    Hi,

    MX960
    junos 18.4R3.3

     

    I have a problem with upload policer. We are using ae interface which consists of 4 xe interfaces.

    The clients have 4 times high speed than I set via dynamic-profile but only for upload. For downloading speed is rated correctly.

     

    I have read the article and made changes according to it 
    https://kb.juniper.net/InfoCenter/index?page=content&id=KB31589&cat=VMX&actp=LIST

     

    But the uploading is not rated correct.

     

    Could you help with that

     

    Thanks,

    This is a good solution for clients who use high speed with multisessions.

    But for speeds like 20 - 30 - 50Mbits clients will see half his speed when testing on speedtest.net

     

    Maybe some other solution?
    Thanks

    I have set "targeted-distribution;"

    interfaces {
        demux0 {
            unit "$junos-interface-unit" {
                demux-options {
                    underlying-interface "$junos-underlying-interface";
                }
                targeted-distribution;
                family inet {
                    demux-source {
                        $junos-subscriber-ip-address;
                    }
                    unnumbered-address lo0.0;
                }
            }
        }
    }

     

      in Dynamic-profile. It resolved the problem with Download speed.

     

    And set for the input filter  "shared-bandwidth-policer;"

     

        policer "$POLICER_IN" {
            filter-specific;
            shared-bandwidth-policer;
            if-exceeding {
                bandwidth-limit "$SPEED_IN";
                burst-size-limit 512k;
            }
            then discard;
        }
