For the SK-NET GE dual link types:
Redundant Link Management (RLMT) for Fault Tolerance
The two Gigabit Ethernet ports offer dual homing similar to that found in FDDI technology. In order to
provide greater fault tolerance the Gigabit Ethernet Server Adapter is connected to two switch ports.
These ports may be on the same switch or on two switches in different physical locations. Only one
port is active at any one time but both links are monitored. The second port is simply in standby
mode. If the active link fails, the second port automatically takes over the connection. This means
that the server connection is protected against the failure of a port on the switch, failure of a port on
the network card and failure of a cable.
