What Is A Bypass Tap?
When an IPS or other Inline Appliance is installed behind a V-Line™ Tap, the Tap continually checks the status of the appliance and if it is online, will direct traffic through it.
If the appliance goes for maintenance or update, or any reason, the Tap will automatically bypass the appliance and direct traffic straight through to the network.
When the appliance comes back online, the status is detected by the Tap and traffic is once again directed through the appliance.
How does the TAP detect if the appliance is online?
Heartbeat packets are injected into the traffic stream and are directed to the monitoring device.
If the Heartbeat packets are not detected when the traffic is passed back through the V-Line™ TAP on their way back to the network, the TAP enters Bypass mode and bypasses the appliance.
Heartbeats are configurable for maximum flexibility and Heartbeat packets are NEVER sent on to the live network.
