29.4.10.4 Port Mirroring
The function allows duplicating traffic to a dedicated mirror port. Any one of the ports can
be assigned to act as a mirror port (register MIRROR_CONTROL).
The mirror port then is always added to the list of output ports and therefore receives a copy
of the frame, if any of the following rules matches with the currently processed frame:
In addition, a counter is implemented (Register MIRROR_CNT) that allows specifying that
only every Nth frame that matches any of the above criteria is mirrored. If the counter is
set to 1 or 0, every frame is mirrored that matches any of the above criteria.

• Ingress Port Number Match
• Egress Port Number Match
• MAC Ingress SA Match
• MAC Ingress DA Match
• MAC Egress SA Match
• MAC Egress DA Match
When a frame is received on port N and the corresponding bit in the register
MIRROR_ING_MAP
When a frame is forwarded to port N and the corresponding bit in the register
MIRROR_EG_MAP
When the Ingress Port Number match succeeded (see above) and the MAC source
address matches the MIRROR_ISRC, the frame will be mirrored.
When the Ingress Port Number match succeeded (see above) and the MAC destination
address matches the MIRROR_IDST, the frame will be mirrored.
When the Egress Port Number match succeeded (see above) and the MAC source
address matches the MIRROR_ESRC, the frame will be mirrored.
When the Egress Port Number match succeeded (see above) and the MAC destination
address matches the MIRROR_EDST, the frame will be mirrored.
