This is the MIB module for the SNMP Agent Extensibility
Protocol (AgentX).  This MIB module will be implemented by
the master agent.

The default length of time, in seconds, that the master
agent should allow to elapse after dispatching a message
to a session before it regards the subagent as not
responding.  This is a system-wide value that may
override the timeout value associated with a particular
session (agentxSessionTimeout) or a particular registered
MIB region (agentxRegTimeout).  If the associated value of
agentxSessionTimeout and agentxRegTimeout are zero, or
impractical in accordance with implementation-specific
procedure of the master agent, the value represented by
this object will be the effective timeout value for the

master agent to await a response to a dispatch from a
given subagent.

The AgentX protocol version supported by this master agent.
The current protocol version is 1.  Note that the master agent
must also allow interaction with earlier version subagents.

The value of sysUpTime when the last row creation or deletion
occurred in the agentxConnectionTable.

The agentxConnectionTable tracks all current AgentX transport
connections.  There may be zero, one, or more AgentX sessions
carried on a given AgentX connection.

An agentxConnectionEntry contains information describing a
single AgentX transport connection.  A connection may be

used to support zero or more AgentX sessions.  An entry is
created when a new transport connection is established,
and is destroyed when the transport connection is terminated.

agentxConnIndex contains the value that uniquely identifies
an open transport connection used by this master agent
to provide AgentX service.  Values of this index should
not be re-used.  The value assigned to a given transport
connection is constant for the lifetime of that connection.

The value of sysUpTime when this connection was established
and, therefore, its value when this entry was added to the table.

The transport protocol in use for this connection to the
subagent.

The transport address of the remote (subagent) end of this
connection to the master agent.  This object may be zero-length
for unix-domain sockets (and possibly other types of transport
addresses) since the subagent need not bind a filename to its
local socket.

The value of sysUpTime when the last row creation or deletion
occurred in the agentxSessionTable.

A table of AgentX subagent sessions currently in effect.

Information about a single open session between the AgentX
master agent and a subagent is contained in this entry.  An
entry is created when a new session is successfully established
and is destroyed either when the subagent transport connection
has terminated or when the subagent session is closed.

A unique index for the subagent session.  It is the same as
h.sessionID defined in the agentx header.  Note that if
a subagent's session with the master agent is closed for
any reason its index should not be re-used.
A value of zero(0) is specifically allowed in order
to be compatible with the definition of h.sessionId.

This is taken from the o.id field of the agentx-Open-PDU.
This attribute will report a value of '0.0' for subagents
not supporting the notion of an AgentX session object
identifier.

A textual description of the session.  This is analogous to
sysDescr defined in the SNMPv2-MIB in RFC 1907 [19] and is
taken from the o.descr field of the agentx-Open-PDU.
This attribute will report a zero-length string value for
subagents not supporting the notion of a session description.

Possible values are:


up, down
                

The administrative (desired) status of the session.  Setting
the value to 'down(2)' closes the subagent session (with c.reason
set to 'reasonByManager').

The value of sysUpTime when this session was opened and,
therefore, its value when this entry was added to the table.

The version of the AgentX protocol supported by the
session.  This must be less than or equal to the value of
agentxMasterAgentXVer.

The length of time, in seconds, that a master agent should
allow to elapse after dispatching a message to this session
before it regards the subagent as not responding.  This value
is taken from the o.timeout field of the agentx-Open-PDU.
This is a session-specific value that may be overridden by
values associated with the specific registered MIB regions
(see agentxRegTimeout). A value of zero(0) indicates that
the master agent's default timeout value should be used

(see agentxDefaultTimeout).

The value of sysUpTime when the last row creation or deletion
occurred in the agentxRegistrationTable.

Contains information for a single registered region.  An
entry is created when a session  successfully registers a
region and is destroyed for any of three reasons: this region
is unregistered by the session, the session is closed,
or the subagent connection is closed.

agentxRegIndex uniquely identifies a registration entry.
This value is constant for the lifetime of an entry.

The context in which the session supports the objects in this
region.  A zero-length context indicates the default context.

The starting OBJECT IDENTIFIER of this registration entry.  The
session identified by agentxSessionIndex implements objects
starting at this value (inclusive).  Note that this value could
identify an object type, an object instance, or a partial object
instance.

agentxRegRangeSubId is used to specify the range.  This is
taken from r.region_subid in the registration PDU.  If the value
of this object is zero, no range is specified.  If it is non-zero,
it identifies the `nth' sub-identifier in r.region for which
this entry's agentxRegUpperBound value is substituted in the
OID for purposes of defining the region's upper bound.

agentxRegUpperBound represents the upper-bound sub-identifier in
a registration.  This is taken from the r.upper_bound in the
registration PDU.  If agentxRegRangeSubid (r.region_subid) is
zero, this value is also zero and is not used to define an upper
bound for this registration.

The registration priority.  Lower values have higher priority.
This value is taken from r.priority in the register PDU.
Sessions should use the value of 127 for r.priority if a
default value is desired.

The timeout value, in seconds, for responses to
requests associated with this registered MIB region.
A value of zero(0) indicates the default value (indicated
by by agentxSessionTimeout or agentxDefaultTimeout) is to
be used.  This value is taken from the r.timeout field of
the agentx-Register-PDU.

The value of agentxRegInstance is `true' for
registrations for which the INSTANCE_REGISTRATION
was set, and is `false' for all other registrations.

Values are:


agentxDefaultTimeout, 
agentxMasterAgentXVer, 
agentxConnTableLastChange, 
agentxConnOpenTime, 
agentxConnTransportDomain, 
agentxConnTransportAddress, 
agentxSessionTableLastChange, 
agentxSessionTimeout, 
agentxSessionObjectID, 
agentxSessionDescr, 
agentxSessionAdminStatus, 
agentxSessionOpenTime, 
agentxSessionAgentXVer, 
agentxRegistrationTableLastChange, 
agentxRegContext, agentxRegStart, 
agentxRegRangeSubId, 
agentxRegUpperBound, agentxRegPriority, 
agentxRegTimeout, agentxRegInstance

All accessible objects in the AgentX MIB.

The compliance statement for SNMP entities that implement the
AgentX protocol.  Note that a compliant agent can implement all
objects in this MIB module as read-only.
