Our Service Provider runs a 7609 and has Q in Q tunneling to provide us L2 vlan services over a MM Fiber link.
We have a 4006 on 12.2.25 (EWA9) with a 6 port Gig blade WS-X4306-GB and are trying to establish connectivity on the link, but the conenction remains in down/down state, regardless of the configuration changes we have tried (speed nonegoiate, flowcontrol send/receive on/off, switchport mode trunk/desirable/auto).
Oddly, the same Gbic and fiber feed, connected into a Cisco 3550 switch comes up with no problem.
Below are the configurations of the Service Providers 7609, as well as the configuration of the 3550 (which worked), and the configuration we tried on the 4006.
Please review and advise of any problem you see in the configurations.
Thanks,
-Scott
