Chapter 4 Configuring Class Maps and Policy Maps
Configuring Layer 3 and Layer 4 Class Maps
Creating a Layer 3 and Layer 4 Network Traffic Class Map
To create a Layer 3 and Layer 4 class map to classify network traffic passing
through the ACE, use the
class-map
command in configuration mode.
A single class map can have multiple
match
commands that you can use to
specify the matching criteria. For example, you can configure class maps to define
multiple access group, source IP address, destination IP address, or port
commands in a group that you then associate with a traffic policy. The
match-all
and
match-any
keywords determine how the ACE evaluates multiple match
statements operations when multiple match criteria exist in a class map.
The syntax of this command is:
class-map
[
match-all
|
match-any
]
map_name
The arguments and options are:
•
match-all | match-any
—(Optional) Determines how the ACE evaluates
Layer 3 and Layer 4 network traffic when multiple match criteria exist in a
class map. The class map is considered a match if the
match
commands meet
one of the following conditions:
–
match-all
—All of the match criteria listed in the class map match the
network traffic class in the class map (typically
match
commands of
different types).
–
match-any
—Only one of the match criteria listed in the class map
matches the network traffic class in the class map (typically
match
commands of the same type).
The default setting is to meet all of the match criteria (
match-all
) in a class
map.
•
map_name
—Name assigned to the class map. Enter an unquoted text string
with no spaces and a maximum of 64 alphanumeric characters.
