Hello, I ran into a weird situation today that I’m unsure of how to proceed with.

Due to a power failure we lost power to 3 of 4 switches in a Cisco 9300 Stack. At 10:57am yesterday in the event log of this switch I can see the OperStatus of the Stack Ports go down. I have an alert configured against the status of “Switch Stack Failure” does not equal OK. However this alert did not go off at the time of the outage, it has for other switch stacks though.

Then at 5am this morning the logs of the device indicate it went through and essentially removed switches 2-4 of this stack.

We are currently running 20.7.10549. I know we need to update, but our linux team has not gotten around to it.

Is there anyway to look into this?
