QoS > 802.1p Default Priority

RX (receive) mode: Duplicates the data that send to the source and forwards it to the Target Port.

Both (transmit and receive) mode: Duplicate both the data transmitted from and data send to the source port, and forwards all the data to the assigned Target Port.

None: Turns off the mirroring of the port.

QoS > 802.1p Default Priority

This feature displays the status Quality of Service priority levels of each port, and for ports that are Untagged, the priority can be adjusted.
