Classification Rules

Classification rules associate specific traffic classifications or policy behaviors with the policy role. There are two aspects of classification rule configuration:
  • The association of a traffic classification with a policy role by assigning the traffic classification to an administrative profile.
  • The assignment of policy rules that define desired policy behaviors for the specified traffic classification type.

Both the administrative profile and policy rules are associated with the policy role by specifying the admin-pid option, in the case of an administrative profile, or a profile-index value, in the case of the policy rule. Administrative profiles and policy rules are configured using the configure policy rule command.

The administrative profile assigns a traffic classification to a policy role by using the admin-profile option of the configure policy rule command.

Note

Note

Standard policy supports the VLAN tag traffic classification for administrative profiles. All other traffic classifications are enhanced policy in an administrative profile context.

Policy rules are based on traffic classifications. Administrative Policy and Policy Rule Traffic Classifications provides the supported policy rule traffic classification command options and definitions. All other traffic classifications are supported by standard policy.

A detailed discussion of supported traffic classifications is available in the “Traffic Classification Rules” section of the Extreme Management Center Policy Manager online help.

A data value is associated with most traffic classifications to identify the specific network element for that classification. For data value and associated mask details, see the “Valid Values for Policy Classification Rules” table in the configure policy rule command discussion of the command reference guide for your platform.
