Figure 21: Configuring 802.1p-Based Priority
Use the DSCP-Based QoS Mode page to map DSCP values in incoming frames to
QoS values for internal priority processing.
The switch supports a common method of prioritizing layer 3/4 traffic to meet
application requirements. Traffic priorities can be specified in the IP header of a
frame using the six priority bits for Differentiated Services Code Point (DSCP)
service. When these services are enabled, the priorities are mapped to a QoS value
by the switch, and the traffic then sent to the corresponding output queue.
The DSCP is six bits wide, allowing coding for up to 64 different forwarding
behaviors. Based on network policies, different kinds of traffic can be marked for
different kinds of forwarding.
Parameters
