Remote capture—The command setting to enable a remote capture can be saved to persistent
storage. It can be synchronized to the standby supervisor module and a stateless restart can be
issued, if required.
The options within Step 2 may be performed in any order.
Press Ctrl-c to stop a capture. Otherwise, the capture stops automatically after capturing 100
frames. You can change this default using the fcanalyzer local limit-captured-frames number
command.
The final file name is the capture file called either SampleFile_00000_dateandtime or
SampleFile_00001_dateandtime.
For example, "SampleFile_00000_20021110223833" or
"SampleFile_00001_20021110243833".
The maximum size of a file that can be written to is 10 MB.
Purpose
Enters configuration mode.
Begins capturing the frames locally
(supervisor module).

brief format.
Displays the filtered frames.
Limits the size of the frame capture
to the first 64 bytes. The allowed
range is 64 to 65536 bytes.
Limits the number of frames
captured to 10. The allowed range
is 0 to 2147483647 frames and the
default is 100 frames. Use 0 if you
do not want to limit the number of
captured frames.
Saves the captured frames to a
specified file (sample) in the

Optionally, you can save
