NBAR + BT

[bigeric]

Dear All,

May I know if NBAR can effectively identifiy all BT traffic(or other peer to peer applications).

Can it identify BT traffic if it is not using well-known port ?

thanks

Eric

In Cisco IOS Release 12.3(4)T, the NBAR Extended Inspection for HTTP Traffic feature was introduced. This feature allows NBAR to scan TCP ports that are not well-known and identify HTTP traffic traversing these ports. This feature is enabled automatically when a service policy containing the match protocol http command is attached to an interface.
