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|ipv6classname]Defines the name of a traffic class and specifies whether a policy is to be applied to IPv4 or IPv6 packets, where
classnameis a text string (64 characters maximum.)After you enter the
classcommand, you enter the class configuration context to specify match criteria. A traffic class contains a series ofmatchandignorecommands, which specify the criteria used to classify packets.To configure a default traffic class, use the
default-classcommand 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

matchandignorecommands to configure a traffic class, the Advanced Traffic Management Guide.
Context: Global configuration
Syntax
[ no ]
policy mirrorpolicy-nameDefines 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
matchstatement in a class. No policy action is performed on packets that match anignorestatement.
Context: Policy configuration
Syntax
Defines the mirroring action to be applied on a pre-configured IPv4 or IPv6 traffic class when a packet matches the
matchcriteria in the traffic class. You can enter multipleclass action mirrorstatements in a policy.
[seq-number]The (optional)
seq-numberparameter sequentially orders the mirroring actions that you enter in a policy configuration. Actions are executed on matching packets in numerical order.Default: Mirroring action statements are numbered in increments of 10, starting at 10.
class[ipv4|ipv6classname]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 mirrorsessionConfigures mirroring for the destination and session specified by the
sessionparameter.
Context: Policy configuration
Syntax
[ no ]
default-class action mirror[sessionaction mirrorsession...]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.
Applying a mirroring policy on a port or VLAN interface
Enter one of the following service-policy commands
from the global configuration context.
Context: Global configuration
Syntax
interface<PORT-LIST>service-policypolicy-nameinConfigures the specified ports with a mirroring policy that is applied to inbound traffic on each interface.
Separate individual port numbers in a series with a comma, for example,
a1,b4,d3. Enter a range of ports by using a dash, for example,a1-a5.The mirroring policy name you enter must be the same as the policy name you configured with the
policy mirrorcommand.
Syntax
vlanvlan-idservice-policypolicy-nameinConfigures a mirroring policy on the specified VLAN that is applied to inbound traffic on the VLAN interface.
Valid VLAN ID numbers range from 1 to 4094.
The mirroring policy name you enter must be the same as the policy name you configured with the
policy mirrorcommand in the syntax ???.
