Solved: Catalyst 2960s Stacking with different IOS versions

fuhrersk8 · ‎02-11-2014

Hello Forum Team;

When adding a new switch with older ios version to an existing stack (flexstack) does the new switch will be able to join the stack?

Thanks in advanced!

Hi,

In a stack/flexstack all the switches should have exact same IOS version, otherwise there will be a version mismatch on the stack and the new switch will not be able to join the stack.

Hi, if your switch is 2960s you can add to stack, and your stack has the future of auto-upgrade to upgrade all the switches in the stack and make the ios equal.
