We were trying to configure a pair of Clean Access Servers in High availability mode and are having some problems.
The primary server was working properly in an In-band Virtual gateway mode, we followed the instructions to add the failover settings to it and used a new service ip (same for trusted and untrusted interface for virtual gateway mode). After rebooting we had contact with the server for a few minutes and then lost it completely, the server is still on but we cannot reach it through the network.
The switch where it is connected is giving the following error:
CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on FastEthernet7/0/7 (999), with SW_VOZ_DATOS_P33 FastEthernet8/0/3 (998)
Per configuration guide we do have a different native vlan on the ports where the trusted and untrusted interface from the CAS are connected to.
Only the primary CAS is connected at the time, but I understand we should be able to have connectivity with it.
Is there something else needed to configure the CAS in virtual gateway mode and high availability??
Thanks and regards,
