5.2 Operating mode configuration
When selecting the operating mode (switches 2 & 3), the configuration is as follows:
• Breakout: Each Ethernet packet transmitted via the network line is mirrored separately in
this mode while maintaining data integrity in the TAP. The send and receive directions are
output separately on the two monitoring ports so that the network traffic can be analysed per
data direction in this case. Another great advantage of the Breakout mode is the visibility of
the network traffic even with a fully loaded network connection. In this mode, the set network
speed is transferred to the monitoring ports.
For example, if the TAP is configured for 100Base-FX, then both monitoring ports will also
communicate on 100Base-FX. Switch value 00
• Aggregation: In this mode, the data streams are bundled and output aggregated on both of
the monitoring ports. This allows you to evaluate the network data of a full duplex line simul-
taneously with a single network interface on your analyzer. Due to the aggregation in hard-
ware (FPGA), faulty packet sequences during recording are a thing of the past in this mode.
For example, you can analyse the entire data traffic aggregated in 100Base-Tx lines without
loss.
The monitoring ports will boot the link with 100Base-FX, 100Base-TX, 1000Base-T, LX, SX or
ZX depending on which speed or speed combination (see section 5.3) is selected for the aggre-
gation mode. Switch value 01
• Regeneration: Regeneration is used to capture 100% full duplex traffic that can be sent to
multiple monitoring devices (up to 3 in this case) for analysis of your network. In this mode, the
network speed settings are synchronised as in Breakout mode and the setting on the DIP switch
is applied to all ports. Switch value 10
5.1 Link Loss Detection (LLD)
Link Loss Detection is a function that checks whether the link has failed on either Network port A or Net-
work port B. If the link has failed on Network port A when LLD is activated, the TAP also shuts down the link
on Network port B, and vice versa.
When the LLD function is selected (switch 1), the configuration is as follows:
• Activate LLD: Switch value 1• Deactivate LLD: Switch value 0
5.3 Speed configuration
In Breakout and Regeneration mode monitoring speed must be the same as networking port speed. In
100Mbit Breakout mode all SFP-s should support either 100Base-T or 100Base-FX, mixing those SFPs is
also supported. In Aggregation mode with 100Mbit passthrough it´s possible to have monitoring in either
100Mbit or 1000Mbit mode. Where in 100Mbit mode there is no packet loss even with 100% speed utilization
on networking ports.
