Chapter 26 | Quality of Service Commands
– 650 –
To create a service policy for a specific category of ingress traffic, follow these steps:
1. Use the class-map command to designate a class name for a specific category
of traffic, and enter the Class Map configuration mode.
2. Use the match command to select a specific type of traffic based on an access
list, an IPv4 DSCP value, IPv4 Precedence value, IPv6 DSCP value, a VLAN, a CoS
value, or a source port. Note that a class map can include match settings for
both IP values and a VLAN.
3. Use the policy-map command to designate a policy name for a specific manner
in which ingress traffic will be handled, and enter the Policy Map configuration
mode.
4. Use the class command to identify the class map, and enter Policy Map Class
configuration mode. A policy map can contain up to 16 class maps.
5. Use the set cos or set ip dscp command to modify the per-hop behavior, the
class of service value in the VLAN tag, or the priority bits in the IP header (IP
DSCP value) for the matching traffic class, and use one of the police commands
to monitor parameters such as the average flow and burst rate, and drop any
traffic that exceeds the specified rate, or just reduce the DSCP service level for
traffic exceeding the specified rate.
6. Use the service-policy command to assign a policy map to a specific interface.
Note: Create a Class Map before creating a Policy Map.
class-map This command creates a class map used for matching packets to the specified class,
and enters Class Map configuration mode. Use the no form to delete a class map.
