== Use case: Multiple uplinks in-line or tapped == | |||
If you have the Allegro in-line for multiple separate links, please configure each virtual link group with the 2 interfaces of link. | |||

== Use case: link aggrgation ( LACP,... ) == | |||
The Allegro can also analyse links multiple links that are aggregated to a big network trunk with LACP or similar. In this case, you can mirror the whole trunk, tap it or even install the Allegro in-line. As all packets belong to one link, you do not need to set up a virtual link group. If you connect other links to the Allegro, please set up a link group with all interfaces for this trunk at the Allegro. | |||
== Use Case: Packet broker aggregation == | |||
You can use a packet broker to aggregate many links and forward the traffic on one or multiple interfaces to the Allegro. By this method, you can monitor many low-volume links to one interface, like 64x 1G to 1x 10G or 40G. | |||
To distinguish the links please configure the packet broker to add a separate VLAN label per link. Then configure this VLAN on the Allegro as a Virtual Link Group. | |||
