  • 1.  Question ex9253 setting chassis chassis port speed to 40g

    Posted 15 days ago

    Its been a while since I equipped and configured ports on a couple of these.   I need to add a couple of non-channelized 40GE qsfps
    and although I have this set,   with 1 of these:  QSFP+40GE-LX4,  the h/w does not show up.
    set chassis fpc 1 pic 0 port 4 speed 40g

    I know on some platforms an FPC reboot is required with certain ports / port group changes. 

    Its not simple to reboot the FPC  due to other services.  When I say reboot, can anyone chime in on preferred solution ?

    request chassis fpc slot 1 offline ; then online to reboot card. 

    Since its only this PIC,  might this work as well  :request chassis pic pic-slot 0 fpc-slot 1 offline

    I found my own answer for this.   In my case the chassis posts this alarm that I noticed from a log message.
    That led me to this general KB
