I have a new Catalyst 4500X switch. I have the basic config on it, with ports configured as trunks, with nonegotiate. When I plug the switches in, the ports come up and CDP shows my neighbors. However, when I try to ping the other switches, it won't go through. IP Default-Gateway is setup, but I'm not sure what else I'm missing. Is there something on a 4500X switch that is different than a 3560 or 3560X switch? Shouldn't it start forwarding packets as soon as a trunk is established? All my VLANs are up too.
I see the following config:
interface Vlan117 ip address 10.1.17.32 255.255.255.0 ip helper-address 10.1.1.71 ! ip default-gateway 10.1.1.1 ip forward-protocol nd no ip http server
whats the ip address are you trying to ping the other end?
