Distributed Link Service Allows Link Type To Be Changed

Article ID: 171114

Article Last Modified on 6/24/2004



APPLIES TO

  • Microsoft SNA Server 3.0 Service Pack 4
  • Microsoft SNA Server 4.0



This article was previously published under Q171114


SYMPTOMS

The configured Link Type for a Distributed Link Service can be changed after the link service is installed, even though this should not be possible.

The Distributed Link Service configuration is not preventing the link type for a distributed link service from being changed after it was installed. The link type should not be configurable after the link service is installed, because the connection properties are different for the various connection types. For example, the connection parameters for an 802.2 DLC connection are different than the parameters for a Leased Line SDLC connection.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

S E R V P A C K


When the fix is applied, the Distributed Link Service configuration is updated to prevent the link type from being changed after a Distributed Link Service is installed with one exception. The exception is for Ethernet 802.2 and TokenRing 802.2 link types. Either one of these link types can be changed to the other, because the 802.2 DLC connection parameters are the same for either Ethernet or Token Ring connections.

MORE INFORMATION

When you are using the Distributed Link Service (DLS) feature of SNA Server, the Link Type parameter in the Distributed Link Service properties on a remote SNA Server computer is used to specify the type of link being distributed by the central SNA Server computer. For example, if the central SNA Server computer is distributing an 802.2 DLC Link Service over an Ethernet adapter, the Link Type on the Distributed Link Service would need to be Ethernet 802.2 on the remote SNA Server computer.

NOTE: A Distributed Link Service will show up in SNA Server Manager as SnaRem1, SnaRem2, and so on.

Under SNA Server 3.0 and 3.0 SP1, the Distributed Link Service Properties dialog box lists the following Link Types:

Channel Attach
DFT
Ethernet 802.2
Leased SDLC
Switched SDLC
TokenRing 802.2
Twinax
X.25/QLLC.


All of these options remain available after the link service is installed.
