2.8.2 High availability

When paired with another IPFE instance and configured with at least two Target Set Addresses, the IPFE supports high availability. In the case of an IPFE pair and two Target Set Addresses, each IPFE is configured to handle one Target Set Address. Each IPFE is automatically aware of the ruleset for the secondary Target Set Address. If one IPFE should become unavailable, the other IPFE becomes active for the failed IPFE's Target Set Address while continuing to handle its own.

In the case of an IPFE pair, but only one Target Set Address, then one IPFE is active for the Target Set Address and the other is standby.
