Catalyst 3750 switch gettign IP of a port 1

[Seegee]

Is there a command I can use to get the IP address assigned to a specific port on a catalyst 3750?

I don't know the MAC address for the device that is connected to that port.

If you have L3 routing enabled, you can see all the IP addresses of the devices communicating with the switch using the 'show arp' command. This command also shows the associated MAC addresses of each device which you can then double-check against the 'show mac-address-table' command to see which port they are on.

If the 3750 is just being a switch, you won't see many resolved IP addresses in there. You may need to look at its default gateway router device and see what the resolved IP address/MAC address is there instead.

If it is a single subnet on the switch you can sometimes ping the broadcast address 255.255.255.255 and it will populate the arp and mac table and you can line them up that way .
