SNA Server Doesn’t Support Digi Cards w/ SDLC and X.25 Driver

ID: Q163522

The information in this article applies to:

Microsoft SNA Server, versions 2.0, 2.1, 2.11, and 2.11 Service Pack 1 (SP1)

SYMPTOMS

SNA Server versions 2.0, 2.1, 2.11, and 2.11 Service Pack 1 do not support the use of a Digi card over the IBM SDLC and X.25 link services.

CAUSE

The two main limiting factors for using Digi cards with the IBM x.25 and the SDLC link services are:

the lack of provision for multiple link services accessing the same instance of the driver.
the need to support significantly larger BTU sizes.

STATUS

An update to SNA Server is available; it was modified to enable support of Digi cards with the IBM SDLC and X.25 link services.

Microsoft has confirmed this to be a problem in SNA Server versions 2.0, 2.1, 2.11, and 2.11 SP1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
