Does Cisco 6509 support NBAR ? do i need a FlexWAN module to implement the NBAR ?
NBAR is only officially supported on the 6500 when using a Sup32 with a PISA card and even then turning on NBAR drastically downgrades throughput.
Even though some of the commands might be available for the Sup720 you should not enable them as this means all packets are then software prcoessed and this will severely affect throughput. NBAR is every CPU intensive hence the reason you don't find it switches.
Netflow would be a much better choice for the 6500 with sup720.
As I understand, you would like to know about the SUP-32 supporting NBAR. NBAR is only supported on sup 32 with PISA not without PISA
These links will give you additional information :
1. Sup32 Pisa supports NBAR and can handle upto 2 Gbps maximum throughput for deep packet inspection .
The PISA is capable of accelerating intelligent services such as NBAR and FPM at 2-Gbps speeds for Internet mix (IMIX) traffic, which is optimal for standard campus access networks of typical enterprises using a pair of Gigabit Ethernet Small Form-Factor Pluggable (SFP) uplinks to each distribution layer switch.
2. Layer 2 NBAR is not supported on Layer 2 interfaces that are configured as part of a service module (such as FWSM and IDSM) when those service modules are configured in inline mode (that is, network traffic is in a direct path through the service module).
FPM and NBAR policies can be applied on any Layer 3 LAN port (routed ports, SVIs, port channels) on the Supervisor Engine 32 PISA. They cannot be applied to WAN interfaces or MPLS VPN/tunnel interfaces.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
