It's documented:
output_port: optional weak reference to Port
Output port for selected packets, if nonempty.
Specifying a port for mirror output reserves that port exclu-
sively for mirroring. No frames other than those selected for
mirroring via this column will be forwarded to the port, and any
frames received on the port will be discarded.
The output port may be any kind of port supported by Open
vSwitch. It may be, for example, a physical port (sometimes
called SPAN) or a GRE tunnel.
