match (class-map configuration)
If you enter the
class-map
{
match-all
|
match-any
}
class-map-name
global configuration command,
you can enter these
match
commands:
•
match access-group
acl-name
Note
The ACL must be an extended named ACL.
•
match input-interface
interface-id-list
•
match ip dscp
dscp-list
•
match ip precedence
ip-precedence-list
You cannot enter the
match access-group
acl-index
command.
To define packet classification on a physical-port basis, only one
match
command per class map is
supported. In this situation, the
match-all
and
match-any
keywords are equivalent.
For the
match
ip dscp
dscp-list
or the
match
ip precedence
ip-precedence-list
command, you can enter
a mnemonic name for a commonly used value. For example, you can enter the
match
ip dscp af11
command, which is the same as entering the
match
ip dscp 10
command. You can enter the
match
ip
precedence critical
command, which is the same as entering the
match
ip precedence 5
command. For
a list of supported mnemonics, enter the
match
ip dscp ?
or the
match
ip precedence ?
command to
see the command-line help strings.
Use the
input-interface
interface-id-list
keyword when you are configuring an interface-level class map
in a hierarchical policy map. For the
interface-id-list
, you can specify up to six entries.
Examples
This example shows how to create a class map called
class2
, which matches all the incoming traffic with
DSCP values of 10, 11, and 12:
Switch(config)#
class-map class2
Switch(config-cmap)#
match ip dscp 10 11 12
Switch(config-cmap)#
exit
This example shows how to create a class map called
class3
, which matches all the incoming traffic with
IP-precedence values of 5, 6, and 7:
Switch(config)#
class-map class3
Switch(config-cmap)#
match ip precedence 5 6 7
Switch(config-cmap)#
exit
This example shows how to delete the IP-precedence match criteria and to classify traffic using
acl1
:
Switch(config)#
class-map class2
Switch(config-cmap)#
match ip precedence 5 6 7
Switch(config-cmap)#
no match ip precedence
Switch(config-cmap)#
match access-group acl1
Switch(config-cmap)#
exit
This example shows how to specify a list of physical ports to which an interface-level class map in a
hierarchical policy map applies:
Switch(config)#
class-map match-all class4
Switch(config-cmap)#
match input-interface gigabitethernet0/1 gigabitethernet0/2
Switch(config-cmap)#
exit
