DESCRIPTION
"The maximum number of concurrent active lookup requests
that are allowed within an agent implementation. A value
of 0 for this object implies that there is no limit for
the number of concurrent active requests in effect."

"The amount of time to wait before automatically

dependent lookupResultsTable entries
after the lookup operation represented by an
lookupCtlEntry has completed.
An lookupCtEntry is considered complete
when its lookupCtlOperStatus object has a

::= { lookupObjects 3 }
lookupCtlEntry OBJECT-TYPE
SYNTAX LookupCtlEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Defines an entry in the lookupCtlTable. A
lookupCtlEntry is initially indexed by
lookupCtlOwnerIndex, which is of type SnmpAdminString,
a textual convention that allows for use of the SNMPv3
View-Based Access Control Model (RFC 2575 [11], VACM)
and also allows an management application to identify
its entries. The second index element,
lookupCtlOperationName, enables the same
lookupCtlOwnerIndex entity to have multiple outstanding
requests.
The value of lookupCtlTargetAddressType determines which
lookup function to perform. Specification of dns(16)
as the value of this index implies that the gethostbyname
function should be performed to determine the numeric
addresses associated with a symbolic name via
lookupResultsTable entries. Use of a value of either
ipv4(1) or ipv6(2) implies that the gethostbyaddr function
should be performed to determine the symbolic name(s)
associated with a numeric address at a remote host."

lookupCtlOwnerIndex OBJECT-TYPE
SYNTAX SnmpAdminString (SIZE(0..32))
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"To facilitate the provisioning of access control by a
security administrator using the View-Based Access
Control Model (RFC 2575, VACM) for tables in which
multiple users may need to independently create or
modify entries, the initial index is used as an 'owner
index'. Such an initial index has a syntax of
SnmpAdminString, and can thus be trivially mapped to a
securityName or groupName as defined in VACM, in
accordance with a security policy.
When used in conjunction with such a security policy all
entries in the table belonging to a particular user (or
group) will have the same value for this initial index.
For a given user's entries in a particular table, the
object identifiers for the information in these entries
will have the same subidentifiers (except for the
'column' subidentifier) up to the end of the encoded
owner index. To configure VACM to permit access to this
portion of the table, one would create
vacmViewTreeFamilyTable entries with the value of
vacmViewTreeFamilySubtree including the owner index
portion, and vacmViewTreeFamilyMask 'wildcarding' the
column subidentifier. More elaborate configurations
are possible."

within the scope of an lookupCtlOwnerIndex."
::= { lookupCtlEntry 2 }
lookupCtlTargetAddressType OBJECT-TYPE
SYNTAX InetAddressType
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"Specifies the type of address for either performing a
gethostbyname or a gethostbyaddr function at a remote host.
Specification of dns(16) as the value for this object
means that the gethostbyname function should be performed
to return one or more numeric addresses. Use of a value
of either ipv4(1) or ipv6(2) means that the gethostbyaddr
function should be used to return the symbolic names
associated with a remote host."
::= { lookupCtlEntry 3 }
lookupCtlTargetAddress OBJECT-TYPE
SYNTAX InetAddress
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"Specifies the address used for a resolver lookup at a
remote host. The corresponding lookupCtlAddressType
objects determines its type as well as the function
that can be requested.
A value for this object MUST be set prior to
transitioning its corresponding lookupCtlEntry to
active(1) via lookupCtlRowStatus."
::= { lookupCtlEntry 4 }
lookupCtlOperStatus OBJECT-TYPE
SYNTAX INTEGER {
notStarted(2), -- operation has not started
completed(3) -- operation is done
}
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Reflects the operational state of an lookupCtlEntry:
enabled(1) - Operation is active.
notStarted(2) - Operation has not been enabled.
completed(3) - Operation has completed.
An operation is automatically enabled(1) when its
lookupCtlRowStatus object is transitioned to active(1)
status. Until this occurs lookupCtlOperStatus MUST
report a value of notStarted(2). After the lookup
operation completes (success or failure) the value
for lookupCtlOperStatus MUST be transitioned to
completed(3)."
::= { lookupCtlEntry 5 }
lookupCtlTime OBJECT-TYPE
SYNTAX Unsigned32
UNITS "milliseconds"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Reports the number of milliseconds that a lookup
operation required to be completed at a remote host.
Completed means operation failure as well as
success."
::= { lookupCtlEntry 6 }
lookupCtlRc OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The system specific return code from a lookup
operation. All implementations MUST return a value
of 0 for this object when the remote lookup
operation succeeds. A non-zero value for this
objects indicates failure. It is recommended that
implementations that support errno use it as the
value of this object to aid a management
application in determining the cause of failure."
::= { lookupCtlEntry 7 }
lookupCtlRowStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object allows entries to be created and deleted
in the lookupCtlTable.
A remote lookup operation is started when an
entry in this table is created via an SNMP SET
request and the entry is activated. This
occurs by setting the value of this object
to CreateAndGo(4) during row creation or
by setting this object to active(1) after
the row is created.
A value MUST be specified for lookupCtlTargetAddress
prior to a transition to active(1) state being
accepted.
A remote lookup operation starts when its entry
first becomes active(1). Transitions in and
out of active(1) state have no effect on the
operational behavior of a remote lookup
operation, with the exception that deletion of
an entry in this table by setting its RowStatus
object to destroy(6) will stop an active
remote lookup operation.
The operational state of a remote lookup operation
can be determined by examination of its
lookupCtlOperStatus object."

'Textual Conventions for SMIv2.'"

-- Lookup Results Table
lookupResultsTable OBJECT-TYPE
SYNTAX SEQUENCE OF LookupResultsEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Defines the Lookup Results Table for providing
the capability of determining the results of a
operation at a remote host.
One or more entries are added to the
lookupResultsTable when a lookup operation,
as reflected by an lookupCtlEntry, completes
successfully. All entries related to a
successful lookup operation MUST be added
to the lookupResultsTable at the same time
that the associating lookupCtlOperStatus
object is transitioned to completed(2).
The number of entries added depends on the
results determined for a particular lookup
operation. All entries associated with an
lookupCtlEntry are removed when the
lookupCtlEntry is deleted.
A remote host can be multi-homed and have more
than one IP address associated with it
(gethostbyname results) and/or it can have more
than one symbolic name (gethostbyaddr results).
The gethostbyaddr function is called with a
host address as its parameter and is used
primarily to determine a symbolic name to
associate with the host address. Entries in
the lookupResultsTable MUST be made for each
host name returned. The official host name MUST
be assigned a lookupResultsIndex of 1.
The gethostbyname function is called with a
symbolic host name and is used primarily to
retrieve a host address. If possible the
primary host address SHOULD be assigned a
lookupResultsIndex of 1."
