Link Status on Campus Manager For Q-in-Q Links

Unanswered Question
Jan 15th, 2009


We have a customer with Cat6500 VSS chassis configured with Etherchannel 802.1Q-in-Q links between Edge & Distribution switches. The distribution end of the link is configured as an IEEE802.1Q tunnel port whilst the Edge end of the link is an IEEE802.1Q trunk port (assymmetrical link).

CDP is automatically disabled for this configuration so link status on campus manager doesn't work correctly. If we enable CDP on the links then we get "native vlan mismatch" error messages. Is there a way around this other than filtering/ignoring the messages?

I have this problem too.

You might try asking about this on the LAN switching forum. Enabling CDP is the only way to get the links to show up on the Topology Map, but I am not sure what, if anything, can be done to avoid the mismatch messages.
