Number of bytes of data for all the packets
which matched any Wildcard Affinity.

Number of bytes of data for all the packets which
matched any Wildcard Affinity. This object is a 64-bit
version of ccfaWildcardAffTotalBytes.

Number of packets that matched any Wildcard Affinity.

This is the number of Wildcard Affinities for which
this Forwarding Agent is actively using for handling
TCP and UDP packets. This is the number of entries in
ccfaWildcardAffTable.

true indicates that
ciscoCasaFaWildcardAffCreated and
ciscoCasaFaWildcardAffDeleted
notification generation is enabled.
false indicates that
ciscoCasaFaWildcardAffCreated and
ciscoCasaFaWildcardAffDeleted
notification generation is disabled.

This is the maximum number of Wildcard Affinities
(high water mark) concurrently held in the Wildcard
Affinity cache since last time cCasaState transitioned
to cCasaEnabled or since this object was reset.
Resetting this object is achieved by setting this
object to 0. Attempting to set this object to any
other value will result in a wrongValue error.

This indicates when ccfaWildcardAffHiWtrMark
was set to 0.

This is the number of Wildcard Affinities for which
this Forwarding Agent was not able to accept
(i.e. denied) because a mandatory action item included
with the Wildcard Affinity was not supported by this
Forwarding Agent.

This is the number of Wildcard Affinities for which
this Forwarding Agent did not process (i.e. dropped).
This can happen because of low resource conditions
prevailing in the Forwarding Agent, such as low
memory.

A list of Wildcard Affinity entities.
Entries are added to this table dynamically by the
subagent when Wildcard Affinities are received on the
multicast IP address (see cCasaMulticastAddress in the
CISCO-CASA-MIB) for which this Forwarding Agent is
listening.

A list of traffic statistics.
Entries are added to this table dynamically by the
subagent when Fixed Affinities are received from the
Appliance indicating a dispatch IP address which is
not currently in the table. When there are no Fixed
Affinities left which contain ccfaDispatchAddress in
the Dispatch Address field, a timer is invoked. The
entry is deleted when this timer expires if no new
Fixed Affinities are received with the Dispatch
Address field equal to ccfaDispatchAddress.

A list of dispatch addresses for each advertised
address.
An entry is added to this table by the subagent when
the Wildcard Affinity associated with a received Fixed
Affinity has ccfaWildcardAffDispatch set to true
and the entry is not already in the table. An entry is
deleted from this table when all fixed affinities
containing the dispatch address for the associated
advertised address, time out.

The value of this index uniquely identifies
this Wildcard Affinity from others in the table.

The value used to compare the source IP address
of the TCP and UDP packets. When the comparison is
done, ccfaWildcardAffSourceMask is used as the
mask on this object.

The value used to compare the destination IP address
of the TCP and UDP packets. When the comparison is
done, ccfaWildcardAffDestinationMask is used as
the mask on this object.

The value used to compare the source port of the TCP
and UDP packets. A value of 0 means all port numbers
will match.

The value used to compare the destination port of the
TCP and UDP packets.  A value of 0 means all port
numbers will match.

The value used to compare the IP Protocol field of
the TCP and UDP packets.  A value of 0 means all
protocol numbers will match.

True indicates that fragments are to be sent to the
Service Manager,
false indicates that fragments are compared against
fields in this Wildcard Affinity for a possible
match in which case the fragment is sent to the
Service Manager.

The IP mask indicating which bits in the
ccfaWildcardAffSourceAddr are relevant. For each
set bit in this mask, the corresponding bits in
ccfaWildcardAffSourceAddr and the source IP
address of the received packet must be equal in order
to match this Wildcard Affinity.

The IP mask indicating which bits in the
ccfaWildcardAffDestinationAddr are relevant. For each
set bit in this mask, the corresponding bits in
ccfaWildcardAffDestinationAddr and the destination IP
address of the received packet must be equal in order
to match this Wildcard Affinity.

Affinity or any Fixed Affinity associated with this
Wildcard Affinity, that were forwarded to the
destination IP address.

Number of packets which matched this Wildcard
Affinity or any Fixed Affinity associated with this
Wildcard Affinity, that were forwarded to the
destination IP address. This object is a 64-bit
version of ccfaWildcardAffPackets.

From a logical point of view, this is the number of
TCP/UDP flows resulting from packets received which
matched this Wildcard Affinity.
A flow is a sequence of IP packets from a specific
client to a specific real server going through this
Forwarding Agent.
Literally this is the current number of Fixed Affinity
entries in the Fixed Affinity cache, that were put
there as a result of packets matching this Wildcard
Affinity.

Date and time when this Wildcard Affinity was
inserted into this table.

Number of expected Fixed Affinities that were not
received from the Service Manager within a period of
time from when a Fixed Affinity was requested by this
Forwarding Agent.

true indicates that the IP address defined by
ccfaWildcardAffDestinationAddr is to be
advertised by the routing protocol in this
Forwarding Agent.
false indicates that the IP address is not to be
advertised.

The IP address of the CASA entity to which Interest
Packets should be forwarded by this Forwarding Agent.

The UDP port of the CASA entity to which Interest
Packets should be forwarded by this Forwarding Agent.

The criteria used to identify an Interest Packet.
When such a packet is identified, that packet is sent
to the entity described by
ccfaWildcardAffInterestAddr and
ccfaWildcardAffInterestPort.

The criteria used to identify an Interest Packet
resulting in a Tickle Packet being sent to the entity
described by ccfaWildcardAffInterestAddr and
ccfaWildcardAffInterestPort.

true indicates that the MAC address of the IP packet
should be modified to that of the dispatch
entity who's IP address is given by
ccfaWildcardAffDispatchAddr, prior to

This MIB module in conjunction with the
CISCO-CASA-MIB, defines the SNMP management
information base for managing the Cisco Appliance
Services Architecture (CASA) Forwarding Agent.
The following is a set of definitions used in the
rest of the MIB.
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
network.
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
Agent.
