Changing the priority of a stack unit

To change the priority value for a stack unit, enter the priority command at the stack unit configuration level. The priority can be
a value from 0 through 255, where 255 is the highest priority.
device# configure terminal
device(config)# stack unit 1
device(config-unit-1)# priority 128

Stack software images

Consider the notes in this section when upgrading or downgrading a stack.
Refer to the release notes and to the Ruckus FastIron Software Upgrade Guide for instructions about upgrading the software.

Confirming stack software versions

All units in a stack must be running the same software image. To confirm this, check the software version on all devices that you
want to add to a stack. Upgrade any units that are running older versions of the software before you build the stack.
To check the software version for each stack member, perform the following steps.
1. Use Telnet or SSH or connect to any of the console ports in the stack.
2. Enter the show version command. Output similar to the following is displayed.

NOTE
If any unit in the stack is running an incorrect version of the software, it will appear as non-operational. You
must install the correct software version on that unit for it to operate properly in the stack.

Stack mismatches

When a stack mismatch occurs, the active controller can put any stack member into a non-operational state, which disables all of
the ports except the stacking ports. Stack mismatches can occur for a variety of reasons.
NOTE
After a stack mismatch, the active controller can still download an image to the non-operational unit.
