SNA Node and Link Configuration
Configuring the SNA Node and Link
operand of the PU macro must match
this field.
• SNA/SDLC: The MAXDATA operand of
the PU macro must match this field,
refer to Table 2-1.
• SNA/X.25 (PVC): The MAXDATA
operand of the X25.PU macro must
match this field, refer to Table 2-2.
• SNA/X.25 (SVC): The MAXDATA
macro in the VTAM switched major
node must match this field, refer to
Table 2-3.
• SNA/Token Ring: The MAXDATA
operand of the PU macro in the
VTAM switched major node must
match this field, refer to Table 2-7.
AS/400 Configuration: The
MAXFRAME
parameter in the line description must
match this field, refer to Table 2-8 and
Table 2-10.
ID BLK Required. Three hexadecimal digits
which, together with ID NUM (see
below), form the exchange identifier
usedwithexchange identification (XID)
requests. This composite identifier
must be unique within the SNA
network.
NOTE
For communication with an IBM host, this parameter (
ID BLK
) is
ignored for nonswitched lines. For communication with an IBM AS/400,
this parameter is required for both switched
and
nonswitched lines.
Range: 001-FFE (hexadecimal)
Default: 023 (ID BLK sent by the
IBM 8100)
Host Configuration:
• SNA/SDLCMUX: The IDBLK
operand of the PU macro must match
this field.
• SNA/SDLC: The IDBLK operand of
the PU macro must match this field,
refer to Table 2-1.
• SNA/X.25(SVC): TheIDBLK operand
