We currently have an existing connection between a 4500 switch and a 2950G. it's a trunk with fiber on the 4500 end and a fiber to copper media converter on the 2950G end. When I move the connection from the 4500 to our 6807 switch with the same config I lose layer 3 connectivity. the trunk is showing up and I can see the 2950G as cdp neighbor from the 6807 but I cannot get to anything hanging off the 2950 or ping the switch itself.
The interface config is fine, I'm more concerned with how routing is configured. Do you have an interface VLAN 2 and/or 33 on each switch? A routing protocol (EIGRP, OSPF) or a default route configured?
Sounds like layer 1 and 2 are good but L3 is failing... Since you're trunking, I assume VLAN's are being used for peering? Can you post the config of the 2950 and the 6807?

The 6807 is our core and handles routing. There is a route to the vlan/network for the devices hanging off the 2950 in the 6807 so it knows how to get there.
