9.0
9.1
The received or transmitted data of any 10/100 port in the ZL50416 chip can be “mirrored” to any other port. We
support two such mirrored source-destination pairs. A mirror port can not also serve as a data port.
9.2
MIRROR1_SRC: Sets the source port for the first port mirroring pair. Bits [4:0] select the source port to be mirrored.
An illegal port number is used to disable mirroring (which is the default setting). Bit [5] is used to select between
ingress (Rx) or egress (Tx) data.
MIRROR1_DEST: Sets the destination port for the first port mirroring pair. Bits [4:0] select the destination port to be
mirrored.
MIRROR2_SRC: Sets the source port for the second port mirroring pair. Bits [4:0] select the source port to be
mirrored. An illegal port number is used to disable mirroring (which is the default setting). Bit [5] is used to select
between ingress (Rx) or egress (Tx) data.
MIRROR2_DEST: Sets the destination port for the second port mirroring pair. Bits [4:0] select the destination port to
be mirrored. The default is port 0.
