IP NBAR on Mutliple 802.1q VLANS

Unanswered Question
Feb 8th, 2009

Dear All

Just got a quick question, and hoping someone can help with a quick answer or a suggestion on how it can be done.

Basically we have one router with one WAN interface with 5 VLANS. I enabled ip nbar on the WAN and can see the break down of each type of packet and protocol.

Now the question is, will it be possible to break it down on different VLANS?

Reason for this is because each VLAN is assigned to a different customer and each customer wants a break up of their usage.

Any replies or suggestions will be much appreciated.

I have this problem too.

Hello John,

are you interested on filtering the NBAR show commands on a per Vlan basis ?

I ask because for me it's not clear what you mean with

breaking down on a vlan basis

Hope to help

Hi Giuseppe

Thanks for the reply, basically we have for example 5 customers on 5 different vlans sharing on link.

I enabled NBAR on the WAN interface and i can see what protocol and traffic is going through for example like HTTP, P2P etc.

What i want to do is get NBAR to work on each individual VLAN.

So i can provide each of the 5 customers a report showing what protocols and traffic they are using.

I hope that makes it more clear :)
