How can I debug a PPPoA connection on a ADSL PIM ( SRX240)

How can i debug what is happening or not happenign with an ADSL interface in a SRX240..  I need to set up a PPPoA connection.. The physical layer is coming up, but i don' get any connection.. I'm not sure if i have a chap/pap issue.. The DSL line is good, my trusty old SSG20 works fine with it..

 

Any clues greatly apprecaited.

In operational mode: show interfaces at-1/0/0 extensive.

Look for PAP and CHAP status. If they say 'closed' check the user/pass. Does the username has a @yourisp.com in the end and you have missed this....?

Look for showtime seconds and if they go up then the physical link is synchronized, which oftenly means some credentials error or error in encapsulation.

look for errors in general and post them here.

Try using only PAP or only CHAP, do not configure both.

 

Kindly share your configs also image version.

Try configuring Passive option under ppp-options.

Hi Andrew,

            }
        }
    }
    at-2/0/0 {
        encapsulation atm-pvc;
        atm-options {
            vpi 0;
        }
        dsl-options {
            operating-mode auto;
        }
        unit 0 {
            encapsulation atm-ppp-llc;
            vci 0.50;
            ppp-options {
                pap {
                    access-profile pppoa-client;
                    local-name adsl_username_here;
                    local-password adsl_password_here
                    passive;
                }
            }

                negotiate-address;
            }
        }

}
routing-options {
    static {
        route 0.0.0.0/0 next-hop at-2/0/0.0;
    }
