    Cisco command to find MAC of device giving same MAC

    I know an IP of a device in a Cisco switch.
    I run this command: sh ip arp
    It gives a list of IP's connected to that switch, but, the hardware address column all have the same MAC address. Why is that? I need it to give the MAC for each of devices, they should be unique?!

    If all the IP addresses are being routed by another router then as the are segmented by layer 3 the MAC wil be the address of the other routers interface that is handling the routing.
