FlowLmtIntfClass ::= TEXTUAL-CONVENTION
    STATUS current
    DESCRIPTION
        "The classes of interfaces, or ports, available under the
         Flow Limiting feature.
         
         userPort
             A port with a single user (workstation, PC, etc.)
             attached to it.
 
         serverPort
             A port with a server attached to it.  This class may
             encompass a wide range of server types from a small
             workgroup print server to an enterprise exchange
             server.  Alternately, an administrator may choose to
             configure an interface with a small print server as
             a userPort since their flow setup needs may be
             similar to that of a user port.
 
         aggregatedUserPort
             A port likely to have multiple end stations attached
             either through a wireless access point or an
             unmanaged low cost hub or switch.   It is expected that
             this class may also be used instead of interSwitchLink
             when switches are interconnected using a lower
             speed link.
 
         interSwitchLink
             A port that is used as a high-speed interconnect
             between two intelligent switches or routers.
 
         Unspecified
             A port in which nothing can be assumed about its
             intended use.
         
         These classes are only guides.  The classes can be configured
         with any limits, and any interface can associated with any
         class."

FlowLmtIntfAction ::= TEXTUAL-CONVENTION
    STATUS current
    DESCRIPTION
        "The possible actions that the Flow Limiting feature can
         take when flow activity exceeds the associated action
         limits.

           generateNotification(0)
             - Generate the respective SNMP notification.

           dropExcessFlows(1)
             - Drop flow setup requests in excess of the configured
               limit and discard the associated packets.  The use of
               this option could cause the entity to repetitively
               process setup requests for the dropped flows.  The
               process of dropping flow setup requests and their
               associated packets could cause end stations attached
               to this interface to behave in an indeterminate manner.
               The use of this option may also prevent the entity from
               being able to count additional flows and from reaching
               any additional configured limit.

           createDiscardFlows(2)
             - Create discard flows and discard the associated packets.
               The use of this option could cause end stations attached
               to this interface to behave in an indeterminate manner.

           disableInterface(3)
             - Operationally disable the interface, ifOperStatus for
               the interface MUST go into the 'down' state, and MUST
               remain in that state until the associated
               etsysFlowLimitingIntfStatus is set to operational, the
               Flow Limiting feature is disabled, or the entity is
               reset.

         The 'generateNotification(0)' will always be performed if
         it is a selected action, is globally enabled, and does not
         exceed the global rate limit for such notifications.  It
         MUST be generated in such a way that the information in the
         notification indicates the condition on the interface after
         any other indicated action has been taken.  If one or more
         other actions are selected only the one with the highest
         precedence will be taken.  The order of precedence, from
         highest to lowest, of the actions are 'disableInterface',
         'createDiscardFlows', and finally 'dropExcessFlows'.  If
         etsysFlowLimitingSystemInterfaceShutdown is disabled the
         selected action with the next highest precedence will be
         taken."

         disabled (2) - Flow Limiting will not generate SNMP
                        Notifications under any conditions.

         A notification is generated when a value is first detected
         above its respective configured limit.  That notification
         MUST NOT be generated again until the respective value has
         transitioned through its respective limit in both directions.
