Setting Global Interface Options for Master Engines

The Interface Options dialog contains the settings for selecting which IP addresses are used in

particular roles in system communications (for example, in communications between the Master

Engine and the Management Server). Only IPv4 addresses are used in system communications.

 To set global interface options for a Master Engine

1. Click Options. The Interface Options dialog opens.

2. Select the interface options as explained in the table below.

3. Click OK.

The interfaces you have defined are shown as a tree-table on the Interfaces tab. Global

interface options have codes in the tree-table:

• “C” and “c” are the interfaces that have the Primary and Secondary Control IP addresses

• “H” and “h” are the Primary and Secondary Heartbeat Interfaces

• “O” is the default IP address for outgoing connections

Double-click to edit the interface. Make sure you do this at the correct level for the properties

you want to edit.

Option Explanation

Control Interface

Select the Primary control IP address for Management Server contact.

(Optional) Select a Backup control IP address that is used if the Primary control

IP address is not available.

Heartbeat Interface

Select the Primary Heartbeat Interface for communications between the nodes.

We recommend that you use a Physical Interface, not a VLAN Interface. We

strongly recommend that you do not direct any other traffic through this interface.

A dedicated network helps ensure reliable and secure operation.

Caution! Primary and Backup Heartbeat networks exchange confidential

information.

Select a Backup Heartbeat Interface that is used if the Primary Heartbeat

Interface is unavailable. It is not mandatory to configure a Backup Heartbeat

Interface, but we strongly recommend it. If heartbeat traffic is not delivered, the

cluster cannot operate and traffic will be disturbed. We strongly recommend that

you use a dedicated interface for the backup heartbeat as well.

Caution! Primary and Backup Heartbeat networks exchange confidential

information.

Default IP Address

for Outgoing Traffic

This option defines the IP address that the nodes use if they have to initiate

connections (system communications, ping, etc.) through an interface that has

no IP Address. You must select an interface that has an IP address defined for

all nodes.
