Client IP

I was wondering if there is a way to find what is the IP address of a client connected on a port on switch 3548. Let's say the client is connected on Port 20.

Thank you.

Re: Client IP

You cannot do it from the switch as it does not maitain a layer 3 table. Do a "sh mac-address-table dynamic" and get the mac address. If you have a upstream router, do a "sh ip arp" from this mac address to get the IP address
