DESCRIPTION
"The MIB module to describe generic objects for
network interface sub-layers. This MIB is an updated
version of MIB-II's ifTable, and incorporates the
extensions defined in RFC 1229."

DESCRIPTION
"This data type is used to model an administratively
assigned name of the owner of a resource. This
information is taken from the NVT ASCII character set.
It is suggested that this name contain one or more of
the following: ASCII form of the manager station's
transport address, management station name (e.g.,
domain name), network management personnel's name,
location, or phone number. In some cases the agent
itself will be the owner of an entry. In these cases,
this string shall be set to a string starting with
'agent'."

DESCRIPTION
"A unique value, greater than zero, for each interface

DESCRIPTION
"This textual convention is an extension of the

greater than zero value used to identify an interface
or interface sub-layer in the managed system. This
extension permits the additional value of zero. the
value zero is object-specific and must therefore be
defined as part of the description of any object which
uses this syntax. Examples of the usage of zero might
include situations where interface was unknown, or
when none or all interfaces need to be referenced."

"This object is an 'alias' name for the interface as

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,

how much storage is already occupied by the current

value x runs over the sub-layer with ifIndex value y,
then this table contains:
ifStackStatus.x.y=active
For each ifIndex value, I, which identifies an active
interface, there are always at least two instantiated
rows in this table associated with I. For one of
these rows, I is the value of ifStackHigherLayer; for
the other, I is the value of ifStackLowerLayer. (If I
is not involved in multiplexing, then these are the
only two rows associated with I.)
For example, two rows exist even for an interface
which has no others stacked on top or below it:

ifTestTable OBJECT-TYPE
SYNTAX SEQUENCE OF IfTestEntry
MAX-ACCESS not-accessible
STATUS deprecated
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."
