The Lookup MIB (DISMAN-NSLOOKUP-MIB) enables determination of either the name(s) corresponding to a host address or of the address(es) associated with a host name at a remote host. read-write current 1.3.6.1.2.1.82.1.1 "requests" 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. read-write current 1.3.6.1.2.1.82.1.2 "seconds" The amount of time to wait before automatically deleting an entry in the lookupCtlTable and any dependent lookupResultsTable entries after the lookup operation represented by an lookupCtlEntry has completed. An lookupCtEntry is considered complete when its lookupCtlOperStatus object has a value of completed(3). read-write current 1.3.6.1.2.1.82.1.1 "requests" 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. read-write current 1.3.6.1.2.1.82.1.2 "seconds" The amount of time to wait before automatically deleting an entry in the lookupCtlTable and any dependent lookupResultsTable entries after the lookup operation represented by an lookupCtlEntry has completed. An lookupCtEntry is considered complete when its lookupCtlOperStatus object has a value of completed(3). not-accessible current 1.3.6.1.2.1.82.1.3.1 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. not-accessible current 1.3.6.1.2.1.82.1.4.1 Defines an entry in the lookupResultsTable. The first two index elements identify the lookupCtlEntry that a lookupResultsEntry belongs to. The third index element selects a single lookup operation result. read-write current 1.3.6.1.2.1.82.1.3.1.3 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. 0 1 -- these named numbers are aligned 2 -- with AddressFamilyNumbers from 16 -- IANA-ADDRESS-FAMILY-NUMBERS-MIB read-write current 1.3.6.1.2.1.82.1.3.1.4 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. read-only current 1.3.6.1.2.1.82.1.3.1.5 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). 2 -- operation has not started 3 -- operation is done read-only current 1.3.6.1.2.1.82.1.3.1.6 "milliseconds" 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. read-only current 1.3.6.1.2.1.82.1.3.1.7 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. read-write current 1.3.6.1.2.1.82.1.3.1.8 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. 1 2 -- the following value is a state: -- this value may be read, but not written 3 -- the following three values are -- actions: these values may be written, -- but are never read 4 5 6 read-only current 1.3.6.1.2.1.82.1.4.1.2 Indicates the type of result of a remote lookup operation. A value of unknown(0) implies that either the operation hasn't been started or that it has failed. 0 1 -- these named numbers are aligned 2 -- with AddressFamilyNumbers from 16 -- IANA-ADDRESS-FAMILY-NUMBERS-MIB read-only current 1.3.6.1.2.1.82.1.4.1.3 Reflects a result for a remote lookup operation as per the value of lookupResultsAddressType.
