From what interface does an ASA firewall re-directs traffic to the SFR module ?

I tried to find alot for the answer of this question online, but nothing has helped much.

 

I am aware that the SFR module shares the MGMT interface with the ASA and its only used for Management level communication to the FMC.

But what interface on the SFR module is used to receive traffic from ASA ?

Apologies, if this question sounds very silly.

Hi There,

 

The packets transfer from ASA to SFR is done via internal interface which is  controlled by system and cannot be modified. The mgmt interface (shared with ASA physical interface) is only used for external communication and its manager.

ASA just needs to be configured with proper service policy and ACL to redirect traffic to SFR. All internal comm is done via control plane and dataplane if you want to capture traffic there.

 

Hope it helps,

Yogesh
