This MIB module defines objects to help support coexistence
between SNMPv1, SNMPv2c, and SNMPv3.

The table of community strings configured in the SNMP
engine's Local Configuration Datastore (LCD).

The table of mask and mms values associated with the

snmpTargetAddrTable.

The snmpTargetAddrExtTable augments the
snmpTargetAddrTable with a transport address mask value
and a maximum message size value.  The transport address
mask allows entries in the snmpTargetAddrTable to define
a set of addresses instead of just a single address.
The maximum message size value allows the maximum
message size of another SNMP entity to be configured for
use in SNMPv1 (and SNMPv2c) transactions, where the
message format does not specify a maximum message size.

Information about a particular community string.

Information about a particular mask and mms value.

The unique index value of a row in this table.

The community string for which a row in this table
represents a configuration.

A human readable string representing the corresponding
value of snmpCommunityName in a Security Model
independent format.

The contextEngineID indicating the location of the
context in which management information is accessed
when using the community string specified by the
corresponding instance of snmpCommunityName.

The default value is the snmpEngineID of the entity in
which this object is instantiated.

The context in which management information is accessed
when using the community string specified by the corresponding
instance of snmpCommunityName.

This object specifies a set of transport endpoints
from which a command responder application will accept
management requests.  If a management request containing
this community is received on a transport endpoint other
than the transport endpoints identified by this object,
the request is deemed unauthentic.

The transports identified by this object are specified

in the snmpTargetAddrTable.  Entries in that table
whose snmpTargetAddrTagList contains this tag value
are identified.

If the value of this object has zero-length, transport
endpoints are not checked when authenticating messages
containing this community string.

The storage type for this conceptual row in the
snmpCommunityTable.  Conceptual rows having the value
'permanent' need not allow write-access to any
columnar object in the row.

The status of this conceptual row in the snmpCommunityTable.

An entry in this table is not qualified for activation
until instances of all corresponding columns have been
initialized, either through default values, or through
Set operations.  The snmpCommunityName and
snmpCommunitySecurityName objects must be explicitly set.

There is no restriction on setting columns in this table
when the value of snmpCommunityStatus is active(1).

The mask value associated with an entry in the
snmpTargetAddrTable.  The value of this object must
have the same length as the corresponding instance of
snmpTargetAddrTAddress, or must have length 0.  An
attempt to set it to any other value will result in
an inconsistentValue error.

The value of this object allows an entry in the
snmpTargetAddrTable to specify multiple addresses.
The mask value is used to select which bits of
a transport address must match bits of the corresponding
instance of snmpTargetAddrTAddress, in order for the
transport address to match a particular entry in the
snmpTargetAddrTable.  Bits which are 1 in the mask
value indicate bits in the transport address which
must match bits in the snmpTargetAddrTAddress value.

Bits which are 0 in the mask indicate bits in the
transport address which need not match.  If the
length of the mask is 0, the mask should be treated
as if all its bits were 1 and its length were equal
to the length of the corresponding value of
snmpTargetAddrTable.

This object may not be modified while the value of the
corresponding instance of snmpTargetAddrRowStatus is
active(1).  An attempt to set this object in this case
will result in an inconsistentValue error.

The maximum message size value associated with an entry
in the snmpTargetAddrTable.

The value of the agent-addr field of a Trap PDU which
is forwarded by a proxy forwarder application using
an SNMP version other than SNMPv1.  The value of this
object SHOULD contain the value of the agent-addr field
from the original Trap PDU as generated by an SNMPv1
agent.

The value of the community string field of an SNMPv1
message containing a Trap PDU which is forwarded by a
a proxy forwarder application using an SNMP version
other than SNMPv1.  The value of this object SHOULD
contain the value of the community string field from
the original SNMPv1 message containing a Trap PDU as
generated by an SNMPv1 agent.

A collection of objects providing for configuration
of community strings for SNMPv1 (and SNMPv2c) usage.

Objects which are used by proxy forwarding applications
when translating traps between SNMP versions.  These are
used to preserve SNMPv1-specific information when

translating to SNMPv2c or SNMPv3.
