Using Cisco Network Assistant... Can I find out the IP of a host which is connected to port 6 in my Catalyst 2960-24TC...

Many thanks in advance...

Try this: 

conf t

ip device tracking

interface range g0/1 - 24

ip device tracking max 10

end

wr

-- Wait for 15 seconds --

Command:  sh ip device tracking

or if you know what interface, "sh ip device tracking interface ".

Please don't forget to rate our useful posts.  Thanks.

There is really no easy way to discover the IP address of the device connected to a port.

1. If  you can get the MAC address of the device by using the 'show mac-address-table' command.  Once you have these, you can do:

- if the switch is a L3 switch, issue the command 'sh ip arp'or '"show ip arp | include "' to see if the MAC address is one that has been resolved recently.  In that case, the IP address associated with that MAC address is the IP of the device connected to that port.

2. You can also download a freeware tool, ccgetmacaddress, with this tool you can get the IP to MAC or MAC to IP.

Hope it helps.

Sandeep,

Try the "ip device tracking" feature.  It'll pick up the IP addresses very easily, including 169.X.Y.Z.
