The Allegro Network Multimeter does '''NOT''' use the time stamp of the ERSPAN receiver since there is only one real-time source for the Allegro Network Multimeter. | The Allegro Network Multimeter does '''NOT''' use the time stamp of the ERSPAN receiver since there is only one real-time source for the Allegro Network Multimeter. | ||
=== Back-In-Time support === | |||
Please note that the back in time support requires that the storage is fast enough to extract the packets at the configured speed. A replay with factor 1.0 should work as most ring buffer can read with the same speed as they can write data. Please stop or pause the ring buffer in this case to allow high speed reads. Higher factors work very well as long as the capture rate was lower than the replay rate. | |||
If the storage is not fast enough, the replay will slow down to the storage speed. If you use the Back-In-Time mode without any speed limitation, it will be limited by the storage and the interface link speed. | |||
