Command Line Interface
Command Usage
WRR controls bandwidth sharing at the egress port by defining scheduling
weights.
Example
The following example shows how to assign WRR weights of 1, 3, 5 and 7 to the
CoS priority queues 0, 1, 2 and 3:
Console(config)#queue bandwidth 1 3 5 7
Console(config)#

queue cos-map

Use this command to assign class of service (CoS) values to the priority queues
(i.e., hardware output queues 0 - 3). Use the no form to set the CoS map to the
default values.
Syntax
queue cos-map queue_id [cos1 ... cosn]
no queue cos-map
queue_id - The ID of the priority queue.
Ranges are 0 to 3, where 3 is the highest priority queue.
- cos1 .. cosn - The CoS values that are mapped to the queue ID. It is a
space-separated list of numbers. The CoS value is a number from 0 to 7,
where 7 is the highest priority.
Default Setting
This switch supports Class of Service by using eight priority queues, with
Weighted Round Robin queuing for each port. Eight separate traffic classes
are defined in IEEE 802.1p. The default priority levels are assigned according
to recommendations in the IEEE 802.1p standard as shown below.
