In Example 4, the driver's class table associated with a particular LANIC card is displayed. This table shows the system class numbers posted to even"numbered SAPs identifying programs that intend to receive packets from this card.

The table is organized such that the numbers on the left indicate the range of SAPs covered in that row. For example, the second row contains class numbers for SAPs 16, 18, 20, 22, 24, 26, 28, and 30. For this row, there are no class numbers posted to these SAPs.

For this particular node, the table reflects that only one class number is posted. The Node Manager software's class number 3391, assigned by the system, is posted to SAP F8 hex (248 decimal).

By definition, there are no odd"numbered SAPs. A received packet containing an odd DSAP is a Group DSAP packet. The driver routes Group DSAP packets to the program whose class number is posted to a special program code •7" (not reflected in the display above).

Note

Node Manager software does not handle Group DSAP packets. For Group DSAP packet handling, a user"written program is required. Refer to the

HP 12079A Direct Driver Access Manual product, part number 12079"90001, for further information.
