ADD CLASSIFIER INTERFACE

Syntax

ADD CLASSIFIER=classifiername INTERFACE={ type:id-range | id-range

| ifname-list | ALL } PRECEDENCE=1..255

Description Adds a CLASSIFIER to one or more Interfaces. As a result, the CLASSIFIER is applied to

every packet received on the Interface. This command attempts to add every specified

combination of CLASSIFIER and INTERFACE, and returns an error message for any com-

binations that cannot be added (e.g. due to conflicting PRECEDENCE, duplicate CLASSI-

FIERs, INTERFACEs that do not exist). Because classifiers are a limited resource, there

are constraints on the number of classifiers, and combinations of classifiers, that can be

supported on a given interface. If these limits are exceeded, then an alarm is raised on

the interface and operational classifier behavior may differ from the classifier configura-

tion. The “SHOW CLASSIFIER INTERFACE” command shows details about errors load-

ing the classifier configuration to a given port.

Options The following table gives the range of values for each option that can be specified with

this command and a default value (if applicable).

Example ADD CLASSIFIER=ipdrop INTERFACE=3.0 PRECEDENCE=69

Option Description Default Value

CLASSIFIER The name of the classifier.

INTERFACE The interface where the classifier is being added.

PRECE-

DENCE

Indicates whether actions from this CLASSIFIER are

performed when other matching CLASSIFIERS have

actions that conflict with the actions on this CLASSI-

FIER. In this case, actions from the CLASSIFIER with the

higher PRECEDENCE (smaller numeric value) are per-

formed, along with any actions from other matching

CLASSIFIERs that do not conflict with those actions.

Some PRECEDENCE values are reserved for internal

use (e.g. for IGMP snooping).

CLASSIFIERS for Filtering should use PRECEDENCE

values between 51 and 69.

CLASSIFIERS for setting fields in the packets should use

PRECEDENCE values between 146 and 199.
