6.1.2 Frame Types

IPX can run on top of four different frame types on the Ethernet. These frame types are 802.2,
802.3, Ethernet II (DIX), and SNAP (Sub-Network Access Protocol). Each frame type is a
separate logical network, even though they exist on one physical cable.
Although there are four frame types available on the Ethernet, you should configure as few frame
types as possible on your NetWare server and use automatic frame detection on the clients to
simplify management and to reduce network overhead.

6.1.3 External Network Number

Each of the four logical networks (based on frame type) has its own external network number.

6.1.4 Internal Network Number

In addition to the external network numbers, each NetWare server has its own internal network
number that is a virtual network to which the server is attached. It is important to remember that
every network number must be unique for that entire internetwork, either internal or external.
