Upgrading the Application
Software
Overview
Upgrading the switch software involves the following steps:
1. Backing Up the Current Software
2. Backing Up the Previous Configuration
3. Downloading Application Software
4. Setting the Startup Image
5. Synchronizing the Active and Standby Supervisor Modules
6. Resetting the Active Supervisor
7. Resetting the Standby Supervisor
8. Verifying the Upgrade
This appendix contains procedures for each of these steps.
If a redundant supervisor module is running a 4.x version of
application software, it is not upgraded to v5.x if you follow this
upgrade procedure. To upgrade the application software from v4.x
to v5.x on a switch that has a redundant supervisor module, you
must upgrade the application software on each supervisor module
individually. For information on how to perform this task, see
“Upgrading from v4.x to v5.x” on page A-10.
If the switch has multiple VLANs statically bound to hunt group
ports, after upgrading from v5.x to v5.3.x, you must delete the hunt
groups and set them up again. For information on how to perform
this task, see “Upgrading a Switch with Multiple VLANs Statically
Bound to Hunt Group Ports” on page A-11.
