Stacked switches has no Back-up configured: How to?


I would just want to ask how to configure back-up role in switches configured as stacked. See below output:

Hello James

The command is configure stacking redundancy minimal

Let me know if that helps answer your question
I am having the same issue...i have 2 x670 + 2 x460 configured in a stack. initially i had a master, backup and two standby, but now when i look at the stacking i am seeing two Masters and two standby.

@Paul R will this command "configure stacking redundancy minimal" solve the dual master issue? After rebooting the stack, it went back to master + backup but i am afraid it will happen again.

Hi Paul,

Thanks for the reply. configure stacking redundancy minimal + reboot did the trick.
