Public Network FAQ

• What public network adapters does Sun Cluster support?

  Currently, Sun Cluster supports Ethernet (10/100BASE-T and 1000BASE-SX Gb) public network adapters. Because new interfaces might be supported in the future, check with your Sun sales representative for the most current information.

• What is the role of the MAC address in failover?

  When a failover occurs, new Address Resolution Protocol (ARP) packets are generated and broadcast to the world. These ARP packets contain the new MAC address (of the new physical adapter to which the node failed over) and the old IP address. When another machine on the network receives one of these packets, it flushes the old MAC-IP mapping from its ARP cache and uses the new one.

• Is Sun Cluster supported to set local-mac-address?=true in the OpenBoot PROM for a host adapter?

  No, this variable is not supported.
