- -- 802.3 Tests
- -- The ifExtnsTestTable defined in RFC 1229 provides a common
- -- means for a manager to test any interface corresponding to
- -- a value of ifIndex.
- -- At this time, one well known test (testFullDuplexLoopBack) is
- -- defined in RFC 1229. 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 OBJECT IDENTIFIER ::= { dot3 7 }
- -- couldn't initialize MAC chip for test
- dot3ErrorInitError OBJECT IDENTIFIER ::= { dot3Errors 1 }
- -- expected data not received (or not
- -- received correctly) in loopback test
- dot3ErrorLoopbackError OBJECT IDENTIFIER ::= { dot3Errors 2 }
- -- Tests
- -- TDR Test
- -- Another test, specific to ethernet-like interfaces with the
- -- 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 OBJECT IDENTIFIER ::= { dot3 6 }
- dot3TestTdr OBJECT IDENTIFIER ::= { 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.
- -- 802.3 Hardware Chipsets
- -- The object ifExtnsChipSet is provided in RFC 1229 to identify
- -- the MAC hardware used to communcate on an interface. The
- -- following hardware chipsets are provided for 802.3:
- dot3ChipSets OBJECT IDENTIFIER ::= { dot3 8 }
- dot3ChipSetAMD OBJECT IDENTIFIER ::= { dot3ChipSets 1 }
- dot3ChipSetAMD7990 OBJECT IDENTIFIER ::= { dot3ChipSetAMD 1 }

- dot3ChipSetFujitsu86950 OBJECT IDENTIFIER ::=
- { dot3ChipSetFujitsu 1 }

- -- assignment is required in other documentation, e.g., assignment
- -- within that part of the registration tree delegated to
- -- individual enterprises (see RFC 1155).
