IP Address for the switch port

Hi all,

Is there any way to find out ip address of the PC connected to particular switch port ?

Re: IP Address for the switch port

Hi Rajesh,

There is no easy way to do so. This switch only monitors and records the MAC addresses observed on each port. If it is a layer 3 switch, then you can possibly observe the entries in the ARP cache to see which IP address maps to which MAC address.

Hope that helps - pls rate the post if it does.

Paresh,

If you issue sh ip arp on layer 3 switch it is only listing the ip for the virtual vlan interfaces only not physical ports ?

'sh arp' on a L3 switch will show you the IP->MAC mappings for all devices that the switch has had to do ARP resolution for. This certainly does include physical ports to which hosts are attached.
