VDSL connection not restoring after interuption

  • 1.  VDSL connection not restoring after interuption

    Posted 12-26-2022 05:33
    Good day,

    I use a SRX320 with a VDSL2 mini-pim (like https://www.juniper.net/documentation/us/en/hardware/srx300-srx550-hm/topics/topic-map/mpim-1-port-vdsl2-r-overview.html) and everything works fine. my interface configuration (including  the useless credentials)
    pt-1/0/0 {
        vlan-tagging;
        mtu 1500;
        vdsl-options {
            vdsl-profile auto;
        }
        unit 0 {
            encapsulation ppp-over-ether;
            vlan-id 6;
        }
    }
    pp0 {
        unit 0 {
            ppp-options {
                pap {
                    local-name "fake@freedom.nl";
                    local-password "$9$oNJjH.P5F69mP"; ## SECRET-DATA
                    passive;
                }
            }
            pppoe-options {
                underlying-interface pt-1/0/0.0;
                client;
            }
            family inet {
                negotiate-address;
            }
        }
    }
    ​

    A few times a year (i guess after a minor outage) the connection goes down.
    The sync ligt keeps on. and the TX/RX ligt stays off.
    The simple solution is disconnecting the phone cable for a few seconds. after this the the connection restores and life is good again.

    However it would be better if the SRX can solve this automatic.
