Yes, I understand it, I was referring to link events in the previous
comment. However, why not to report compressed vlans for GETLINK by
default if show_details is true, this would be consistent with events monitor.

It seems to be more clear and intuitive from the user's perspective, the
same set of command line options for \monitor' or 'show' commands.
