Configuring Quality of Service Parameters
To create a service policy for a specific category or ingress traffic, follow these steps:
1. Use the “Class Map” to designate a class name for a specific category of traffic.
2. Edit the rules for each class to specify a type of traffic based on an access list, a
DSCP or IP Precedence value, or a VLAN.
3. Use the “Policy Map” to designate a policy name for a specific manner in which
ingress traffic will be handled.
4. Add one or more classes to the Policy Map. Assign policy rules to each class by
“setting” the QoS value to be assigned to the matching traffic class. The policy
rule can also be configured to monitor 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.
5. Use the “Service Policy” to assign a policy map to a specific interface.
Configuring a Class Map
A class map is used for matching packets to a specified class.
Command Usage
• To configure a Class Map, follow these steps:
- Open the Class Map page, and click Add Class.
- When the Class Configuration page opens, fill in the “Class Name” field, and
click Add.
- When the Match Class Settings page opens, specify type of traffic for this class
based on an access list, a DSCP or IP Precedence value, or a VLAN, and click
the Add button next to the field for the selected traffic criteria. You can specify up
to 16 items to match when assigning ingress traffic to a class map.
• The class map is used with a policy map (3-204) to create a service policy (3-207)
for a specific interface that defines packet classification, service tagging, and
bandwidth policing. Note that one or more class maps can be assigned to a policy
map.
