Jun 2nd, 2010

Dears,

I would like to do application traffice classification using NBAR,if i configure my router with the following configuration,even it will work without install the pdlm for each protocol,

Router(config) # class-map match-any peer-to-peer

Router(config-cmap) # match protocol gnutella

Router(config-cmap) # match protocol kazaa2

Router(config-cmap) # match protocol napster

Router(config-cmap) # match protocol fasttrack

Router(config-cmap) # match protocol novadigm

Router(config-cmap) # match protocol edonkey

Router(config-cmap) # match protocol bittorrent

Router(config)# policy-map drop-peer-to-peer

Router(config-pmap)# class peer-to-peer

Router(config-pmap)# drop

Router(config)# Interface fastethernet 0/0

Router(config-if)# ip nbar protocol-discovery

Router(config-if)# service-policy input drop-peer-to-peer

I have this problem too.

Hi,

I dont understand what question you want to make? but it seems that you have configured this class-map and want to know whether it will work without PDLM or not ?

So answer is yes...!!

When you create a class map and under it if you match PROTOCOL , it will show you the protocols for which it has the PDLM within the IOS, so you need to require PDLM to be downloaded to router. If any protocol you are trying to match is not listed there than you have to download the PDLM for that protocol to the IOS to use it under class map.

Hope this answers your question..!
