esigning and implementing high-availability Ethernet LAN topologies in 
networks can be challenging. Traditionally, the choices for redundancy for 
edge of the network devices were too limited, too expensive, and too 
complicated to be considered in most networks. Redundancy at the edge of 

the network is greatly simplified by the using dual-homing.

In
re

 Ethernet LANs, dual-homing is a network topology that adds 

liability by allowing a device to be connected to the network by 

way of two independent connection points (points of attachment). 

One connection point is the operating connection, and the other is a standby or back-up 
connection that is activated in the event of a failure of the operating connection. A dual-
homing switch (such as EDS42) offers two attachments into the network or two 
independent media paths and two upstream switch connections. In the case of the 
Magnum 6K family of switches, any two ports can be defined as dual-home ports to 
provide this level of redundancy. Loss of the Link signal on the operating port connected 
upstream indicates a fault in that path, and traffic is quickly moved to the standby 
connection to accomplish a fault recovery.
