– The following example shows how to assign WRR weights to each
of the priority queues.
Mapping Layer 3/4 Priorities to CoS Values
This switch supports one 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 number of the TCP port. When these service
is enabled, the priorities are mapped to a Class of Service value by the
switch, and the traffic then sent to the corresponding output queue.
Because different priority information may be contained in the traffic, this
switch maps priority values to the output queues in the following manner:
•
The precedence for priority mapping is IP DSCP Priority, and then
Default Port Priority.
Selecting IP DSCP Priority
The switch allows you to enable or disable IP DSCP priority.
