DES-7200 Configuration Guide Chapter 2 QoS Configuration
2-12
Note
This function is not supported. Because it is necessary to associate the
class map with acl, all restrictions of the acl configuration are
applicable for the qos configuration. For the details, see the ACL
Configuration.
2.2.9 Configuring the Output
Queue Scheduling Algorithm
You may schedule the algorithms for the output queue of a port: WRR, SP, RR and
DRR. By default, the output queue algorithm is WRR (Weighted Round-Robin).
You may set the port priority queue scheduling method through the following steps. For
details of the algorithm, see the overview of QoS.
Command Description
DES-7200#configure terminal
Enter the configuration mode
DES-7200(config)#mls qos
scheduler {sp | rr | wrr | drr}
Set the port priority queue scheduling method,
where sp is absolute priority scheduling, rr is
round-robin, wrr is weighted round-robin with
frame quantity, and drr weighted round-robin with
frame length
DES-7200(config)#no mls qos
scheduler
Restore the default wrr scheduling
For example, the following steps set the port output algorithm to SP:
DES-7200# configure terminal
DES-7200(config)# mls qos scheduler sp
DES-7200(config)# end
DES-7200# show mls qos scheduler

2.2.10 Configuring Output
Round-Robin Weight
You may set the output round-robin weight through the following steps:
Command Description
DES-7200# configure terminal
Enter the configuration mode
DES-7200(config)#{wrr-queue |
drr-queue} bandwidth
weight1...weightn
weight1...weightn are the weight values specified
for the output queues. For the count and value
range, see the default QoS settings
