== In-Line | This section describes the In-Line installation of the Allegro Network Multimeter. | ||
== General == | |||
=== What is the '''In-Line''' mode === | |||
The '''In-Line Mode''' allows the Allegro to work as a transparent bridge. Pairs of network ports form a group where all received traffic is forwarded immediately to the other port of the pair. It is the default configuration of the Allegro Network Multimeter that 2 port pairs build a transparent bridge. | |||
=== How should the In-Line mode be used === | |||
The Allegro can be installed between 2 network devices. As an example, the Allegro can be installed between a switch and an access point. | |||
The '''In-Line Mode''' is designed for links where the downtime of a link is '''not''' critical and where a delay and jitter of a few microseconds is acceptable. See [[#Limitations]] for more details. | |||

=== 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 100MBit/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. | |||
