Core switch stacking connection failed
If a switch does not join a stack, look for incompatibilities between the stack master and member switches in relation to the Cisco IOS version, the license levels, and the configuration settings on the switches. Just starting to look at stacking now. This is basically vrrp A Stacked CORE switch is a control plane single point of failure. The first step would be to un-stack them and as you suggested running VRRP/HSRP is probably a good solution. Both x690 switches have the core licence and will do layer 3. Our provider will add our 10 gig ring to our rack and normally they handoff one 10gig fiber to us. The. Moving Firewall, no big issue and we connected it up to the 9000 and it reconncted with the other FIrewall and they connect to eatcher, we move the active firewalls from the firewall connected to the N5K switch to the firewall connected N9K switch.
