Automating the ISSU Process Using

Triggers

You will probably want to upgrade your software at a convenient time for your operation.

One possibility is to upgrade the CFCs during a time when technical staff are available and

use the automatic phase of ISSU to eliminate, or at least reduce, system downtime. Then

use triggers to apply the line card upgrades for a period when the network has either a

low usage, or a scheduled maintenance period.

In the following example, we assume that the automatic phase of ISSU has been

successfully completed, and that you want to use triggers to implement a reboot of your

line cards.

Step 1: Quantify the line cards that need to be upgraded

Use the following command to display summary information about the cards in your

switch or VCStack Plus.:

Caution

ISSU trigger scripts that use any type other than “ISSU Completed” must

not place the switch into Configuration Mode.
