 === Where can I configure the '''In-Line Mode''' ===
-The '''In-Line Mode''' can be configured at '''Settings''' -> '''Global Settings''' -> '''Packet processing mode'''. The Interfaces can be configured to '''Bridge Mode''' or '''Sink Mode'''. The '''Bridge Mode''' will enable the packet forwarding to the pair ethernet port.

+=== Devices with port extension cards ===
+All Allegros with network card extension slots support the '''In-Line Mode''' by default. All extension cards have either '''2''' or '''4''' network ports. Each card forms '''1''' or '''2''' brides. On extension cards with '''4''' ports, the two left and the two right port as the bride pair.

-{|
+The bypass cards for the Allegro Network Multimeter deliver a failover when the software bypass is not active. The bypass will be enabled when the bridge mode is active when the Allegro Firmware is not running due power off, firmware upgrade process or any kind of failure.

 === Link Setup ===
-The Allegro negotiates every port of a bridge pair independently. This can lead to a link speed mismatch. As an example, an installation between a  Gigabit switch and a 100 MBit/s VoIP telephone will lead by default to a speed mismatch. The Allegro will show a warning

 === Forwarding ===
-The traffic forwarding is done in software.
+The traffic forwarding is done in software. This implies a delay and jitter. The average delay and jitter is below 1 microsecond and does not have ameasurable impact on most networks. The worst case jitter is below 50 microseconds. You can check your average and worst cast jitter at '''System Info''' → '''Info''' → '''Load'''.
