Extending QoS for MLPPP
Configuring Class-map for Matching MPLS EXP Bits or IP DSCP Value
In this configuration, all MPLS packets flowing through the MLPPP Interface EXP value are matched
and all the IP Packets flowing through the MLPPP Interface IP DSCP value are matched.
Complete the following steps to configure class-map for matching MPLS EXP bits or IP DSCP Values.
SUMMARY STEPS
1. enable
2. configure terminal
3. class-map match-any class-map-name
4. match mpls experimental topmost number
5. match ip dscp [dscp-value...dscp-value]
6. exit
DETAILED STEPS
Step 4
match ip dscp
[
dscp-value...dscp-value
]
Example:
Router(config-cmap)# match ip dscp
af11
Identify one or more differentiated service code point (DSCP), Assured
Forwarding (AF), and Class Selector (CS) values as a match criterion.
• dscp-value—The DSCP value used to identify a DSCP value.
Note In this configuration packets with IP DSCP of value af11 are
matched. Repeat this step to configure more values. If any one of
the values is matched, action pertaining to the class-map is
performed.
Step 5
exit
Example:
Router(config-cmap)# exit
Exits class-map configuration mode.
