• To complete the ISSU process:
issu commit slot slot-number
• To roll back to the original software

issu rollback
Specify the slot number of the only MPU
for the slot slot-number option.
After the issu commit command is

use the issu rollback command to

ISSU process.
Performing an ISSU in IRF 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 and switching fabric cards as needed.
You do not need to install or upgrade the software of the service cards and switching fabric cards
separately.
The ISSU procedure varies by the number of member devices. For an IRF fabric with a single member, the
ISSU procedure varies by the number of MPUs.
