- -- Changes to rfc1650 - EtherLike-MIB
- -- removed extra commas in the IMPORTS clause
- -- changed "ACCESS" to "MAX-ACCESS" for dot3StatsIndex
- -- changed value of STATUS from mandatory to current
- -- for dot3StatusIndex
- -- added imports for transmission
- -- changed value for SYNTAX clause of dot3StatsIndex
- -- to match that for IfIndex
- -- removed the following from the IMPORTS clause which
- -- were imported, but not referenced:
- -- Gauge32, TEXTUAL-CONVENTION,
- -- PhysAddress, ifEntry
- -- syntax of dot3StatsIndex changed from INTEGER to
- -- Integer32 (1..2147483647)
- -- syntax of dot3CollCount changed from INTEGER (1..16)
- -- to Integer32 (1..16)
- --
- -- !! NOTE: improper modifications were done to table dot3CollTable
- -- One result is that object group etherCollisionTableGroup
- -- contains the now "non-accessible" object dot3CollCount

- DESCRIPTION
- "This object contains an OBJECT IDENTIFIER

- interfaces are typically built out of

- is presented with a decision of which chip
- to identify via this object. The implementor
- should identify the chip which is usually
- called the Medium Access Control chip.
- If no such chip is easily identifiable,
- the implementor should identify the chip
- which actually gathers the transmit
- and receive statistics and error
- indications. This would allow a
- manager station to correlate the
- statistics and the chip generating
- them, giving it the ability to take
- into account any known anomalies
- in the chip."

- -- A TDR test returns as its result the time interval,
- -- measured in 10 MHz ticks or 100 nsec units, between

- -- detection of a collision or deassertion of carrier. On
- -- successful completion of a TDR test, the result is

- -- MIB object dot3TestTdrValue, and the OBJECT IDENTIFIER
- -- of that instanceis stored in the corresponding instance
- -- of ifExtnsTestCode (thereby indicating where the
- -- result has been stored).
- -- Loopback Test
- -- Another test is the full-duplex loopback test.
- -- This test configures the MAC chip and executes
- -- an internal loopback test of memory, data paths,
- -- 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
