Public Networks

Add this planning information to the “Public Networks Worksheet” in Sun Cluster 3.1 Release Notes.

Public networks communicate outside the cluster. Consider the following points when you plan your public network configuration.

• Public networks and the private network (cluster interconnect) must use separate adapters.

• You must have at least one public network that is connected to all cluster nodes.

• You can have as many additional public network connections as your hardware configuration allows.

• The local-mac-address? variable must use the default value true for Ethernet adapters. Sun Cluster 3.1 software does not support a local-mac-address? value of false for Ethernet adapters. This requirement is a change from Sun Cluster 3.0, which did require a local-mac-address? value of false.

See also IP Network Multipathing Groups for guidelines on planning public network adapter backup groups. For more information about public network interfaces, see the Sun Cluster 3.1 Concepts Guide.
