Chapter 1 CLI Command Reference
set cos
You can do the same for the DSCP marking category. That is, you can configure the
set cos dscp
command, and the DSCP value will be copied and used as the CoS value.
Note
If you configure the
set cos dscp
command, only the
first three bits
(the class selector bits) of the DSCP
field are used.
Examples
In the following example, the policy map called “cos-set” is created to assign different CoS values for
different types of traffic. This example assumes that the class maps called “voice” and “video-data” have
already been created.
Router(config)#
policy-map cos-set
Router(config-pmap)#
class voice
Router(config-pmap-c)#
set cos 1
Router(config-pmap-c)#
exit
Router(config-pmap)#
class video-data
Router(config-pmap-c)#
set cos 2
Router(config-pmap-c)#
end
Enhanced Packet Marking Example
In the following example, the policy map called “policy-cos” is created to use the values defined in a
table map called “table-map1”. The table map called “table-map1” was created earlier with the
table-map
(value mapping) command. For more information about the
table-map
(value mapping)
command, see the
table-map
(value mapping) command page.
In this example, the setting of the CoS value is based on the precedence value defined in “table-map1”:
Router(config)#
policy-map policy-cos
Router(config-pmap)#
class class-default
Router(config-pmap-c)#
set cos precedence table table-map1
Router(config-pmap-c)#
end
