Cisco RV220W Administration Guide
802. 1 p QoS provides a mechanism for implementing QoS at the Media Access
Control level. By enabling 802. 1 p CoS to DSCP remarking, the router can set the
DSCP field in IP packets, according the eight different classes of services in
802. 1 p.
To configure 802. 1 p:
Choose QoS > 802. 1 p > 802. 1 p Configuration.
Check the Enable box to enable 802. 1 p QoS.
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.
