The objective of this document is to help understand the steps involved in performing ISSU on Catalyst and Catalyst series switches. In-Service Software Upgrade ISSU is a process that upgrades an image to another image on a device while the network continues to forward packets. ISSU helps network administrators avoid a network outage when performing a software upgrade.

The images are upgraded in install mode wherein each package is upgraded individually. Also verify if ISSU is supported between current code and target code. Note : The example in this document is based on Cisco Catalyst switches configured as Stackwise-Virtual. Ensure that you have at least 1GB of space in flash to expand a new image. Clean up old installation files in case of insufficient space using "install remove inactive" command. Once all the pre-requisites are verified, you can proceeed with the actual upgrade using one of the methods below:.

NOTE : You cannot roll back as the upgrade is committed automatically. Proceed to 3-Step Work Flow if looking to roll back. If the rollback timer expires, the system rolls back to the same state before the start of the ISSU. The rollback timer can be stopped by using the install auto-abort-timer stop command. ISSU can be rolled back using install abort issu command. Next, the active switch is provisioned with the new software and it reloads.

The standby switch with the new image now becomes the active switch and the old active switch becomes the standby. At the end of this procedure, both the switches run with the new software image. The commit command performs the necessary clean up, enables the new software as permanent removing the older version of the software and stops the rollback timer.

Any reboot after the commit will boot with new software. Note : If the standby does not reach SSO during abort, manual abort is required.In-Service Software Upgrade ISSU is a process that upgrades an image to another image on a device while the network continues to forward packets.

ISSU helps network administrators avoid a network outage when performing a software upgrade. The images are upgraded in install mode wherein each package is upgraded individually. Restart the active switch and switchover the standby to new active switch. After the switchover, the new standby switch will be up with the new software. The new software image is already installed on the new active switch, hence ISSU is completed.

This workflow involves three steps—add, activate, and commit. After activation, all switches are upgraded to new software version except that the software is not committed automatically but must be performed manually via the install commit command. The advantage of this approach is the system can be rolled back to a previous software version.

The system automatically rolls back if the rollback timer is not stopped using the install abort-timer-stop or the install commit command.

If the rollback timer is stopped, the new software version could be run on the device for any duration and then rolled back to the previous version. This workflow involves only one step and helps in optimization. You cannot roll back as the upgrade is committed automatically. If the chassis is booted in a bundle mode, ISSU is not supported. Upgrading hardware and software simultaneously is not supported. Only one upgrade operation can be performed at a time. Automates the sequence of all upgrade procedures that include downloading the images to both the switches and expanding into packages, and upgrading each switch as per the procedure.
