Table 7.3 shows a sample IBM 9370 VTAM definition for four SDLC lines. The LLGROUP label shows the VTAM definitions for lines B80 and BB0 of a leased group. The SNAGROUP label shows the VTAM definitions for lines B90 and BA0 of a switched group.

Table 7.5 describes key parameters shown in Tables 7.3 and 7.4.
Table 7.5 VTAM Parameter Descriptions for SDLC
VTAM parameter | Corresponding SNA Server parameter |
|
ADDR= | Poll Address (advanced SDLC setting) | A two-digit hexadecimal value that identifies the control unit that the host uses to poll. |
IDBLK= | First three digits of Local Node ID (basic connection setting) | A three-digit hexadecimal value that, together with IDNUM, identifies the SNA Server. The values 000 and FFF cannot be used; these values are reserved. |
IDNUM= | Last five digits of Local Node ID (basic connection setting) | A five-digit hexadecimal value that, together with IDBLK, identifies the SNA Server. |
MAXDATA= (in the PU definition for SWPU1) | Max BTU Length (advanced SDLC setting) | The maximum length of a basic transmission unit (BTU) sent or received; BTUs are also known as I-frames. |
LOCADDR= | LU Number | The LU local address at the PU. For independent LUs that communicate with a host, the LOCADDR parameter must be set to zero. For dependent LUs with VTAM, the LOCADDR must be at least 2. Also, for dependent LUs, the LU Numbers set in SNA Server must match the LOCADDR values on the host. |
The DLOGMOD values shown in the example are the logon mode table entries from the mode table. For a complete listing of default mode table entries, see the documentation for your IBM product.
