If the network interface’s Status column is a red “down” arrow, its administrative status is currently “down” and it will not receive or emit packets, even if you otherwise configure it. To bring up the network interface, edit the Administrative status setting. This Status column is not the detected physical link status; it is the administrative status that indicates whether you permit network interface to receive and/or transmit packets. For example, if the cable is physically unplugged, diagnose netlink interface list port1 may indicate that the link is down, even though you have administratively enabled it by Administrative status. |
