How To Find A Device Using Mac Address Racingbda If you are seeing multiple mac address on a trunk port this is a clear indicator that there is another switch hub connected at the other end. you will need to run the sh mac address command at the very edge of your network on the access switches. I am not sure of the model of the switch you are referring too however, on the 3750 the command is sh mac add add (enter the mac add you are looking for).
Learn How Find Device Or Ip Address Using Mac Address In this configuration i will show you how to check port connection of a device using device mac address. Log into cisco switch ping device’s ip address first and find the mac address using show arp | include 99 (note: use include to filter the output) use show mac address table | include 8cce (note: use part of the mac address to filter the result) here, we know that the device is connect to port 9. For a port channel interface, enter the keywords port channel then a number. for a 1 gigabitethernet interface, enter the keyword gigabitethernet then the slot port information. To find the port to which a device with a specific mac address is connected on a cisco switch, follow these steps: 1. log in to the switch. access the switch through ssh or console connection. 2. enter privileged exec mode. you might need to enter the enable password if prompted. 3. show mac address table for the specific mac address.

It depends what kind of switch you are connected to. if the switch is a managed switch, and you know its ip address, run the following command in your terminal. it is then just match the ip with the mac address. If you are already on the edge switch you can run a command "sh mac address table address " and it will give you the port number. incase you get a port which is a trunk port that means the end device does not exist on this switch and exist on some downstream switch. Computers connected to the same tcp ip local network can determine each other's mac addresses. the technology called arp address resolution protocol included with tcp ip makes it possible.
