Hello!
I have a Catalyst 9410 chassis in the ACCESS LAYER - L2 ONLY - with DUAL SUPs. BUT, I only have the DNA Essentials and the Network Essentials licenses, NOT the Advantage license, so that means I do not have some HA functionality like NSF or ISSU. Is that a deal breaker?
What supporting technologies and features MUST be deployed, if any, in a DUAL SUP chassis just to have a failover if the active SUP goes down? In other words, if I have DUAL SUPs, does that mean I MUST configure NSF and SSO to get failover? Or is simply having the DUAL SUPs in the chassis enough to get the failover to work if the active SUP goes down?
