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. ....................... Twinax Line description .......................
