Cluster Expressway C and Expressway E

Hi all,

 

I have C1 clustering with C2 and E1 clustering with E2.

For traversal zone, C1 and E1 is active as shown below.

 

1) It works perfectly to E1 and E2.

2) But for C2, it gives me the error message say " the host is no response from the system. Before i make it cluster with C1, the Traversal Zone between C2 and E2 is works fine and reachable. After clustering, and i got this error message.

For the possible works around:

- I did check the certificates for the traversal connection.

- I did update the crt between C2 and E1 and E2. Check for the SSH tunnel between C2 to E1 and E2 is works fine.

Can you guys please guide me, is there any others my configuration problems?

 

Appreciate for your help.

 

Regards,

Re: Cluster Expressway C and Expressway E

Did you check if the warning is correct? after the cluster setup E2 is still reachable from C2?

By the way check the event log and the network log (Status -> Log) for more information and do a tcp dump from all the cluster member (Maintenance -> Diagnostic logging *Take tcpdump while logging*) and compare them.

Hi Sandro,

Thanks for your reply, I already solved this question by open TAC, and seems like i already make wrong understanding about clustering of Expressway C and E.
