7.4 Autonomous operating mode, general conditions and
requirements
In the "Autonomous operating mode" of the NANL-B500G-RE device (from
the netANALYZER image version 1.2.0.0) the analyzer device is not
connected to a PC. Data recording is started or stopped via the red REC
button on the device front side. The created PCAP files are stored in a ring
buffer.
"Live dump mode" and "Snapshot mode"
There are two possibilities to operate the netANALYZER in autonomous
operating mode without PC.
· In "Live dump mode" , the unit stores all recorded traffic directly to a
connected USB memory device. The PCAP files created fill the entire
USB memory. When the USB memory is full, the oldest recorded
Ethernet frames are overwritten by newer ones. To use this mode,
simply connect an empty USB memory to the device and press the REC
button. For more information, refer to the section
Full capturing process
(Live-Dump-Mode) [
}
page 49].
·
The "Snapshot mode" is suitable for long-term measurements. The
device saves an Ethernet frame snapshot each time a trigger condition
occurs. The trigger condition was previously defined by a "Snap" trigger
block in the netANALYZER Scope software. For further information see
section
Capturing snapshots (snapshot mode) [ } page 51].
Important:
If the power supply of the NANL-B500G-RE is expected to fail
during capturing, the USB memory device can be used with an ext4
file system to prevent data loss. For further information, see section
Notes for installation and operation [
