Configuring a Policy-map
Complete the following steps to configure a policy-map.
SUMMARY STEPS
1. enable
2. configure terminal
3. policy-map policy-map-name
4. class class-name
5. priority percent priority-percent -
6. class class-name
7. bandwidth percent bandwidth-percent
8. class class-name
9. set mpls experminetal topmost number
10. class class-name
11. set ip dscp dscp-value
12. class class-name
13. bandwidth percent bandwidth-percent
Step 3
class-map match-any
class-map-name
Example:
Router(config)# class-map match-any
matchdscp
Creates a class map to be used for matching packets to a specified class
and to enter QoS class-map configuration mode:
• class-map-name—Name of the class for the class map. The class
name is used for both the class map and to configure a policy for the
class in the policy map.
Step 4
match mpls experimental topmost
number
Example:
Router(config-cmap)# match mpls
experimental topmost 5
Matches the experimental (EXP) value in the topmost label header.
• number—Multiprotocol Label Switching (MPLS) EXP field in the
topmost label header. Valid values are 0 to 7.
Step 5
match ip dscp
dscp-value
Example:
Router(config-cmap)# match ip dscp
af11
Identifies the DSCP values as a match criterion.
• dscp-value—The DSCP value used to identify a DSCP.
Step 6
exit
Example:
Router(config-cmap)# exit
Exits class-map configuration mode.
