6513 MSFC2 & NBAR

Hi,

i'm trying to block peer2peer connections using NBAR on MSFC2.

nbar can recognize and monitor traffic but cannot be able to block it.

i started suspecting of msfc doesn't support blocking traffic with nbar.

6513 has hybrid CatOS/IOS

CatOS8.3(4) on SUP2

IOS 12.2(14)ZA7 on MSFC2

Hi

As per the supporting doc it says that NBAR is supported in MSFC2 with SUP1 or SUP2..

______________________________________________

when i check for policy-map (sh policy-map interface vlan 3), if it matches any packet and police them, it seems nothing matches the policy-map, but i can see traffic with "sh ip nbar protocol-discovery".

also i tried to catch p2p traffic with a route-map and route them to interface null0, but "set interface null0" command is not available :))

if you could help i'll be appriciated

thanks
