Ethernet

A full description of Ethernet is beyond the scope of this document; some basic information on Ethernet and it's use with NetBIOS is given below.

Four types of Ethernet frames are in common use. For convenience the notation used by Novell is used to describe the four Ethernet frame types:

Ethernet_802.3

Known as Ethernet 802.3 raw, this frame type is used in NetWare networks and was the default type in NetWare v2.x and v3.x

Ethernet_II

Known as Ethernet DIX (Developed by Digital Intel Xerox)

Ethernet_802.2

IEEE Ethernet

Ethernet_SNAP

SNAP (Sub-Network Access Protocol) derived from the Ethernet 802.2 structure

Ethernet_802.3

Known as Ethernet 802.3 raw, this frame type is used in NetWare networks and was the default type in NetWare v2.x and v3.x Because of the nature of these frames they are unlikely to carry NBF frames, unless encapsulated in IPX.

Ethernet_802.2

NBF frames are found in Ethernet_802.2 frames more than in other Ethernet frames when NBF is implemented "on the wire" rather than encapsulated.

Ethernet_802.2 frames are also used with IPX/SPX and FTAM (File Transfer Access and Management) protocol.

Ethernet_SNAP

Ethernet_SNAP frames are used by IPX/SPX, TCP/IP and AppleTalk Phase II.

Ethernet_II

Ethernet_II frames are used with IPX/SPX TCP/IP AppleTalk Phase I

For SNA communications the value registered for the type is 0x80D5. This value of 0x80D5 is also used for other systems using the IEEE 802.2 API including NetBIOS

Many manuals and documents describe Ethernet in detail including Novell's Guide to NetWare LAN Analysis
