Catalyst 5500

Hello,

On a 5500, if I ping an IP address and do a show arp, it returns the MSFC information. What I am looking for is the port for the IP address I am pinging, not the MSFC. How can I obtain this information?

Regards,

The reason you mite be seeing the mac address of the msfc , cos you must be pinging outside the network in which the switch ip resides. Is the ip address you are pinging and switch is in the same network..

Yes, the IP I am pinging and the switch are in the same network.

I know with the Catalyst 6509, it will give you the mod/port of the ip you are pinging when you do a show arp xxxx.xxxx.xxxx.xxxx.

However, the 5500 does not have this capability and I don't remember the command to get the mod/port of what I am pinging.

other option , ping it from the default gateway, get the mac address and then find out what port the switch is learning the mac add

Ok, I will try that, thank you!!

Sorry, exactly what commands would I use to do this, could you give me an example? Thanks again!

Hi,

You can run "show cam " command once you got mac address of the server.

To get mac address from Window,

ping the server then run "arp -a "

To get mac aadress from linux,

ping the server then run "/sbin/arp ".

I hope this helps :)
