Configuring SNA Ports 7-17
SNA Status and Configuration
Retry Sequence Repeat Count
This Þeld speciÞes the number of times a retry sequence will be repeated for the
local SDLC link station. The default value for this parameter is 0.
RNR Limit
This speciÞes the length of time (in 1/100ths of a second) an SDLC link station
will allow its adjacent link station to remain in a busy (RNR) state before
declaring it inoperative. A value of 0 means there is no limit. The default value for
this parameter is 18000.
Group Poll Address
This Þeld deÞnes the group poll address for this link station. If group poll is not in
effect for this link station, the value should be 0.
Desired Operational State
This is the desired state of the SDLC station, Active or Inactive. The default value
for this parameter is Active.
Desired State at Startup
This is the desired state at startup of the SDLC station, Active or Inactive. The
default value for this parameter is Active.
Modulus
This parameter speciÞes the modulus for the SDLC link station. The modulus
determines the size of the rotating acknowledgment window used by the SDLC
link station pair. The default value for this parameter is 8.
Data Mode
Use this Þeld to specify whether communications mode with the adjacent link
station is Half (two-way alternate) or Full (two-way simultaneous). The default
value for this parameter is Half.
Support SIM, RIM Frames
This parameter determines whether the link station supports transmission and
receipt of Set Initialization Mode (SIM) and Request Initialization Mode (RIM)
control frames. The default value for this parameter is
No .
Transmit-Receive Capabilities
This parameter controls the transmit-receive capabilities for this link station,
two-way alternating (twa) or two-way simultaneous (tws). The selected value
establishes the value of the transmit-receive capability indicator sent in the XID
image to the adjacent link station.
