Configuring classifier-based mirroring
For more information and a list of general steps for the process beginning with this command, see the information about restrictions on classifier-based mirroring.
Context: Global configuration
Syntax
[no] class [ipv4 | ipv6 classname]
Defines the name of a traffic class and specifies whether a policy is to be applied to IPv4 or IPv6 packets, where classname is a text string (64 characters maximum.)
After you enter the
class
command, you enter the class configuration context to specify match criteria. A traffic class contains a series of
match
and
ignore
commands, which specify the criteria used to classify packets.
To configure a default traffic class, use the
default-class
command as described below. A default class manages the packets that do not match the match/ignore criteria in any other classes in a policy.
Context: Class configuration
Syntax
[no] seq-number
[match | ignore ip-protocol source-address destination-address] [ip-dscp codepoint] [precedence precedence-value] [tos tos-value] [vlan vlan-id]

match
and
ignore
commands to configure a traffic class, the

Context: Global configuration
Syntax
[no] policy mirror policy-name
Defines the name of a mirroring policy and enters the policy configuration context.
A traffic policy consists of one or more classes and one or more mirroring actions configured for each class of traffic. The configured actions are executed on packets that match a
match
statement in a class. No policy action is performed on packets that match an
ignore
statement.
Context: Policy configuration
Syntax
[no] seq-number
class [ipv4 | ipv6 classname] action mirror session
Defines the mirroring action to be applied on a pre-configured IPv4 or IPv6 traffic class when a packet matches the
match
criteria in the traffic class. You can enter multiple
class action mirror
statements in a policy.
[seq-number]
|
The (optional)
|
|
Defines the preconfigured traffic class on which the mirroring actions in the policy are executed and specifies whether the mirroring policy is applied to IPv4 or IPv6 traffic in the class. The classname is a text string (64 characters maximum.) |
action mirror
session

Configures mirroring for the destination and session specified by the
|
Context: Policy configuration
Syntax
[no] default-class action mirror session [action mirror session ...]
Configures a default class that allows packets that are not matched nor ignored by any of the class configurations in a mirroring policy to be mirrored to the destination configured for the specified session.
