Routing in 4908G-L3

Connected to 4908G-L3 are two 3524XL switches with fiber jumpers.

Connectivity is sporadic. Sometimes both are connected, sometimes just one or the other end is connected. Routing has never occured. We have configured port-channel subinterfaces, encapsulated with dot1q (even tried ISL). Show ip route and show cdp neighbor shows all directly connected device interfaces. Please help if you know anything about 4908 layer 3 switches. Thanks!

Re: Routing in 4908G-L3

Do you have the "no negotiation auto" under the gig interfaces? Copy/paste the relevant configurations from both the 4908G-L3 and the 3524XL. Also refer to the following page for sample configs
