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

• 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.
