How to Configure an IPDLC Link Service

  • Artigo

  1. Retrieve the command prompt instructions.

  2. If necessary, retrieve the adapter name.

  3. Create the link service.

  4. Create the independent session.

    The following code sample describes how to configure an IPDLC link service. The following table describes the relevant command prompt switches:

Command line switch Description
-p PrimaryNNS: the Primary Network Node Server
-b (Optional) BackupNNS: Backup Network Node Server
-d (Optional) device: Overrides the adapter name discovered
-l (Optional) LenNode: Used to configure the LEN node (default is 1st)
