Enable RX Mirroring Filtered
When set, packets that would normally have been filtered are included in the
receive mirroring function and are sent only to the sniffer port. When
cleared, filtered packets are not mirrored.
Note:
Sniffer Port
These bits specify the sniffer port that transmits packets that are monitored.
Bits 7,6,5 correspond to switch ports 2,1,0 respectively.
Note:
Mirrored Port
These bits specify if a port is to be mirrored. Bits 4,3,2 correspond to switch
ports 2,1,0 respectively.
Note:
Enable RX Mirroring
This bit enables packets received on the mirrored ports to be also sent to
the sniffer port.
Enable TX Mirroring
This bit enables packets transmitted on the mirrored ports to be also sent to
the sniffer port.
Switch Engine Port Mirroring Register (SWE_PORT_MIRROR)
This register is used to configure port mirroring.
The Ingress Filtered Count Registers will still count these packets
as filtered and the
(SWE_IPR)
Only one port should be set as the sniffer.
