This article was previously published under Q147625 SUMMARY
When you configure a connection using an Eicon Technologies V3R3 SDLC Link
Service, make sure that all parameters are set up correctly in the WAN
Services Configuration software. The parameters are also available in
Connection Properties of the SNA Server Admin, but they do not over-ride
the parameters set in the WAN Services Configuration software.
MORE INFORMATION
The following Advanced Connection Properties parameters of SNA Server Admin
on SNA Server 2.x, or the SDLC and Address tab in the Connection Properties
in SNA Server manager on SNA Server 3.0 are ignored by the Eicon WAN
Services SDLC Link Service:
- Encoding (NRZ/NRZI)
- Duplex (Half/Full)
- Idle Timeout
- Idle Retries
- Data Rate (Low/High)
The following parameters are not ignored. However, the configuration in the
WAN Services takes precedence.
- Max BTU Length (Frame Size N1)
- Timers
- Retry Counters
Any Discrepancies between the values displayed in SNA Server and the values
in the Eicon SDLC card generally result in unreliable connections. For
example, if the Max BTU Length (Frame Size N1) is set to a small value in
the WAN Services Configuration software, the connection becomes active, but
you are unable to connect to the LUs. This is due to problems with the BTU
size for the LU.
If connecting to a host using the Microsoft 3270 emulator, you will receive
the following error at the bottom of the applet after trying to start a
session:
Host Communications Link Error. Session Lost.
The following error will also be displayed in the application
log of the event viewer:
Event ID 23:
Connection <connection_name> using Link Service <link_service_name> failed.
Qualifier = 0015
SUBCODE INFORMATION: X'1152'
The Eicon WAN Services Configuration program is in the WAN Services
Configuration Program group. In addition, if you use the link service
included in SNA Server Service 2.11 Service Pack 1, click Advanced in the
link service configuration window to the run the WAN Services Configuration
program. After you make any changes in the program, reboot the computer.
For more information, look at Chapter 5 of the Eicon WAN Services for NT
System Guide or WANNT.HLP included in the Eicon V3R3 Drivers and Link
Service software.
