Have got a strange issue on hands, scenario: Edge - 2900, Core - 4500. 8 VLANS on core, 3 VLANS on edge(data,voice,management, VLAN1 is not the management VLAN). Trunks are okay but when I move the ports to a different data VLAN, cannot ping anything from the new VLAN ports,which I created. Suggestions......
I assume here that the 4500 is doing the IP routing.
If you have created new VLANs (which these ports are put into), Did the VLANs info propagate through both switches? In other words, do you see the VLANs when you issue the command show vlan on both switches?
If so, did you set an IP address for the VLAN interface on the core? if not, you have to, since it acts as the gateway IP (unless the VLAN is connected to a real router offcourse).
