Given that this is a status flag, presumably the presence of it means the link is down, and the absence of it means the link is up.

One more thing I wanted to ask is: If I connect cable again . So is the same message going with OFPAT_PORT_STATUS with ofp_phy_port with different flag value. Because I checked in openflow.h, there is flag for Down event: OFPPS_LINK_DOWN but for Up event, there is no such flag.

Is it the same as PORT_DOWN event? Thanks in advance.
