4.2.3. Capture Features
This tab allows the configuration hardware capture settings. The available settings depend on the IOTA
model. Features can be enabled and disabled by ticking or unticking the related checkboxes.
IOTA 1G / 1G+
Keep CRC32
The CRC32 information (32-bit Frame Check Sequence) located at the end of the packets will be kept in
the capture.
Disable Port A
Frames from port A will not be captured.
Disable Port B
Frames from port B will not be captured.
Transmit CRC Errors
Packets with CRC errors will be included in the capture. These packets are usually filtered out by network
interfaces.
Packet Slicing (128 bytes)
The payload of every captured frame will be dropped, keeping only the header information (the first 128
bytes) up to the application layer.
Synchronized Timestamps
Allows the capture interface's clock to be disciplined with the IOTA's embedded OS clock, thereby avoiding
drift.
