SNA Node and Link Configuration
Configuring the SNA Node and Link
to support synchronous out-dial facilities of host
computers and to support the evolution of synchronous
communications software on PCs.
Station ID
Required. This defines the HP e3000’s link station
identifier to the remote system’s communications
controller.
Range: 01–FE (hexadecimal)
Host Configuration: The ADDR operand of the PU
macro must match this field, refer to Table 2-1.
AS400 Configuration: The STNADR parameter in the
controller description must match this field, refer to
Table 2-1.
Receive Timeout T1
Required. The Receive timeout field is the current
value of the T1 timer. The T1 timer waits the specified
number of hundredths-of-seconds for a particular frame
to be acknowledged. A frame that is transmitted, but
not acknowledged, before the T1 timer expires, is
retransmitted.
Range: 1–63 seconds
Speed
Required. The Transmission Speed field displays the
current transfer rate, or clocking, configured for the
node in the NMMGR Link screen. If modems are used,
the modems will control the clocking. The ACC card
transmits at the clocking setting of the modem and
ignores the value configured in this field.
Range: 1200–2048000 bps
Number of retries N2
Required. The N2 field is the maximum number of
times a frame is retransmitted after the SDLC Parm T1
expires. The frame is retransmitted at the SDLC Parm
T1 interval for the number of times specified in this
field. When this count is depleted, the frame is
retransmitted at T1 second intervals. If no response is
received after these transmissions, the link is brought
down.
A node that is configured with the value specified in
SDLC Configuration Parameters output will attempt to
retransmit an unacknowledged frame a maximum of
