XCO supports packet mirroring only for the 9920 devices.
Packet mirroring mirrors the whole frame to another egress port. For a frame without the outer tag, the header is terminated and the frame is subjected to further processing, based on ingress and egress configuration.
When mirroring is enabled, one copy of the whole frame is subjected to normal processing where the header is terminated and subjected to regular ingress or egress processing.
Another copy of the frame is mirrored with egress port without any header termination.
The filters for frame that are configured using ingress-group can be applied per port. If the frame does not match the filter, it is dropped.
