So today I was busy trying out a route-map on our core switch stack of X6 3650's.
It wasn't doing what I wanted it to do, so deleted the access list that the route-map related to. Within this ACL were a source and IP address for hosts with no relationship to the ssh connectivity to the device.
As soon as I hit enter I lost connectivity to the switch and the entire business lost access to all services, everyone lost connectivity to file servers etc etc. I couldn't ping any layer 3 interface on the switch from any source, but other switches with layer 2 connectivity could see it up and active via CDP.
Unfortunately our datacentre is remote so after realising there was no way onto the switch despite quite a few redundant paths, i asked for the entire stack to be power cycled.
15 minutes later the stack had rebooted and access was restored.
Has anyone else had this from such a simple innocuous command? It seems like the switch completely locked up for no apparent reason
