For ethernet-like interfaces, this test-- configures the MAC chip and executes an internal loopback-- test of memory and the MAC chip logic. This loopback test can
-- only be executed if the interface is offline. Once the test-- has completed, the MAC chip should be reinitialized for network-- operation, but it should remain offline.-- If an error occurs during a test, the object ifExtnsTestResult-- (defined in RFC 1229) will be set to failed(7). The following-- two OBJECT IDENTIFIERs may be used to provided more-- information as values for the object ifExtnsTestCode in-- RFC 1229:dot3Errors OBJECTIDENTIFIER::={ dot3 7}

-- exception of 10BaseT and 10BaseF, is Time-domain Reflectometry (TDR).-- The TDR value may be useful in determining the approximate distance-- to a cable fault. It is advisable to repeat this test to check for-- a consistent resulting TDR value, to verify that there is a fault.dot3Tests OBJECTIDENTIFIER::={ dot3 6}dot3TestTdr OBJECTIDENTIFIER::={ dot3Tests 1}-- A TDR test returns as its result the time interval, measured
-- in 10 MHz ticks or 100 nsec units, between the start of-- TDR test transmission and the subsequent detection of a-- collision or deassertion of carrier. On successful completion-- of a TDR test, the appropriate instance of ifExtnsTestResult-- contains the OBJECT IDENTIFIER of the MIB object which-- contains the value of this time interval.
