With the Allegro Network Multimeter | With the Allegro Network Multimeter packet ring buffer, it is possible to extract traffic from the past as a pcap file. The packet ring buffer is stored on the internal storage device of an Allegro Network Multimeter (if your model is equipped with one), or on an externally attached USB storage device. A fast USB3.x capable SSD is recommended. A USB thumb drive can also be used, but some burst packets may be dropped if the thumb drive write speed is too slow. | ||
