How to check the port info connection in a 5500 series switch?

[rdocuyanan]

Hi

I have a catalysts 5509 using CatOS 4.5(4) and the cabling is a lil bit messy now. I have many switches connected to it (3com, and cisco 2900's). My problem is how to check to which port are the traffic goin out. Say in the old inventory I have the data that

one 3com switch is connected to port 2/4 but over time they changed it,

5509(port 2/4)------goin to---(port 1 of 3COM).

Question:

How to verify using show commands in the 5509 CLI

that the 3COM which is indeed connected through port 2/4 of the 5509. Is there a way? given only the

MAC address of the 3COM switch, say the edge switch has no management ip. Even if the edge switch is a cisco with a management IP, I still dont know how to

verify to which port in the core it is connected.

Your help is very much appreciated, so that I dont need to go through the forest of cables.

Thanks

If your looking for a directly connected Cisco device you can simply use 'sh cdp neighbors' (check CDP is enabled at both devices).

If your looking for another device (3com switch) and you know its MAC address you can try

'show cam XX-XX-XX-XX-XX-XX'

where XX-XX-XX-XX-XX-XX is that MAC address.

Hi Jolmo,

I tried it, i noticed that the switch is receiving alot of MAC address from a specified port, I guess this is the normal behaviour.

Thanks

That's beacuse there is a switch or a hub connected to that port.
