If an Ip address conflict occurs ,Is there any way (command) to find out from the Switch , that the conflicted Ip address (PC) are connected to which port on that Switch .

Hi Sudeesh,

There is no direct command which can let you the port number on a switch but definetely there is way. If you know the conflicting ip address then you can go to the first layer 3 device or first layer 3 hop for that network and do "sh ip arp " and get the mac address and once you get the mac address you can come back to that switch and run a command "sh mac-address-table address " and get the port detail.
