Hi All ,

Is there any command in switch which shows all the ip address alloted to the computers attached with the switch or ip address alloted for computers under particular VLAN .

I have this problem too.

Hi Nilesh,

There is no such direct command to get the desired output.

But if you can note down the mac addresses which are learned on switch from the switch cam table "sh mac-address-table dynamic" you can go to your first hop router and issue a command "sh ip arp " to find the ip address associated to that mac address.

Hi

if the switch is running as a L3 switch then you could use sh ip arp vlan #

sample output would look like;

Protocol Address Age (min) Hardware Addr Type Interface

Internet x.x.x.155 8 0011.4322.ec91 ARPA Vlan1

Internet x.x.x.152 0 Incomplete ARPA

However if the switch is running at L2 only you cannot view IP addresses of attached host; you can only view mac's of the hosts.

with #sh mac-address-table dynamic vlan #

Thanks
