About

The Virtual Link Group allows to group traffic in virtual links on the Allegro Network Multimeter. By default, the Allegro aggregates all traffic on all interfaces and the ingress interface makes no difference for the analytics. The Virtual Link Group allow to split the traffic into separate groups.

If the Allegro Network Multimeter monitors more than one link, it must distinguish each link. If for example one packet is seen on each link, it is NOT a retransmission. If it is seen twice on the same link, it is a retransmission.

Configuration

Please check the wiki manual for detailed description Virtual Link Group functionality.

Please note that each packet will be assigned to the first matching virtual links group. To avoid double accounting of packets, each packet can be only part of ONE link group. If you need to group overlapping groups, please use the IP module#IP Groups

Use case: Multiple uplinks mirroring with multiple mirror ports

If you would like to monitor multiple uplinks of a switch, router or any other network device, you can configure a mirror port for each uplink on your switch.
