboot the master
current manually
issu run switchover slot
slot-number
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.
Accept the ISSU
issu accept slot
slot-number
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.
Upgrade an IRF member
switch that has not been
upgraded
issu commit slot
slot-number
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.
NOTE:
•
The roles of some IRF member switches change after an ISSU upgrade.
•
After executing the
issu commit
command, you cannot roll back the current system software image
version
BB to former version AA. To do so, use the AA version system software image as the new system
software image version to perform another ISSU for the IRF fabric.
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
.
