I am attempting to deploy a new environment and I have a fresh ICX 7150 stack (two switches) that are having problems.
I don't know if I have a bad unit so I wanted to check with the community to see if anyone else has stacked switches on 8.0.92 or 8.0.92c.
First, once the stack is created, and after a period of a few hours, I can no longer configure the stack using the SmartZone 100. I get "Switch configuration update failed" alarms.

Hi Steven,

Thanks, we need to debug this to see what actions are getting failed. The tac engineer will share the next action plan.

Ruckus support was able to identify that using a "Linear" topology when stacking ICX switches is not currently compatible with the SmartZone controller. A "Ring" topology must be used.
