fxp0 interface admin down but physically up // can't enable the interface

  • 1.  fxp0 interface admin down but physically up // can't enable the interface

    Posted 14 days ago
    Hello,

    I'm trying to configure a MX104 router at work for a lab.

    We resetted the device and are trying to set a new configuration.

    To have remote access to the device we want to set the management interface, through the fxp0 interface. We connected a RJ45 cable from the fxp0 to a switch that gives us a management access to every device in the lab.

    The interface is "up up" on the switch, and when we disconnect the cable from the fxp0 of the MX104, the interface on the switch turns "down down (not connect)", so that's not a cabling issue.

    On the MX104, the fxp0 is always 'admin down' and I didn't manage to enable it so that it would have turned to "up up", with any common cli commands (delete interface fxp0 disable...etc // the interface configuration doesn't show basically any disabling state...)


    Could you please provide some help?


    Here are some informations on the device:

    Model: mx104
    Junos: 13.3R1.8

    Here are the status of the interfaces (I can't enable any of them...):

    >show interfaces terse
    Interface Admin Link Proto Local Remote
    dsc down up
    em0 down up

    Hello,

    I found the solution: I made a
    restart chassis-control gracefully 
    And now everything is ok!

    Enjoy
