Remarking and the CoS to Q map
Example
For policy-map
pmap3
and class-map
cmap1
, set the CoS value to
2
and also set
the input to the CoS to queue map so that the traffic is assigned to egress queue 1:
awplus#
configure terminal
awplus(config)#
policy-map pmap3
awplus(config-pmap)#
class cmap1
awplus(config-pmap-c)#
remark new-cos 2 both

Commands
mls qos map cos-queue to
show mls qos maps cos-queue
The above mapping is set by the command,
mls qos map cos-queue to
, and displayed by the command,
show mls qos maps cos-queue
. With the
remark new-cos
command unset, or set to
external
, the queue mapping
takes its input from the Existing CoS value. With the
remark new-cos
command set to
internal or both
, the
queue mapping takes its input from the value set by the command,
remark new-cos
. Note that although the
CoS to Queue map applies to the whole switch, the
remark new-cos
command applies per individual class-map.
