CSM VLANs down on 6513

[Patrick Colbeck]

Hi

I configured a CSM for a customer on a 6513 a couple of weeks ago and it worked fine. It's configured in routed mode with a client and server VLAN. There are no clients on the client VLAN and no servers on the server VLAN as they are all mutilpe hops away.It's not in prodcution yet as they want to do some testing.

Today I got an email saying taht it had stopped working and when the client looked at the 6500 both the client and server VLANs showed as down.

To fix it he recreated the VLANs on the CSM module and it all burst into life. Unfortunatley they don't have suslog on the 6500 so there is no record of any errors.

Has anyone seen anything like this before ?

Thanks

Pat

Hi Pat,

This problem description is too vague to comment on. Would help to know:
-version of chassis IOS and CSM code.
-relevant configuration snippet.
-for 'when looked at 6500 both client & server VLANs showed down':
    -what command(s) showed this?
    -provide actual output seen here?
-for 'it stopped working':
    -what type of traffic was it? LB or pass through?
-did this config disappear or did they do delete/recreate?

Best regards.
