Traffic Classes Defined: Example
In the following example, two traffic classes are created and their match criteria are defined. For the first
traffic class called class1, ACL 101 is used as the match criterion. For the second traffic class called
class2, ACL 102 is used as the match criterion. Packets are checked against the contents of these ACLs
to determine if they belong to the class.
class-map class1
match access-group ipv4 101
exit
!
class-map class2
match access-group ipv4 102
exit
Use the not keyword with the match command to perform a match based on the values of a field that are
not specified. The following example includes all packets in the class qos_example with a DSCP value
other than 4, 8, or 10.
class-map match-any qos_example
match not dscp 4 8 10
!
end
Traffic Policy Created: Example
In the following example, a traffic policy called policy1 is defined to contain policy specifications for
the two classes—class1 and class2. The match criteria for these classes were defined in the traffic classes
created in the
“Traffic Classes Defined: Example” section on page 33.
For class1, the policy includes a bandwidth allocation request and a maximum byte limit for the queue
reserved for the class. For class2, the policy specifies only a bandwidth allocation request.
