Switching modes
The 10G Network Active Bypass unit uses two switching modes: inline and bypass. The 10G Network
Active Bypass unit is placed inline with the Network IPS appliance and is connected to the Network IPS
appliance and to the networks.
Inline mode
When the 10G Network Active Bypass unit is in inline mode, network traffic is sent through the Network
IPS appliance. Traffic flows from the network to port N1 (network in) on the 10G Network Active Bypass
unit. The 10G Network Active Bypass unit transfers the traffic to port A1 (appliance in) and then routes
the traffic through the Network IPS appliance to port A2 (appliance out). Traffic is then routed through
the 10G Network Active Bypass unit at port N2 (network out) and out to the network. This mode also
operates in reverse, routing traffic between networks.
