We have two Cat6509 switches as the core in a network distributing L2 VLANs accross Trunk uplinks to non-Cisco edge switches. The trunks have 802.1q and pass extended VLANs. We are seeing a problem with two new VLANs that we created, they appear to be fowarding in STP, but the IP we are running over the VLAN doesn't appear to connect over one particular uplink. This uplink was already in use prior to adding the new VLANs (1050 & 1060) and has been passing VLAN traffic just fine. I added 11050 and 1060 to other trunk uplinks, and we are able to pass the IP without any problem. the interface examples are below:
VLAN 1050 & 1060 do not pass IP

I have already rebooted the edge switch and verified it is running the same code as the other edge switches. It is a Baystack 470.
Any thoughts or suggestions?
