Sample Twinax Configuration for SNA Server
ID: Q152783
|
The information in this article applies to:
-
Microsoft SNA Server, versions 2.11, 3.0
on the following platforms: NT
SUMMARY
SNA Server supports twinax connections to AS/400s. SNA Server bundles both
the IBM and Andrew drivers.
The maximum connections per adapter = 1.
The maximum sessions per connection = 512.
MORE INFORMATION
Setup is the same on AS/400 for both IBM and Andrew adapters, and it is
identical to the configuration for PC Support over twinax adapters.
NOTE: The AS/400s can autoconfigure these settings, if permitted in AS/400
system settings. This is the least troublesome way to configure the
connection. On the AS/400, you must configure an APPC "logical" controller
and device in addition to the twinax-attached "physical" controller. The
APPC resources are necessary to support APPC sessions over twinax (which is
the only way SNA Server can communicate with the AS/400). The same APPC
resources are used to support a connection to the AS/400 via 802.2 or SDLC
from the same SNA server.
The following examples represent an AS/400 display, as configured for a
twinax adapter.
NOTE: A "<<==" represents matching SNA Server parameters or other pertinent
information.
