Καλησπερα,

Αντιμετωπίζω ενα πρόβλημα με το ADSL του router μου αλλά δεν είμαι σίγουρος αν είναι το ADSL η το ίδιο το Cisco. Συγκεκριμένα, συγχρωνίζει αλλα δε προχωράει στο ppp negotiation.

Υποψιάζομαι οτι κάτι παίζει με το PPP αλλά δε μπορώ να βρω τι ακριβώς. H Γραμμή παίζει με απλό ADSL modem και συγχρονίζει κανονικά.

Ευχαριστώ

To PCV πως το έχεις ρυθμισμένο, με PPPOE ή PPPOATM;

Δες με show pppoe session ή show pppatm session αντίστοιχα αν έχεις established session.

Αν δεν βλέπεις sessions δες τα αντίστοιχα debugs.

Ποιό είναι το output της sh dsl int atm 0 ;
