Note
MPLS QoS supports all IP QoS commands. Some of IP QoS
commands are shown above, indicating that it has made some
extensions to MPLS QoS.
3.3.1 Configuring Class
Maps
The user can execute "match mpls experimental topmost" command to match
the EXP field in the topmost label of MPLS packets and classify MPLS packets
into multiple service classes by identifying the EXP value. We can configure
different QoS service policies for different service classes (such as traffic
monitoring).
Class Map configuration steps are shown below:
Command Function
DES-7200# configure terminal
Enter configuration mode.
DES-7200(config)# class-map
class-map-name
Create and enter class map configura
tion mode.
Class-map-name is the name of clas
s map to be created.
DES-7200(config-cmap)# match
mpls
experimental topmost
exp-value1 [exp-value2
[exp-valueN] ]
Configure the MPLS EXP value to be
matched; exp-valueN is the EXP value
to be matched; 8 different values can be
matched at one time. This command
only applies to MPLS packets.
DES-7200(config-cmap)# exit
Exit class-map configuration mode.
To delete an existing class map, execute "no class-map class-map-name"
command.
To remove the specified EXP value from a class map, execute "no match mpls
experimental topmost exp-value1 [exp-value2 [exp-valueN] ]" command. This
command can remove all EXP values or partial EXP values at a time.
The following example matches all MPLS packets with EXP value being 2, and
classifies these packets into the class of mpls-exp-2.
DES-7200# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
