Performing an ISSU by using issu series
commands

Performing an ISSU in standalone mode

When you use the issu series commands to install or upgrade the software of MPUs, the device
automatically install or upgrade the software of the service cards as needed. You do not need to install
or upgrade the software of the service cards separately.
The ISSU procedure varies depending on whether the device has a single or two MPUs.

Performing an ISSU for a dual-MPU device

Before upgrade, use the display version comp-matrix file { boot filename | system filename | feature
filename&<1-30> } * or the display version comp-matrix file ipe ipe-filename command to display the
compatibility between the new and old images and the upgrade methods to be used:
• If a new image is on the Version compatibility list, the new and old images are compatible.
If a new image is not on the Version compatibility list, the new and old images are incompatible.
•
To perform an ISSU for a compatible version, execute the following commands:
Step
1. Enter system view.
2. (Optional.) Display
automatic-rollback timer
information.
3. (Optional.) Set the
automatic rollback timer.
4. Return to user view.

main startup software
images for the standby
MPU.

Remarks
N/A
If you don't think the ISSU can be
finished before the timer expires, adjust
the timer.
By default, the automatic-rollback
interval is 45 minutes.
This timer is started when you execute the
issu run switchover command. If you do
not execute the issu accept or issu commit
command before this timer expires, the
system automatically rolls back to the
original software configuration.
N/A
Specify the slot number of the standby
MPU for the slot slot-number option.
