Customizing DLSw Services

Each DLSw SAP Table entry has a unique hexadecimal value. The default SAP

Table includes SAPs 00, 04, 08, and 0C (hexadecimal). This is sufficient for most

SNA applications. To support NetBIOS, edit the DLSw NetBIOS Support

parameter and specify Yes to add SAP F0 to the table.

Figure 4-2

shows a sample network with three routers running DLSw. This

network uses the following values in the SAP Tables:

• Router A, the central site router, supports both SNA and NetBIOS traffic.

SNA session traffic uses SAP 04, and NetBIOS traffic uses F0. Additionally,

SNA requires SAP 00 for session initiation. These hexadecimal values

(00, 04, F0) must exist in the SAP Table.

• Router B, the remote site, supports NetBIOS traffic only. SAP F0 is the only

required entry in the SAP Table. By default, the SAPs 0x004, 0x008, and

0x00C appear in the table.

• Router C, a regional site, supports SNA traffic only. In this example, SNA

requires SAPs 00 and 04 in the SAP Table.

Note that SNA traffic can use other SAPs. Most SNA traffic uses SAP 04.
