The configuration information for all SNALinks on a machine is stored hierarchically, referenced by the SNALink name, as shown in the figure below.
The entry for each SNALink must include certain fields that are required by the Microsoft® SNA Server system. These are:
| TYPE | The type of the SNALink. Acceptable values for TYPE are: SDLC, X25, TOKENRING, DFT, TCPIP, FRAMERELAY, CHANNEL, ISDN, ETHERNET.
|
| LINKMODULE | The name of the IHV DLL that provides the protocol code. |
The remainder of the configuration information consists of entries of the form PARAMETER = VALUE. Parameters can be set to either an integer or a string.
Examples of possible parameters that may be required by an SNALink are:
Note that to support more than one port on a multiport adapter, you must define multiple SNALinks. It is not possible to configure a single SNALink to support more than one physical link.
The following illustration shows a sample configuration for a machine with two SNALinks—SDLC1 and X25HOST.
The configuration information is accessed using SNA Server-provided API calls.
The IHV Setup utility must write the configuration information for each SNALink supported. Refer to Setup Information for details of how this should be performed.
