ISSU Commands
94 New and Enhanced Features in AlliedWare Plus 5.4.4 Major and Minor Versions
issu boot
To perform an ISSU, you must have a chassis (or VCStack Plus) with more than one CFC960
(Controller Fabric Card). Note that ISSU will not run with CFC400 cards, nor will it run if
there is already an ISSU process in progress. Therefore a new ISSU cannot start until all
CFC960s and LIFs (Line Interace cards) are running with the same software release.
The software specified by the Command Line Interface (CLI) must be a valid AW+ release
for the running system and on the same maintenance branch as the currently running
software, such as version 5.4.4.
If any of these preconditions are not met, ISSU will not start, and a warning message will
be printed to the console.
In a VCStack Plus configuration, if one of the chassis has only a single CFC, the console will
first display a warning message followed by a confirmation message.

Parameter Description
<file> URL of the release file - either a USB or Flash. Note that if set to a
release on USB, then each CFC requires a USB drive to be present. The
new release will then be synced to each USB drive, and the location
ISSU boots each CFC from will be USB. We recommend that the file be
loaded from Flash.
