We have setup controllers in a redundant pair Master and Master Standby. This was all working fine but we have to complete an annual check each year to confirm operation. We were completing a test and during the failover tests we experienced an issue with the VLAN in the redundant pair. The Master controller was restarted due a strange issue with a VLAN but now we have a new problem.
The two controllers are in a managment VLAN of 50 with 10.10.0.1 for controller 1 and 10.10.0.2 for controller 2. The controllers cannot ping in each on the managment VLAN but can on any other VLAN configured on the controllers. I have checked the IPSEC and it is not established between the controllers.
But I can ping both controllers from another device in the management VLAN 50. Can I ask if the controllers are in a redundant pair do they only communicate with each other only via the IPSEC tunnel?
When I do a show crypto ipsec sa I can see that the tunnel is not up but I thought a basic ping should have worked
Thanks for any help
