Capture Setup
Trigger Setup
This screen allows you to set up and execute capture of transmitted frames.

will be captured. The available options are: Whole frame, Top 64 Byte,
Top 128 Byte.
Buffer handling
Use the Buffer handling drop-down menu to choose either Stop when full
or Overwrite.

Capture transmitted frames
Select the check box if capturing the transmitted frames.
Clear the check box to capture the incoming frames.
During the 10 Gbit/s rate state, transmitted streams the traffic generator sends
can't be captured.
Transmitted protocol frames can be captured. 'Protocol frames' are the frames
which used for information such as ARP, SyncE, IEEE1588v2, OAM.
This is the same for 10GbE over OTN (OTU2e - 10GbE mapping).
