TAP 'Breakout' (often referred to as just TAP or TAP mode) is the most common function TAPs provide. 'Breakout' sends each side of traffic to separate monitoring ports. Ensuring that no packet is lost to high-priority monitoring tools.

Aggregation merges both sides of the traffic streams into one monitoring port to reduce appliance costs or consolidate packet broker ports, often used in combination with filtering TAPs, (e.g. filter and aggregate data streams).

Regeneration/SPAN creates multiple copies of network data to support multiple devices from a single tapped link. This allows you to send the same data to multiple destinations.

Filtering, usually associated with network packet brokers, allows you filter specific data streams you want tapped and monitored. Filtering also prevents ports from becoming oversubscribed during aggregation. Another feature to help optimize the function of your tools and network.

Bypass manages the availability of inline tools, preventing a single point of failure in the network by “bypassing” the device in the event it fails or needs to be updated. Reducing network downtime. Bypass is unique to the other TAP modes, as it is an inline use case not out-of-band.
