mi sono appena iscritto al forum e posto subito la mia prima domanda.
sono alle prese con la configurazione di un router Cisco 827 con una
connessione Tiscali Wholesale brandizzata dal mio Isp.
La connessione e' una 1280/256 con 8 ip statici
Il problema e' che spesso la connessione cade e poi si riprende, ma
dopo un tempo variabile da 10 minuti a 12 ore, rimane "imballata" l'interfaccia Virtual-access 1 con uno stato down e non ne vuole sapere. L'unico modo di farla riprendere e' un reload, dato che il semplice shut/no shut della connessione Atm non risolve nulla.
Ora le domande:
Come faccio a verificare se ho problemi di linea ?
Ho attivato alcuni debug ma non sono riuscito a capirne molto, dato
che con Atm ho poca esperienza.
Quello importante credo sia questo:
