Hello
is there a way to find out a mapping between physical port on the switch and the IP address of the connected device ?
Thanks & regards

see your arp table..it will show you IP coming through connected port.Hmmm... Here is what I get:
VLAN 1 00:08:5d:82:d1:e4 GE6

Better than nothing but if i could resolve the MAC to IP it would be most useful...
to which port of your device it is connected?
check cdp neighbor.

You could enable DHCP snooping on the switch. That won't show you static IPs, though.

Sorry a bit late responding - no sure how to "enable DHCP snooping" ? Most of our IPs are dynamic so it would be a godd starting point.

Thanks - I believe that with the various pointers you gave me I shall be able to figure out which IP is used on which port.

if yes...
see your arp table..it will show you IP coming through connected port.
if it is DSL modem connected and you want to see the IP...then do "who" or "sh user"
