Re: ip tracking

Hi,

If i understand you correct, you want to know the IP address connected to a switchport.

From the network router do "show arp", and on the switch do "sh mac-address-table".

And map, the MAC to IP to the switchport using the output you've got.

hi

thank u 4 ur good idea I loged on my switch & I given command "sh mac-address-table" then it was showing all macadds & ports but what is the next command shall I give to get IP of the particular port

Re: ip tracking

Hi,

Take the MAC address attached to that specific switchport from the switch output, copy it and then access your network router and then by using "show ip arp | i " and you'll get the IP address.

P.S Jon has stated it nicely too.

Re: ip tracking

Hi

Could you clarify what you want.

if you want to find out what the Ip address of a client attached to your switch is you need to first look at switch mac address table.

Find the mac address attached to the port then go onto the nearest layer 3 device and do a "sh ip arp | include "
