A network TAP (test access point) is a monitoring device that mirrors the traffic that is passing between network nodes. A TAP is a hardware device inserted at a specific point in the network to monitor specific data. As an essential part of the Gigamon Visibility and Analytics Fabric™, network TAPs acquire traffic to provide the visibility required to secure, monitor and manage your enterprise's network infrastructure continuously and efficiently.
How Taps Work
A TAP monitors one network connection and generally comes with four ports: network A port, network B port, monitor A port and monitor B port. TAPs allow network traffic to flow through the device’s network A and B ports uninterrupted, while simultaneously copying the same data to the monitor A and B ports. The monitor ports can feed tools such as VoIP recording devices, network intrusion detection and prevention systems, network analytics, protocol analyzers, packet sniffers and traffic aggregation/packet broker systems.
