SNA Node and Link Configuration
Configuring the SNA Node and Link
If you are configuring a node for SNA/X.25 Link, you
must enter 2.0 in this field.
If you are configuring a node for SNA/Token Ring Link,
enter 2.1 in this field.
Values: 2.0 and 2.1
Default: 2.0
Host Configuration:
• SNA/SDLC (dependent LU): The PUTYPE operand of
the PU macro must be set to 2, and the XID operand
of the same PU macro must be set to NO or not
specified at all.
• SNA/SDLC (independent LU): The PUTYPE operand
of the PU macro must be set to 2, and the XID
operand of the same PU macro must be set to YES.
• SNA/X.25 (PVC): The PUTYPE operand of the X25.PU
macro must match this field; see Table 2-2.
• SNA/Token Ring (dependent and independent LUs):
The PUTYPE operand of the PU macro must be set to
2, and the XID operand of the same PU macro must
be set to YES.
Node 2.1 Dependent LU Support
If you entered 2.0 in the Node Type field, this field
must be blank. If you entered 2.1 in the Node Type
field and one or more dependent LUs are configured,
enter Y. If you entered 2.1 in the Node Type field and
no dependent LUs are configured, enter N.
Default: Blank (the node is T2.0)
Physical Unit Data
Information about the Physical Unit (PU).
MAX DATA Required. The maximum size, in
bytes, of the transmission buffers
(frames) used to hold data for the
SDLC connection, the X.25 QLLC
connection, or token ring connection.
Range: 137-2057 (integer)
Default: 265
