Physically adding public network adapters to a node in a cluster is no different from adding public network adapters in a noncluster environment. For the procedure about how to add public network adapters, see the hardware documentation that shipped with your node and public network adapters.
Once the adapters are physically installed, Oracle Solaris Cluster requires that they be configured in an IPMP group.
If your network uses jumbo frames, review the requirements in Public Network Hardware: Requirements When Using Jumbo Frames and see the documentation that shipped with your network interface card for information about how to configure jumbo frames.
To add a new public network adapter to an IPMP group, see Chapter 1, Administering TCP/IP Networks, in Administering TCP/IP Networks, IPMP, and IP Tunnels in Oracle Solaris 11.2 .
