Interface Test Table

The unit uses the Interface Test table to provide access to additional tests such

as loopbacks and pattern tests, which are not included in the Interfaces Group of

MIB II. Interface Test Group objects are shown in Table C-5.

Table C-5. Interface Test Group Objects (1 of 2)

Object Description Setting/Contents
ifTestID
(ifTestEntry 1)
Provides a unique identifier
for the current request of
the interface’s test. Ensures
that the results of the test
are for that request. This
handles the rare condition
where another SNMP
Manager starts a test
immediately after
completion of a previous
test, but before the
previous test results are
received by the first SNMP
manager.
Set by an SNMP Manager before the
test is started. The unit then increments
the previous value. The value is then
checked after the test has completed.
ifTestStatus
(ifTestEntry2)
Indicates the test status of
the interface. Set to inUse(2) by an SNMP
Manager before a test is started.
Set to notInUse(1) by the unit when
the test has completed. Also set to
notInUse(1) by the unit if the SNMP
Manager fails to set an ifTestType
within 5 minutes.
ifTestType
(ifTestEntry 3)
A control variable used to
start/stop user-initiated
tests on the interface.
Provides the following
capabilities:
Start/stop user data port
loopback
Start/stop send pattern
on the user data port
Start/stop the monitor
test pattern on the user
data port
The following objects use identifiers to
control tests on the User Data port
interface:
noTest (0 0) – Stops the test in
progress on the interface.
testLoopDTE (ifTestType 2) – Starts
a Local Loopback (DTE) on the
interface.
testMon511 (ifTestType 4) – Starts a
Monitor 511 test on the interface.
testSend511 (ifTestType 6) – Starts a
Send 511 test on the interface.
