Check the Enable box to enable 802. 1 p CoS to DSCP remarking for IP packets.
Class of Service (CoS) or 802. 1 p specifies a priority value between 0 and 7 that
can be used by Quality of Service (QoS) disciplines to differentiate traffic.
Differentiated Services or DiffServ is a computer networking architecture that
specifies a simple, scalable and coarse-grained mechanism for classifying,
managing network traffic and providing Quality of Service (QoS) guarantees on
modern IP networks. The DSCP value is the classification value the router uses in
determining the egress marking as the frames traverse and exit the switch.

Configuring 802.1p to Queue Mapping

802. 1 p defines eight different classes of service. To configure 802. 1 p to queue
mapping:
Choose QoS > 802. 1 p > 802. 1 p to Queue Mapping.
For each priority, select the queue mapping corresponding to the service from the
following queue values: Lowest, Low, Medium or High.

Configuring 802.1p CoS to DSCP Remarking

DSCP is a field in an IP packet that enables different levels of service to be
assigned to network traffic. You can assign priorities for the eight different classes
of services in 802. 1 p. To configure 802. 1 p CoS to DSCP Remarking:
Choose QoS > 802. 1 p > 802. 1 p COS to DSCP Remarking.
For each 802. 1 p priority value, enter a priority value (range is from 0 to 63).
Click Save.
