Generic-Interface MIB Extensions (RFC 1229)
This generic-interface MIB is an experimental MIB that provides extensions to the
generic interface group defined in MIB II. This MIB describes three tables:
 Generic Interface Extension Table
 Generic Interface Test Table
 Generic Receive Address Table
Only the generic interface test table is supported by the DSU/CSU. This table is
supported for the network interface only.
Generic Interface Test Table, Generic Interface MIB
The test table provides access to additional tests (loopbacks and pattern tests)
that are not in the interface group of MIB II.
Generic Interface Test Table – “ifExtnsTestType” Object (ifExtnsTestEntry 4)
This object is a control variable used to start and stop operator-initiated tests on
the interface. It provides the capability to:
 Start/stop the Monitor QRSS test pattern on the network interface.
 Start/stop the Send QRSS/511 test pattern on a synchronous data port.
 Start sending a V.54/FT1 UP/DOWN code to the remote unit for a
synchronous data port.
 Start/stop the Monitor QRSS/511 test pattern on a synchronous data port.
 Start/stop the DCLB/DTLB loopback test on a synchronous data port.
The following object identifiers are used to control the tests on the interface.
 noTest – Stops the test in progress on the interface.
 testFullDuplexLoopBack – Initiates a DCLB on the interface. Only supported
for the data ports.
 testLoopDTLB – Initiates a DTLB on the interface. Only supported for the
data ports.
 testMonQRSS – Initiates a Monitor QRSS test on the interface. Supported for
the data ports and the network interface.
 testMon511 – Initiates a Monitor 511 test on the interface. Only supported for
the data ports.
 testSendQRSS – Initiates a Send QRSS test on the interface. Only supported
for the data ports.
 testSend511 – Initiates a send 511 test on the interface. Only supported for
the data ports.
