Problems with capturing high network loads
When capturing with extremely high network loads on all 4 netANALYZER
ports, the capture stops with the error code 0xC066000C (no intram buffer)
or 0xC0660004 (no DMA channel).
When capturing on 4 Ethernet ports simultaneously, a maximum network
load of approx. 96 % can be monitored. For higher loads a special high-
load capture mode is available. See "High-load capture mode" for details.
The high-load capture mode is set in the netANALYZER Scope software.
Note:
This restriction does not apply when capturing only on 2 Ethernet
ports.
Possible workarounds:
1. Use the hardware filters to filter out specific frames, which are not of
interest.
2. Use the high-load capture mode, available via netANALYZER Scope
software. Using the high-load capture mode would not require a Scope
license. In the high-load capture mode all frames will be cut off at byte
offset 58, in order to reduce the total data amount transferred to the PC.
Cutting of at offset 58 would still allow observing all the Ethernet and IP
header information, but would cut off data payload.
3. Only capture on one TAP, then you can capture 100% load on that TAP
