FAQ

What's LFP?

Link Failure Propagation is an important feature for network Tap devices with copper ports that it relays transparent link information to the network ports. If a device connected to port A fails or a link is disabled by a network component for any reason, the LFP function shuts down the link to port B, ensuring that HA connections continue to work. If port B didn't know the link had been deactivated, then its connection would still be active and network routes and HA protocols wouldn't work properly.



What's aggregation?

Aggregation is interconnection or network data packets bundled together from either a single full-duplex link (TX & RX) or from multiple links. Aggregation allows a single network interface to analyse and evaluate the full-duplex data from one or more data links. The aggregation device receives data from the corresponding lines, adds it together in the correct order and sends the packets to one or more ports.


What's fail-safe?

Since network Taps are usually installed in critical network lines, it's important to ensure that Taps don't affect the line in any way. Using fail-safe, when there's a failure or an arbitrary deactivation, the Tap acts as a cable bridge and ensures that the active network connection isn't interrupted or at least continues to function without the Tap so the active line isn't adversely affected.


Will I lose my network connection when I change the function mode on the bypass switch (Tap)?

Garland Technology's bypass switches support aggregation, break-out & bypass functions and allow switching these functions during the network's operation with no impact on its performance.


What's a bi-directional heart-beat in relation to a bypass switch (Tap)?

Garland Technology's bypass taps support bi-directional heart-beats to check the health status of connected monitoring devices in both network directions, ensuring reliability.


Are physical errors (CRC) passed on to the monitoring tools?

These important errors are sent on for analysis for all products on the output ports.


What's the sticky function?

Should the primary device fail during operation of redundant sensors on a bypass switch (Tap) and the secondary device takes over the analysis, the Sticky function can determine which appliance should be activated when the primary system is back up again.


What's reverse bypass?

With this switch, you can specify what to do with the main network line when both sensors connected to the bypass switch (Tap) fail. Options are fail-open or fail-closed, meaning the line is switched through or is disconnected.
