MLS QOS COS
Syntax
mls qos cos <0-7>
Parameters
0-7
Specifies the Class of Service user-priority value. The highest
value is 7 which indicates the highest priority of CoS. The default is
0.
Mode
Interface Configuration mode
Description
Use this command to assign a CoS user-priority value to untagged frames
that are entering the interface specified. By default, all untagged frames
are assigned a CoS value of 0.
Use the no form of the command, NO MLS QOS COS, to return the
interface to the default CoS setting for untagged frames entering the
interface.
The 802.1p priority value on ingress tagged packets are ignored unless
QoS is enabled and CoS is trusted. This means, by default, a priority
tagged packet will egress with the same tag value it was received with, but
the switch will ignore the value.
Confirmation Command
“SHOW RUNNING-CONFIG” on page 166
Examples
The following example sets the CoS priority value to 5 on port 17:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.17
awplus(config-if)# mls qos cos 5
