3.3.2 Configuring Policy
Maps
The user can configure different QoS service policies for different service
classes (such as traffic monitoring, EXP remarking, etc).
Policy Map configuration steps are shown below:
Command Function
DES-7200# configure terminal
Enter configuration mode.
DES-7200(config)# policy-map
policy-map-name
Create and enter policy map
configuration mode; policy-map-name
is the name of policy map to be
created.
DES-7200(config-pmap)# class
class-map-name
Create and enter data classification
configuration mode; class-map-name
is the name of class map created
already.
DES-7200(config-pmap-c)# set
{ ip dscp new-dscp | cos new-cos
[none-tos]}
Set new ip dscp value or new cos
value for IP packets in the traffic; the
new ip dscp configured won't apply to
non-IP packets.
New-dscp is the new DSCP value
configured; the value range differs from
product to product.
New-cos is the new CoS value to be
configured, with range being 0-7.
None-tos means to configure new CoS
value without modifying the DSCP
value of packets.
