What Is ITF-MIB?
ITF-MIB is Alcatel's customized re-issue of the standard IETF Interfaces MIB (IF-MIB/RFC1573) tailored for its iSAM/ASAM broadband access-node platforms, adding per-object 'ALCATEL NOTE' annotations that specify hardware support, in-service modification rules, ranges, and default values for each interface parameter. It exposes the classic ifTable/ifXTable pair covering every network interface on the device -- type, MTU, speed, physical address, administrative/operational status, and both 32-bit and 64-bit traffic counters -- alongside ifStackTable, which records how sub-layer interfaces (for example a DSL line stacked under an ATM or Ethernet layer) relate to one another. An ifTestTable lets a management station remotely trigger and retrieve results from a manager-locked interface self-test, and ifRcvAddressTable lists which unicast, broadcast, and multicast addresses each interface will accept. Because it is built on the vendor-neutral IANAifType registry, the module can describe any interface technology the access node exposes, from copper DSL ports to Ethernet uplinks, while the Alcatel-specific notes flag which objects are actually implemented or writable on a given card. This makes ITF-MIB SNMP monitoring a foundational part of tracking both the software configuration and real-time traffic/error status of every physical and logical interface on an Alcatel access-node deployment.
IPNetwork Monitor allows you to monitor SNMP objects defined in ITF-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Nokia 7302 ISAM — current high-capacity DSL/GPON/fiber access node, 16-18 slots, 2x320 Gb/s switching
- Nokia 7330 ISAM FTTN (FD-8/FD-16) — current VDSL2 vectoring/bonding fiber-to-the-node access node
Monitoring Examples
An administrator would poll ifOperStatus against ifAdminStatus across the ifTable to spot interfaces that are administratively enabled but operationally down, such as a DSL port stuck down after a line fault, and cross-reference ifXTable's ifHCInOctets/ifHCOutOctets 64-bit counters to track high-volume broadband traffic without counter wraparound. Consulting ifStackTable would reveal which logical interface, such as a PPPoE or ATM layer, is stacked on top of a given physical DSL line, useful for tracing a fault up through the protocol stack. If a line card is suspected faulty, the operator could write to ifTestTable to invoke a self-test, then poll ifTestResult once ifTestStatus reports completion.
What Can Be Monitored
- interface administrative vs. operational status
- 32-bit and 64-bit interface traffic/error counters
- sub-layer interface stacking relationships
- remote interface self-test results
- per-interface accepted address list (unicast/broadcast/multicast)

OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| INT ifAdminStatus | 1.3.6.1.2.1.2.2.1.7 | INTEGER | read-write | The desired state of the interface. The testing(3) state indicates that no operational packets can be passed. When a managed system initializes, all interfaces start with ifAdminStatus in the down(2) state. As a result of either explicit management action or per configuration information retained by the managed system, ifAdminStatus is then changed to either the up(1) or testing(3) states (or remains in the down(2) state). ALCATEL NOTE: SUPPORT: YES INSRVMOD: YES RANGE: 'testing' not supported PERSIST: YES DEFVALUE: down UNITS: - |
| STR ifAlias | 1.3.6.1.2.1.31.1.1.1.18 | DisplayString | read-write | This object is an 'alias' name for the interface as specified by a network manager, and provides a non- volatile 'handle' for the interface. On the first instantiation of an interface, the value of ifAlias associated with that interface is the zero-length string. As and when a value is written into an instance of ifAlias through a network management set operation, then the agent must retain the supplied value in the ifAlias instance associated with the same interface for as long as that interface remains instantiated, including across all re- initializations/reboots of the network management system, including those which result in a change of the interface's ifIndex value. An example of the value which a network manager might store in this object for a WAN interface is the (Telco's) circuit number/identifier of the interface. Some agents may support write-access only for interfaces having particular values of ifType. An agent which supports write access to this object is required to keep the value in non-volatile storage, but it may limit the length of new values depending on how much storage is already occupied by the current values for other interfaces. |

This object has a value of true(1) when the station accepts all packets/frames transmitted on the media. The value true(1) is only legal on certain types of media. If legal, setting this object to a value of true(1) may require the interface to be reset before becoming effective.

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. |

Changing the value of this object from 'active' to 'notInService' or 'destroy' will likely have consequences up and down the interface stack. Thus, write access to this object is likely to be inappropriate for some types of interfaces, and many implementations will choose not to support write- access for any type of interface.

| ifTestTable | 1.3.6.1.2.1.31.1.3 | not-accessible | 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.

| OID ifTestType | 1.3.6.1.2.1.31.1.3.1.3 | AutonomousType | read-write | A control variable used to start and stop operator- initiated interface tests. Most OBJECT IDENTIFIER values assigned to tests are defined elsewhere, in association with specific types of interface. However, this document assigns a value for a full- duplex loopback test, and defines the special meanings of the subject identifier: noTest OBJECT IDENTIFIER ::= { 0 0 } When the value noTest is written to this object, no action is taken unless a test is in progress, in which case the test is aborted. Writing any other value to this object is only valid when no test is currently in progress, in which case the indicated test is initiated. When read, this object always returns the most recent value that ifTestType was set to. If it has not been set since the last initialization of the network management subsystem on the agent, a value of noTest is returned.
