Priority (0-7) This parameter is specified if you want to re-write the 802.1p default priority previously set in the
Switch, which is used to determine the CoS queue to which packets are forwarded. Once this field
is specified, packets accepted by the Switch that match this priority are forwarded to the CoS
queue specified previously by the user.
Replace priority with
−
Click the corresponding box if you want to re-write the 802.1p default priority
of a packet to the value entered in the Priority field, which meets the criteria specified previously in
this command, before forwarding it on to the specified CoS queue. Otherwise, a packet will have its
incoming 802.1p user priority re-written to its original value before being forwarded by the Switch.
For more information on priority queues, CoS queues and mapping for 802.1p, see the QoS
section of this manual.
