Rules in the first classifier are set up with an action to set class_id. Rules in the second classifier are setup to use the class_id as the key to match on the identity specific policies. The class_id is the common attribute between the two classifiers/tables, uniquely identifies the role of the identity.
This feature introduces one new ACL (Access Control List) action modifier for specifying the class-id from the first stage that will be input into the second stage. It also introduces one new ACL match criteria for matching the class-id within the second stage.
When a rule is installed in the first stage ACL table, it will be accounted for in the "Stage: LOOKUP" section of GUID-025DC865-11E3-445A-A30B-02375BCCD47C. When a rule is installed in the second stage ACL table, it is accounted for in the "Stage: INGRESS" section of this command. For example:
