Step 3
match {access-group acl-index-or-name |
ip dscp dscp-list | ip precedence
ip-precedence-list}
Define the match criterion to classify traffic.
By default, no match criterion is defined.
Only one match criterion per class map is supported, and only one ACL
per class map is supported.
• For access-group acl-index-or-name, specify the number or name
of the ACL.
• For ip dscp dscp-list, enter a list of up to eight IP DSCP values to
match against incoming packets. Separate each value with a space.
The range is 0 to 63.
• For ip precedence ip-precedence-list, enter a list of up to eight
IP-precedence values to match against incoming packets. Separate
each value with a space. The range is 0 to 7.
Step 4
exit Return to class-map configuration mode.
Step 5
exit Return to global configuration mode.
Step 6
class-map [match-all | match-any]
class-map-name
Create an interface-level class map, and enter class-map configuration
mode.
By default, no class maps are defined.
• (Optional) Use the match-all keyword to perform a logical-AND
of all matching statements under this class map. All match criteria
in the class map must be matched.
• (Optional) Use the match-any keyword to perform a logical-OR of
all matching statements under this class map. One or more match
criteria must be matched.
• For class-map-name, specify the name of the class map.
If neither the match-all or match-any keyword is specified, the default
is match-all.
Note Because only one match command per class map is supported,
the match-all and match-any keywords function the same.
Step 7
match input-interface interface-id-list Specify the physical ports on which the interface-level class map acts.
You can specify up to six ports as follows:
• A single port (counts as one entry)
• A list of ports separated by a space (each port counts as an entry)
• A range of ports separated by a hyphen (counts as two entries)
This command can only be used in the child-level policy map and must
be the only match condition in the child-level policy map.
Step 8
exit Return to class-map configuration mode.
Step 9
exit Return to global configuration mode.
Step 10
policy-map policy-map-name Create an interface-level policy map by entering the policy-map name,
and enter policy-map configuration mode.
By default, no policy maps are defined, and no policing is performed.
