Simultaneous passive access to aggregated full-duplex traffic

Keysight's 10/100/1000 Copper Tap Port Aggregator provide ultra-efficient access to critical links. This pioneering technology enables any two devices to simultaneously monitor a full-duplex link — using only one NIC per device.

Typically, full-duplex monitoring with a network tap requires two NICs, one interface for each side of the tapped full-duplex connection (or a dual channel NIC). The Copper Tap Port Aggregator combines and regenerates these streams, sending all aggregated data out two separate passive monitoring ports.

Simple to Deploy

Our Tap Port Aggregator is a simple plug-and-play solution addressing the fact that many monitoring systems, including most software based solutions, only offer a single channel NIC, limiting full-duplex visibility.

While adding a second NIC can help maintain data integrity and visibility, there is a trade-off in flexibility and ease-of-use. An operating system and NICs that enable binding are often required to achieve the same functionality of the Tap Port Aggregator. In contrast, the Tap Port Aggregator requires no additional components or configuration on the monitoring devices.

Security and Visibility

Without an IP address, monitoring devices are isolated from the network, dramatically reducing their exposure to attacks. However, the monitoring device connected to the Tap still sees all full-duplex traffic as if it were inline, including Layer 1 and Layer 2 errors.


For extra uptime protection, our Taps offer redundant power connections. Should the primary power source fail, the Tap automatically switches to the backup power source.
