A.7.2 GLS Setup Worksheet

If you will be using Global Link Services (GLS), use the GLS Setup Worksheet to organize the input items beforehand.

This section describes the worksheet settings for the following typical duplexing modes:

• NIC switching mode (logical IP takeover)

• Fast switching mode

• GS/SURE linkage mode

See

• For configuration instructions for other duplexing modes, see "Appendix B Examples of Setting Up" in the "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function" and "Chapter 3 Configuration" in the "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Multipath Function."

• For information on the items in this sheet, see the explanation at the bottom of the sheet and "6.2 Initial GLS Setup." Also see "A.10.2 GLS Setup Worksheet" in "A.10 System Design Examples."
