MX960/MPC10 wont stat input/output interface rate

    Posted 06-30-2022 19:25
    Hi Folks!

    I need a hand with a weird problem, we have an mx960 with an MPC10, and without reason the interfaces of the PIC 0 stop sensing/record the input and output bw rate, but the traffic still passing without problems, the ports are UP but if I check the interface Input rate and Output rate this counters never changes, the interfaces are part of different lags (each one) and in consequence the input and output rate of the lag is freeze too.

    There is any way to restart the traffic stats collecting without restart the whole fpc?

    For example:
    > show interfaces et-9/0/1 | match rate
    Input rate : 42733206120 bps (3692069 pps)
    Output rate : 743274544 bps (1148363 pps)
    FEC Corrected Errors Rate 0
    FEC Uncorrected Errors Rate 0
    
    {master}
    > show interfaces et-9/0/1 | match rate
    Input rate : 42733206120 bps (3692069 pps)
    Output rate : 743274544 bps (1148363 pps)
    FEC Corrected Errors Rate 0
    FEC Uncorrected Errors Rate 0

    > show interfaces et-9/0/1 | match rate
    Input rate : 42733206120 bps (3692069 pps)
    Output rate : 743274544 bps (1148363 pps)

    Checking the same info at the lag interface (which this physical port is part of), the result its the same:

    > show interfaces ae19 | match rate
    Input rate : 42733206120 bps (3692069 pps)
    Output rate : 743274544 bps (1148363 pps)

    The interfaces config dont have any "special":

    > show configuration interfaces et-9/0/1 | display set
    set interfaces et-9/0/1 gigether-options 802.3ad ae19

    show configuration interfaces ae19 | display set
     set interfaces ae19 aggregated-ether-options link-speed 100g

    set interfaces ae19 aggregated-ether-options lacp active
    set interfaces ae19 unit 0 family inet filter input flow
    set interfaces ae19 unit 0 family inet address x.x.x.x/31
    set interfaces ae19 unit 0 family inet6 filter input flow_v6
    set interfaces ae19 unit 0 family inet6 address x:x:x:x:x:x/127
