Direction
For each source port you want to mirror to the destination port, select the direction of the packets
to be mirrored:
•
Tx and Rx— All packets transmitted and received on the source port are mirrored.
•
Rx— Only packets received on the source port are mirrored.
•
Tx— Only packets transmitted on the source port are mirrored.
•
None— No packets are mirrored from this port (default).
The port selected as the Destination Port is greyed-out and unavailable for selection.
Ports that are included as part of a trunk cannot be selected individually as source ports, but
trunks can be selected as source ports.
Note: The Source Port CPU can be mirrored to an external port to debug traffic to and from the
CPU.
