Configuration/DIP Switch Settings
DIP switches on the back of the TAP can be used to configure speeds, modes, and link
failure propagation.
Definitions
LFP
(Link Failure Propagation): Allows link state to be mirrored to the adjacent live
network interfaces.
Duplex:
The AUTO setting allows auto-negotiate to advertise full duplex operation.
The FULL setting forces full duplex operation without using auto-negotiate.
SYNC
(Synchronization): Allows auto-negotiate to choose the link speed and synchro-
nizes the link speed of the network ports.

* Synchronization Mode provides a plug-n-play zero configuration design. Synchronization Mode will determine the highest
supported speed of network ports [A] and [B]. Ports [A] and [B] will link, then advertise and connect at the highest supported
common network speed.
Link Failure Propagation (LFP) :
•
LFP is used mostly for High Availability (HA) designed networks.
•
LFP applies to Network ports only.
•
When enabled, LFP can sense a network failure and reflect the failure to the adjacent port of the live network allowing the
network’s failover mechanism to switch over to the secondary network path.
•
LFP ensures an instant switch to the secondary link to maintain 100% uptime.
Configuration/DIP Switch Example
•
This TAP operates in
Aggregation mode,
which combines traffic from both port A
and port B and transmits an aggregated
copy from the USB monitor port.
