To do… Use the command… Remarks
3. Configure the interface or interfaces
to use the 802.1p priority in
incoming packets for priority
mapping
qos trust dot1p
Required.
By default, the switch does not
use the priority in incoming
packets, but the priority of the
receiving port as the 802.1p
priority of the incoming
packets.
4. Return to system view
quit —
5. Enter priority mapping table view
qos map-table dot1p-lp —
6. Configure the priority mapping
table to map the specific 802.1p
priority values to a local
precedence value
import import-value-list export
export-value
Optional.
For information about the
default priority mapping tables,
see the ACL and QoS
Configuration Guide.
For more information about the 802.1p priority, priority trust mode, and port priority, see the ACL and
QoS Configuration Guide.
For more information about the qos trust dot1p, qos map-table, and import commands, see the ACL and
QoS Command Reference.
Configuring WRR queuing

queuing is enabled on ports.
4. Add the specific queue to WRR priority
group 1 and configure the scheduling
weight for the queue
qos wrr queue-id group 1
byte-count schedule-value
Optional.
By default, the scheduling
weights of queues 0 through
7 are 1, 2, 3, 4, 5, 9, 13,
and 15.
For more information about the qos wrr and qos wrr byte-count commands, see the ACL and QoS
Command Reference.
Configuring PFC parameters
To avoid dropping packets with a certain 802.1p priority, you can enable PFC for the 802.1p priority and
this feature helps reduce the sending rate of packets carrying this priority when network congestion
occurs.
