How ASA forwarding traffic to AIP-SSM

[gangadaran86]

Hi All,

Can someone help how ASA device forwarding traffic to AIP-SSM? I'm not taking abt Configuration part like Class-map, policy-map and service policy....want to understand the traffic flow from ASA once traffic matched with ACL to AIP-SSM.

From one of Cisoc document, understood that the module using a Cisco Propietary protocol for communicating with ASA appliance.

================================================================================================================

FYR from Cisco Website:

Q. How does the Cisco ASA AIP-SSM plug into and communicate with the appliance?

A. The Cisco ASA AIP-SSM plugs directly into the SSM slot in the Cisco ASA appliance's chassis. This provides a direct connection to the appliance's backplane. Once the module is installed, a proprietary protocol runs over the bus and controls data flow and messaging between the module and appliance.

Hey ,

as you mentioned above , it uses a cisco Probietary protocol for that communication , there are two interfaces , control channel and data channnel , data channel is where the traffic being forwarded , the backplane is the connection between the ASA and the IPS interface .

Hope that this helps .

Mohammad.

Hi Mohammad,

Thanks for your time and reply.

It means, the data traffic between ASA and AIP-SSM happens in the hardware level ( through Backplane)?
