[j-nsp] UK adsl config

[Nick Ryce]

Finally managed to get it working:-

It was the vci0.38 and encapsulation changed to atm-ppp-llc which is a bit strange but hey ho.

Thanks for all the help guys.

Nick

Gave that a try and still nothing.

Forgot to mention that i have set keepalives as the adsl line is a backup and no traffic is flowing.  Would the interface come up without traffic going through it?

Hey Nick,

AFAIK, the access-profile configuration should work if the client name
matches the service provider BRAS hostname.

Try to use "passive" knob under ppp-options chap & also add local-name
under it.

unit 0 {
    description "ADSL Backup";
    encapsulation atm-ppp-vc-mux;
    vci 38;
    ppp-options {
        chap {
            access-profile adsl-details;
                local-name <> <<---
                passive; <<---
        }

If that doesn't work, wont be a bad idea to try the other way round.

i.e., using "passive" knob under the [ppp-options chap] and also
"local-name <name>" and "default-chap-secret <secret>".


unit 0 {
    description "ADSL Backup";
    encapsulation atm-ppp-vc-mux;
    vci 38;
    ppp-options {
        chap {
            default-chap-secret ""$90BIRhr";## SECRET-DATA
                local-name <>;
                passive <<--



Thanks & Regards,
Tarique A. N.

Hi Guys,

I am having difficulties getting an adsl pim module to work in a j2320
running 9.3R2.8 Enhanced services.

SP is using ppoa whith chap authentication and I have confirmed the adsl
line is working by using a netgear adsl modem.  We are seeing sync but
cannot establish a PPP connection.  Below is my config, any help much
appreciated.

description "ADSL Connection";
mtu 1500;
encapsulation atm-pvc;
atm-options {
    vpi 0;
}
dsl-options {
    operating-mode auto;
}
unit 0 {
    description "ADSL Backup";
    encapsulation atm-ppp-vc-mux;
    vci 38;
    ppp-options {
        chap {
            access-profile adsl-details;
        }
    }
    keepalives interval 10 up-count 1 down-count 3;
    family inet {
        negotiate-address;
    }
}


Adsl-details have a client name anc a chap secret which we have
confirmed is correct.

Nick
