This MIB contains the basic objects for managing a
        Cisco Appliance Services Architecture (CASA) Entity. A
        CASA Entity can be a Manager or a Forwarding Agent as
        defined below. The basic objects included in this mib
        are those to configure CASA, retrieve CASA's state and
        information about the fixed affinity cache.
        The following gives a list of definitions and a
        description of how Service Managers and Forwarding
        Agents interact. For a more detailed description, see
        the Cisco Appliance Services Architecture (CASA)
        CASA is a protocol allowing software entities (called
        Appliances, examples are web caches, firewalls, load
        balancers) to control the behavior of network hardware
        devices (called Forwarding Agents, examples are
        switches or routers) by providing a set of rules used
        to handle network traffic.
        A Network Appliance (referred to as an Appliance) is
        any subsystem whose purpose is to provide a specific
        additional value-added service to the network device,
        and could be implemented as a standalone box, a line
        card or processor card, or a software subsystem.
        Examples of Network Appliances would include Load
        Balancers, WebCaches, and Firewalls.
        An Appliance tells Fowarding Agents how to handle
        packets based on their source and destination IP
        addresses and ports, and IP protocol fields.  This set
        of information is called an Affinity.
        A Service Manager is an Appliance that requests
        packet flows from Forwarding Agents through CASA.
        A Real Server is a physical computing engine or part
        of that physical computing engine that offers one or
        more application services to a set of clients in the
        A packet flow is a TCP connection or a sequence of UDP
        packets between a client and a specific Real Server,
        pertaining to a specific application. Flows are
        represented by entries in the affinity cache tables.
        The Service Manager requests packet flows from
        Forwarding Agents by sending Affinities which contains
        wildcards on some of the Affinity fields. Affinities
        that contain wildcards in some of the fields are
        called Wildcard Affinities.  The Service Manager may
        send the Forwarding Agent an Affinity containing
        explicit values for each of the fields.  These
        Affinities are called Fixed Affinities.
        Typically Wildcard Affinities are used to instruct the
        Forwarding Agent to send packets received by the
        Forwarding Agent, which match the Wildcard Affinity,
        to the Service Manager. When the Service Manager
        receives the matching packet, the Service Manager
        typically will send the Forwarding Agent a Fixed
        Affinity. The Forwarding Agent uses Fixed Affinities
        to match packets coming from the network, execute any
        processing required on that packet, and forward that
        packet to a destination IP address (designated in the
        Fixed Affinity) called the Dispatch Address.
        When an IP packet arrives at the Forwarding Agent, the
        Forwarding Agent attempts to match the packet with the
        Fixed Affinities in the Fixed Affinity cache.  If
        there is no match, an attempt is made to match the
        packet with the list of Wildcard Affinities. If there
        is no match the packet is routed normally. If there is
        a match with a Wildcard Affinity, the Forwarding Agent
        sends the packet to the Service Manager who will send
        the Forwarding Manager a Fixed Affinity which provides
        information on how to process IP packets similar to
        the one received by the Forwarding Agent. Processing
        of such packets may include sending the packet to the
        Service Manager. Such packets are called Interest
        Packets.  Alternatively a Tickle Packet may be sent to
        the Service Manager which is an indication that a
        matched packet has been received by the Forwarding
