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.
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 .
Thanks for your time and reply.
It means, the data traffic between ASA and AIP-SSM happens in the hardware level ( through Backplane)?
