Deprecated Definitions - Objects
Interface Test Table
This group of objects is optional and deprecated. However, a media-specific MIB may make
implementation of this group mandatory. This table replaces the ifExtnsTestTable.

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 cannot 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:
