I'm trying to teach myself how to manage and configure our Cisco switchs. I'm more familar with 3COM switchs. What I want to find out is how to determine the IP address of the PC/Printer attached to each port of our switchs. With the 3Com it's very easy. Can this be done on the 2924-XL? If so how? (Please provide detailed instruction. So far, the instructions provided by Cisco have been "Greek" to me.)
because the switch is a layer 2 device you cannot get the IP addresses of attached pcs/printers directly off of the switch. But you can get the mac address of the device by doing a "show mac fa0/X" where X is the port number. then i go to the router(assuming Cisco)
and do a "sh ip arp xxxx.xxxx.xxxx " where the x's are the MAC address of the device, and the router should return the IP address.
if the switch management interface is in the same vlan as the clients (by default) and if you want to find out which port a specific ip address device is connected, then ping from the switch and get the mac address and check using the mac-address table.
