Public Networks

Add this planning information to the Public Networks Worksheet.

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 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 10/03 Concepts Guide.
