48-6 mls qos scheduler
This command is used to configure the queue scheduling algorithm in global configuration mode. To restore to the
default setting, use the no form of this command.
mls qos scheduler [sp | rr | wrr | wdrr | ets]
no mls qos scheduler
Parameters
48-7 mls qos trust
This command is used to trust either the CoS field or the DSCP field of the arriving packet for subsequent QoS
operation. Use the no form of this command to restore it to default setting.
mls qos trust {cos | dscp}
no mls qos trust
Usage Guideline
The DSCP to CoS map is used by a DSCP trust port to map a DSCP value to an
CoS value. This CoS value is then mapped to CoS queue based on the CoS to
queue map configured by the priority-queue cos-map command.
Example
This example shows how to configure the DSCP 12, 16, 18 to CoS 1 mapping.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#mls qos map dscp-cos 12,16,18 to 1
DXS-3600-32S(config)#
sp Specifies all queues of a port in absolute priority scheduling.
rr Specifies all queues of a port in round-robin scheduling.
wrr Specifies the queues of a port in frame count weighted round-robin scheduling. If the
weight of a queue be configured to zero, the queue is in SP scheduling mode.
wdrr Specifies the queues of a port in frame length weighted round-robin scheduling. If
the weight of a queue be configured to zero, the queue is in SP scheduling mode.
ets Specifies the queues of a port in ETS weighted round-robin scheduling.
Default
WRR queue scheduling algorithm.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 15
Usage Guideline
The user can specify schedule algorithms to WRR, SP, RR or WDRR for the output
queue. By default, the output queue algorithm is WRR (Weighted Round-Robin).
The user may specify the WRR weight by using the wrr-queue bandwidth
command and specify the WDRR weight by using the wdrr-queue bandwidth
command.
The user can also specify the “SP + WRR/WDRR” scheduling mode by configuring
the WRR/WDRR weight of a queue to zero.
Example
This example shows how to configure the queue scheduling algorithm mode.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#interface tenGigabitEthernet 1/0/1
DXS-3600-32S(config-if)#mls qos scheduler sp
DXS-3600-32S(config-if)#
