Basic operation

This topic describes the basic operating principles of the Network Active Bypass unit.
Typical deployment
The following diagram shows how the data is transferred from the network to the Network IPS through
the Network Active Bypass unit, and highlights the associated functions handled at each stage of bypass
switching.
Switching modes
The Network Active Bypass unit provides two switching modes:

1G Network Active Bypass: User Guide
Description
Active mode channels Ethernet frames between the
public network and the private network through the
Network IPS appliance. Typically, data flows from the
public network to port N1 (network in). The Network
Active Bypass unit transfers the data to port A1
(appliance in) and then routes the data through the
Network IPS appliance to port A2 (appliance out). Active
switching then routes the data through port N2 and out
to the private network.
Active mode also operates in reverse, routing data from
a private network to a public network.
