PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function 4.1 (for Linux)

2.2.5 Configuring single physical interface

You can create a virtual interface, which has a single physical interface. This function enables failover because of a line failure even on a cluster system that has only one physical interface available for use.

Figure 2.17 shows an example of single physical interface configuration.

• This feature is capable for Fast switching mode and NIC switching mode.
• The selection criteria of a mode where a single physical interface is used on GLS relies on the mode where redundant line is used. Refer to the fault monitoring function requirements section on "1.1.1 Functional comparison" before selecting a single physical interface for either mode.
