IANAifType ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "This data type is used as the syntax of the ifType object in the (updated) definition of MIB-II's ifTable.
The definition of this textual convention with the addition of newly assigned values is published periodically by the IANA, in either the Assigned Numbers RFC, or some derivative of it specific to Internet Network Management number assignments. (The latest arrangements can be obtained by contacting the IANA.)
Requests for new values should be made to IANA via email ([email protected]).
The relationship between the assignment of ifType values and of OIDs to particular media-specific MIBs is solely the purview of IANA and is subject to change without notice. Quite often, a media-specific MIB's OID-subtree assignment within MIB-II's 'transmission' subtree will be the same as its ifType value. However, in some circumstances this will not be the case, and implementors must not pre-assume any specific relationship between ifType values and transmission subtree OIDs."

-- -- The Interface Test Table -- -- This group of objects is optional. However, a media-specific -- MIB may make implementation of this group mandatory. -- -- This table replaces the ifExtnsTestTable --
ifTestTable OBJECT-TYPE SYNTAX SEQUENCE OF IfTestEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "This table contains one entry per interface. It defines objects which allow a network manager to instruct an agent to test an interface for various faults. Tests for an interface are defined in the media-specific MIB for that interface. After invoking a test, the object ifTestResult can be read to determine the outcome. If an agent can not perform the test, ifTestResult is set to so indicate. The object ifTestCode can be used to provide further test-specific or interface-specific (or even enterprise-specific) information concerning the outcome of the test. Only one test can be in progress on each interface at any one time. If one test is in progress when another test is invoked, the second test is rejected. Some agents may reject a test when a prior test is active on another interface. Before starting a test, a manager-station must first obtain 'ownership' of the entry in the ifTestTable for the interface to be tested. This is accomplished with the ifTestId and ifTestStatus objects as follows:
try_again: get (ifTestId, ifTestStatus) while (ifTestStatus != notInUse) /* * Loop while a test is running or some other * manager is configuring a test. */ short delay get (ifTestId, ifTestStatus) }
/* * Is not being used right now -- let's compete * to see who gets it. */ lock_value = ifTestId
if ( set(ifTestId = lock_value, ifTestStatus = inUse, ifTestOwner = 'my-IP-address') == FAILURE) /* * Another manager got the ifTestEntry -- go * try again */ goto try_again;
/* * I have the lock */ set up any test parameters.
/* * This starts the test */ set(ifTestType = test_to_run);
wait for test completion by polling ifTestResult
when test completes, agent sets ifTestResult agent also sets ifTestStatus = 'notInUse'
retrieve any additional test results, and ifTestId
if (ifTestId == lock_value+1) results are valid
A manager station first retrieves the value of the appropriate ifTestId and ifTestStatus objects, periodically repeating the retrieval if necessary, until the value of ifTestStatus is 'notInUse'. The manager station then tries to set the same ifTestId object to the value it just retrieved, the same ifTestStatus object to 'inUse', and the corresponding ifTestOwner object to a value indicating itself. If the set operation succeeds then the manager has obtained ownership of the ifTestEntry, and the value of the ifTestId object is incremented by the agent (per the semantics of TestAndIncr). Failure of the set operation indicates that some other manager has obtained ownership of the ifTestEntry.
Once ownership is obtained, any test parameters can be setup, and then the test is initiated by setting ifTestType. On completion of the test, the agent sets ifTestStatus to 'notInUse'. Once this occurs, the manager can retrieve the results. In the (rare) event that the invocation of tests by two network managers were to overlap, then there would be a possibility that the first test's results might be overwritten by the second test's results prior to the first results being read. This unlikely circumstance can be detected by a network manager retrieving ifTestId at the same time as retrieving the test results, and ensuring that the results are for the desired request.
If ifTestType is not set within an abnormally long period of time after ownership is obtained, the agent should time-out the manager, and reset the value of the ifTestStatus object back to 'notInUse'. It is suggested that this time-out period be 5 minutes.
In general, a management station must not retransmit a request to invoke a test for which it does not receive a response; instead, it properly inspects an agent's MIB to determine if the invocation was successful. Only if the invocation was unsuccessful, is the invocation request retransmitted.
Some tests may require the interface to be taken off- line in order to execute them, or may even require the agent to reboot after completion of the test. In these circumstances, communication with the management station invoking the test may be lost until after completion of the test. An agent is not required to support such tests. However, if such tests are supported, then the agent should make every effort to transmit a response to the request which invoked the test prior to losing communication. When the agent is restored to normal service, the results of the test are properly made available in the appropriate objects. Note that this requires that the ifIndex value assigned to an interface must be unchanged even if the test causes a reboot. An agent must reject any test for which it cannot, perhaps due to resource constraints, make available at least the minimum amount of information after that test completes." ::= { ifMIBObjects 3 }

ifTestCode OBJECT-TYPE SYNTAX OBJECT IDENTIFIER MAX-ACCESS read-only STATUS current DESCRIPTION "This object contains a code which contains more specific information on the test result, for example an error-code after a failed test. Error codes and other values this object may take are specific to the type of interface and/or test. The value may have the semantics of either the AutonomousType or InstancePointer textual conventions as defined in RFC 1443. The identifier:
testCodeUnknown OBJECT IDENTIFIER ::= { 0 0 }
is defined for use if no additional result code is available." ::= { ifTestEntry 5 }

-- Generic Receive Address Table -- -- This group of objects is mandatory for all types of -- interfaces which can receive packets/frames addressed to -- more than one address. -- -- This table replaces the ifExtnsRcvAddr table. The main -- difference is that this table makes use of the RowStatus -- textual convention, while ifExtnsRcvAddr did not.
ifRcvAddressTable OBJECT-TYPE SYNTAX SEQUENCE OF IfRcvAddressEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "This table contains an entry for each address (broadcast, multicast, or uni-cast) for which the system will receive packets/frames on a particular interface, except as follows:
- for an interface operating in promiscuous mode, entries are only required for those addresses for which the system would receive frames were it not operating in promiscuous mode.
- for 802.5 functional addresses, only one entry is required, for the address which has the functional address bit ANDed with the bit mask of all functional addresses for which the interface will accept frames." ::= { ifMIBObjects 4 }

::= { ifRcvAddressEntry 2 }
ifRcvAddressType OBJECT-TYPE SYNTAX INTEGER { other(1), volatile(2), nonVolatile(3) }
MAX-ACCESS read-create STATUS current DESCRIPTION "This object has the value nonVolatile(3) for those entries in the table which are valid and will not be deleted by the next restart of the managed system. Entries having the value volatile(2) are valid and exist, but have not been saved, so that will not exist after the next restart of the managed system. Entries having the value other(1) are valid and exist but are not classified as to whether they will continue to exist after the next restart."

GROUP ifTestGroup DESCRIPTION "This group is optional. Media-specific MIBs which require interface tests are strongly encouraged to use this group for invoking tests and reporting results. A medium specific MIB which has mandatory tests may make implementation of this group mandatory."
GROUP ifRcvAddressGroup DESCRIPTION "The applicability of this group MUST be defined by the media-specific MIBs. Media-specific MIBs must define the exact meaning, use, and semantics of the addresses in this group."
