Highly-available Deployment
Use optical bypass switches with the P-Series for a highly-available, redundant deployment, as shown in
Figure 6 . Both the appliances have the same configuration so that in the event of a power failure on one
device, the other continues to operate, and the detection engine remains intact. In the event that both
devices experience a power failure, the traffic continues to flow through the bypass switches.

Passive Deployment
Enable passive mode (see Command Line Reference on page 79 ) with fiber taps in line for IDS
deployments.
• Send traffic from one side of the tap to port P0 and traffic from the other side to port P1, as shown in
Figure 7 .
• Aggregate traffic from both sides of the link to one port, as shown in Figure 8 .
• Aggregate traffic from both sides of the link to one port using a SPAN port, as shown in Figure 9 .
