  • 1.  SRX345 long ping times

    Posted 12-24-2022 08:02

    Hello, there is a srx345 with the following config:

    set class-of-service forwarding-classes queue 2 icmp_prio
    set class-of-service forwarding-classes queue 2 priority low
    set class-of-service scheduler-maps CoS forwarding-class icmp_prio scheduler icmp
    set class-of-service schedulers icmp transmit-rate percent 25
    set class-of-service schedulers icmp buffer-size percent 25
    set class-of-service schedulers icmp priority low


    set firewall filter ICMP_PRIO term 1 from protocol icmp
    set firewall filter ICMP_PRIO term 1 then forwarding-class icmp_prio
    set firewall filter ICMP_PRIO term 1 then accept
    set firewall filter ICMP_PRIO term 2 then accept

    the ping works horrible, thats why CoS was implemented in the first place, slight improvement after COS:

    Laptop@192-168-0-82 ~ % ping 65.199.16.62
