Hi everybody,

I have an issue within communicating 2 switches (Cisco 4500 and 6500), i have enabled cdp to both switches but then when i run the "show cdp neighbors" i can´t see the link between them.

There are 2 vlans configured on each connection, one for each interface and therefore switche´s interfaces connected to each other have been set as switchport access for each vlan in both sides.

does anybody know what's wrong and why can't i see those connections??
