Configuring Communication Paths
3–12 iSTAR Ultra Installation and Configuration Guide
Configuring Communication Paths
This section includes guidelines and procedures for configuring primary and secondary
communication paths.
Planning Primary Communications
Configuring a primary communication path involves:

Specifying a master for the cluster

Specifying a communication methods between the master and the C•CURE host.

Specifying connection parameters for establishing and maintaining the primary path.
Primary Communication Guidelines
Follow these guidelines when configuring a primary path:

Every cluster must have a master.

Only one master is allowed per cluster.

If a cluster contains only one controller, that controller is the master.

Any controller in a cluster can be designated as the master.
Planning Secondary Communications
Configuring a secondary communications path involves:

Specifying the same controller responsible for secondary communications with the
C•CURE host via another NIC when a communications failure occurs on the primary
path.

Specifying the connection type.
