Configuring Active/Passive Failover Between Two Systems
When two Equalizers are configured into Active/Passive failover, they form a "failover pair". An
Equalizer in a failover pair is called a "peer". At any given time, only one of the Equalizers in a
failover pair is actually servicing requests sent to the cluster IP addresses defined in the
configuration -- this unit is called the "active peer" or the "current primary" in the failover pair.
The other Equalizer, called the “passive peer” or "current backup", does not process any client
requests.
Both units continually send "heartbeat probes" or "failover probes" to one another. If the current
primary does not respond to heartbeat probes, a failover occurs. In this scenario the current
backup assumes the primary role by assigning the cluster IP addresses to its network interfaces
and begins processing cluster traffic.
Configuration of failover peer definitions and options on VLAN subnets can be performed through
the CLI or the GUI.
The figure below shows the suggested sequence of steps for enabling both Active/Passive Failover
and the preliminary steps for configuring Active/Active and N+1 Failover.
