write access to this object is required to keep the value in

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."
