Aivars.

I haven't heard something regarding NBAR & H323, but another day at a Cisco QoS Bootcamp,
talking with some dudes I listen a report about NBAR displaying NETBIOS as Kaaza and a path, 
not a IOS release, that would fix it. Have you opened a case at the TAC about your NBAR issue ?
Have someone from the list some previous experience or knowledge regarding NBAR mismatch 
information, bugs, and paths/bugs fixes ?

Yours Truly.

Assunto: [c-nsp] NBAR and H323


In order to limit p2p for the customer who owns a residential network
we have placed Cisco 1812 at the edge and deployed nbar. This is a
test installation. I am very pleased with the router performance but
am getting strange protocol pattern. H323 is always at the first
place. There is only 1 known ATA in the network the rest are PCs. Has
anybody seen something like this? Is Cisco wrongly detecting the
protocol or some application is masking under h323?

IOS 12.4(4)T
