Figure 3-6 Example Of Lan Port Connections Made Redundant - Sun Microsystems Sun SPARC Enterprise M3000 User Manual

In the example of the configuration shown in
the two LAN ports and its switch hub, its LAN is replaced by the other LAN.
Moreover, if an error occurs in the switch hub, the other LAN can be relied on for
notification.
If an error occurs in the active XSCF Unit in the systems with two XSCF Units, XSCF
generates a failover, then the LAN of the other XSCF Unit can be used.
