Abstract:
The media access control characteristics for the Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) access method for shared medium local area networks are described. The control characteristics
for full duplex dedicated channel use are also described. Specifications are provided for MAU types
1BASE5 at 1 Mb/s; Attachment Unit Interface (AUI) and MAU types 10BASE5, 10BASE2, FOIRL (fiber optic
inter-repeater link), 10BROAD36, 10BASE-T, 10BASE-FL, 10BASE-FB, and 10BASE-FP at 10 Mb/s; Media
Independent Interface (MII) and PHY types 100BASE-T4, 100BASE-TX, 100BASE-FX, and 100BASE-T2 at
100 Mb/s; and the Gigabit MII (GMII) and 1000BASE-X PHY types, 1000BASE-SX, 1000BASE-LX, and
1000BASE-CX, which operate at 1000 Mb/s (Gigabit Ethernet) as well as PHY type 1000BASE-T. Repeater
specifications are provided at each speed. Full duplex specifications are provided at the Physical Layer for
10BASE-T, 10BASE-FL, 100BASE-TX, 100BASE-FX, 100BASE-T2, and Gigabit Ethernet. System considerations
for multisegment networks at each speed and management information base (MIB) specifications and
additions to support Virtual Bridged Local Area Networks (VLANs) as specified in IEEE P802.1Q®are also provided.
Also specified is an optional Link Aggregation sublayer which multiple physical links to be aggregated
together to form a single logical link.

35. Reconciliation Sublayer (RS) and Gigabit Media Independent Interface (GMII)
This interface has the following characteristics:
a) It is capable of supporting 1000 Mb/s operation.
