4. set cos cos-value
DETAILED STEPS
Command or Action
Step 1 configure terminal
Example:

switch(config)#
Step 2
policy-map [type qos] [match-first] [qos-policy-map-name

switch(config-pmap-qos)#
Step 3 class [type qos] {class-map-name | class-default}
[insert-before before-class-name]
Example:
switch(config-pmap-qos)# class class1
switch(config-pmap-c-qos)#

Purpose
Enters global configuration mode.
Creates or accesses the policy map named
qos-policy-map-name, and then enters policy-map mode.
The policy-map name can contain alphabetic, hyphen, or
underscore characters, is case sensitive, and can be up to
40 characters.
Creates a reference to class-map-name, and enters
policy-map class configuration mode. The class is added
to the end of the policy map unless insert-before is used
to specify the class to insert before. Use the class-default
keyword to select all traffic that is not currently matched
by classes in the policy map.
Sets the CoS value to cos-value. The value can range from
0 to 7.
