This configuration is recommended. It is similar to the setup configuration, but for
fault-tolerant redundancy, it includes a second maintenance switch, backup system
console, and modem. The maintenance switches provide a dedicated LAN in which all
nodes use the same subnet.
Note. A subnet is a network division within the TCP/IP model. Within a given network, each
subnet is treated as a separate network. Outside that network, the subnets appear as part of a
single network. The terms subnet and subnetwork are used interchangeably.
