2.1. Tap function

Each Tap unit faithfully copies all incoming traffic to the RJ45 ports (Network A and Network B) at the same network speed (10/100/1000 BASE-T).

The Tap monitors the seven OSI layers and duplicates:

• Packs of all sizes and types

• Low-level errors and VLAN traffic

The GTap is not configurable and therefore has no management/administration interface.

The GTap does not memorize traffic.

The GTap is non-intrusive and therefore does not disrupt the traffic to be replicated.

The GTap has no IP address and isolates the network to be monitored from the monitoring device.

Once in place, the GTap enables monitoring devices to be connected and disconnected at will, with no impact on the network link to be monitored.

2.1.1. Link Failure Propagation (LFP)

The GTap transmits link failure errors between ports automatically, allowing the network to activate a redundant path, while the Tap stays available for autonegotiation.

The LFP ensures less downtime, and is essential for high availability networks.
