VLAN ID

[sistemas.p]

Hello all,

I need your help.
I have a Core C4510R catalyst. The problem I have 3 VLANs, and 20 VLAN IDs. Of this VLAN ID I want to know which is the network that is part of them.
Can you help me to understand how IP of the VLAN ID?

THX

Not sure what you are asking but - 

"sh ip int br | inc Vlan"

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

[sistemas.p]

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 :
