NBAR is not accepted on a 6509 sub720?

When I try to enable NBAR on a vlan interface I get:

BAR 'protocol-discovery' command cannot be turned on this interface

because of the following reason:

Interface is a LAN port and NBAR/STILE is not supported on LAN

interfaces in PFC3.

When I try to activate it on a tengig interface the command does not exist.

Thx,

Marc

NBAR is not implemented in hardware for the Sup720. So if it was allowed to be enabled, it would severely cripple the switch. You should be able to enable it on FlexWAN interfaces, however.

If you look for NBAR in 65k switches you have to get the Sup 32 PISA:

This card is specifically designed for deep packet inspection (NBAR).
