Using multiple protocol stacks with LLI drivers

Although all SCO OpenServer networking stacks can coexist on the same machine, you may need more than one adapter to make them work together. The question of whether a single adapter is adequate to service multiple stacks depends upon the type of framing your stacks use. At present, SCO OpenServer transport stacks use either 802.3 or Ethernet II framing. NetBEUI uses 802.3 framing and TCP/IP uses Ethernet II framing. IPX/SPX can be set to use either Ethernet II or 802.3 framing.

Two rules determine whether multiple transport stacks can use the same networking adapter. The rules apply to both Ethernet and Token-Ring adapters.

• Only one 802.3 stack can use an LLI at a time. If you intend to use two or more 802.3 stacks and the network adapter uses an LLI driver, you must use one networking adapter per 802.3 stack.

• Any number of Ethernet II stacks can share the same networking adapter with one 802.3 stack.
