Chapter 8 Configuring SNMP
Configuring SNMP Management Traffic Services
Creating and Configuring a Layer 3 and Layer 4 Class Map
To create a Layer 3 and Layer 4 class map to classify the SNMP management
traffic that can be received by the ACE, use the
class-map type management
command in configuration mode. This command allows the ACE to receive
network management traffic by identifying the incoming IP protocols that the
ACE can receive by using the client source host IP address and subnet mask as the
matching criteria. A class map of
type management
defines the allowed network
traffic as a form of management security for protocols such as SNMP.
A class map can have multiple
match
commands. You can configure class maps
to define multiple SNMP management protocol and source IP address 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 as follows:
class-map type management
[
match-all
|
match-any
]
map_name
The keywords, arguments, and options are as follows:
•
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 the
same type).
–
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 different types).
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.
