Embedded Packet Capture (EPC) on Cisco4510R-E - Cisco IOS: What packets are punted to CPU?

Hi there,

I have a Cisco WS-C4510R-E (MPC8548) running cat4500e-ipbasek9-mz.152-2.E8.bin image.  I want to do an embedded packet capture on an interface. I'm aware whatever packets I capture will be sent to the CPU.

 

However, I'd like to know exactly which packets will be sent to the CPU.  I will be applying an ACL filter.  Will it be:

 

a) all packets from the interface I configure as the capture point (and then the ACL filters afterwards)

b) the packets that match my ACL

 

The reason I ask is because in the EPC Wireshark feature for IOS-XE the packets that are sent to the CPU can be filtered using the 'match' command.  There is a filter command as well which only filters AFTER the packets are sent to CPU.

 

So i just want to know whether it's similar for the Cisco IOS EPC.  Hope that makes sense.

I've actually just proved b) to be correct by testing.  I will close thread.
