  • 1.  CER platform MTU/ Frame size issues

    Posted 11-22-2021 14:22

    We have never played with MTU/Frame size, all left at Default
    which show max-frame-size 1548 port wide.

    But i can't seem to ping across a fiber circuit to another CER (P2P) style /30 on each end
    with higher than a 1470byte frame with the No-Frag reference to the ping.

    How to fix?

    Thanks

    Chris

    On the MLX and CER execute the global command "default-max-frame-size 9216".  Write mem and reboot.  You have to reboot these units for jumbo frames to be enabled.

    Does this affect all my other customers traffic?

    I have thousands of customers ~ just one is complaining of this issue

     

    Thank you

    It will not affect other traffic.
