Repeater Redundancy

Chapter 4

Conﬁguring and enabling redundant circuits; monitoring redundant circuits

Setting Network Circuit Redundancy

The redundancy application gives you the ability to deÞne redundant circuits for your SEHI100TX to ensure that critical network connections remain operational. Each circuit has a designated primary port and one or more backup ports. The SEHI100TX monitors the link status of the primary portÕs connection to one or more network IP addresses; if the link fails, the SEHI100TX automatically switches trafÞc to a backup port.

NOTE

Before you conÞgure redundancy, make sure that only the primary physical link is connected to the network. If a backup port is connected before you conÞgure and enable redundancy, you create a data loop.
