Re: VLAN ID

Hello,

 

unless there is some sort of layer 3 interface configured for your VLANs, there is no link between the Vlan ID and the assigned IP address space. I guess the best you could do is list the mac addresses in a Vlan and compare them with the ARP table:

 

show mac address-table vlan x

show arp vlan x

Re: VLAN ID

Hi Georg,

 

from show mac address-table vlan 151 gives me the whole table of the MAC. But when I do them a: show arp vlan 151 to see the ip tells me error :
