how to find out what device connected to a specific port on your hp switch

The easiest way to find a device connected to known specific port is to find the physical address or MAC address first than locate the IP or Name.
To get the device MAC address on the HP switch, issue this command:

HPSwitch1# show mac-address ethernet 4
MAC Address

Note: We issued a command to show the MAC address of the device connected on port 4 of the switch. If you are using multiple module HP switch, you will need to specify the module the port is located. For example; show mac-address ethernet E4, would indicate port 4 of module E.

Once you get the MAC address, the next step is to find associated IP address of the obtained MAC address.
For this, you can use the router, DHCP Server, or MAC Address Scanner tools such as CCGetMAC.

For this example, we will use the router to locate the IP Address of the MAC.

on the router, issue this command:

Router1#show arp | include 000e.7f3d.a488
Internet 3 000e.7f3d.a488 ARPA FastEthernet0/0

Ensure that you are connecting the local LAN interface of the router to get a correct IP address.
