Examples
1. Run ibdump.
--mem-mode <size> when specified, packets are written to file only after
the capture is stopped. It is faster than default mode
(less chance for packet loss), but takes more memory. In
this mode, ibdump stops after <size> bytes are captured
--decap Decapsulate port mirroring headers. Should be used when
capturing RSPAN traffic.
-h, --help Display this help screen.
