Cabling Requirements

The two appliances in the high availability pair are installed onto the same subnet in either a parallel arrangement or a one-arm arrangement, both of which are shown in the following figure. In a one-arm arrangement, use the apA.2 port (and, optionally, the apB.2 port), not the apA.1 port. Some models require a separate management LAN, whether deployed in inline or one-armed mode. This is depicted only in the middle diagram.

Figure 1. Cabling for High-Availability Pairs

Cabling for High-Availability Pairs Do not break the topology with more switches. Random switch arrangements are not supported. Each of the switches must be either a single, monolithic switch, a single logical switch, or part of the same chassis.

If the spanning-tree protocol (STP) is enabled on the router or switch ports attached to the appliances, failover works, but the failover time can increase to roughly 30 seconds. Failover time is roughly five seconds without STP. Therefore, to achieve the briefest possible failover interval, disable STP on the ports connecting to the appliances.
