Local node ID

8 hexadecimal digits (defaults to node name)

In a VTAM configuration, the first three digits should match the IDBLK parameter in the PU definition, and the last five should match the IDNUM parameter.

On an AS/400 system, the node ID is configured in the EXCHID parameter.

2 hexadecimal digits:

  • C1 for point-to-point
  • 0xFF for primary switched outgoing (destination address unknown)
  • Unique addresses for primary to multi-drop

On a VTAM host, the poll address is configured as the ADDR= parameter in the VTAM PU definition.

On an AS/400 system, the poll address is the STNADR parameter of the Line Description.
