REVISION "200309190000Z" -- September 19, 2003 DESCRIPTION "Updated to include support for 10 Gb/sec interfaces. This resulted in the following revisions: - Updated dot3StatsAlignmentErrors and dot3StatsSymbolErrors DESCRIPTIONs to reflect behaviour at 10 Gb/s - Added dot3StatsRateControlAbility and dot3RateControlStatus for management of the Rate Control function in 10 Gb/s WAN applications - Added 64-bit versions of all counters that are used on high-speed ethernet interfaces - Added object groups to contain the new objects - Deprecated etherStatsBaseGroup and split into etherStatsBaseGroup2 and etherStatsHalfDuplexGroup, so that interfaces which can only operate at full-duplex do not need to implement half-duplex-only statistics - Deprecated dot3Compliance and replaced it with dot3Compliance2, which includes the compliance information for the new object groups In addition, the dot3Tests and dot3Errors object identities have been deprecated, since there is no longer a standard method for using them.

Ethernet-like interfaces are typically built out of several different chips. The MIB implementor 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.

In either case, the currently operating duplex mode is reflected both in this object and in ifMauType. Note that this object provides redundant information with ifMauType.
