Repeater Redundancy

This chapter describes how to configure and enable redundant circuits.

Setting Network Circuit Redundancy

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

NOTE

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