Cisco 887 VDSL ΟΤΕ

[edomeneas]

Καλησπέρα σας,

Έχω ένα cisco router 887 και προσπαθώ να το κάνω να δουλέψει αλλά χωρίς αποτέλεσμα.
Το configuration του είναι το παρακάτω.

Έχει κανείς καμιά ιδέα για το τι μπορεί να φταίει;

Τι πρόβλημα έχεις ακριβώς ?

Γενικά, νομίζω ότι σου λείπει ένα default route ( ip route 0.0.0.0 0.0.0.0 Dialer0 ) . Επίσης, το nat statement σου κάνει reference το Dialer1 που δεν υπάρχει. Σβήσε το και βάλε Dialer0 στη θέση του.

[edomeneas]

Συνδέεται, παίρνει IP και μετά αμέσως κάνει disconnect.
Συγκεκριμένα αναφέρει missed too many keepalives.

Μήπως θέλει VPDN;

[SfH]

Όχι. Ενδιαφέρον. Υπάρχει ένα σχετικό bug που επηρεάζει 15.1(3)T , 15.1(3)T1 , αλλά προκαλεί τη συμπεριφορά που ανάφερες σποραδικά, όχι μόνιμα. Αναφέρει σα workaround reload.

Άνοιξε debug ppp negotiation , debug ppp authentication , debug ppp error , debug pppoe events και debug pppoe errors και γράψε το output. Επίσης γράψε το output από show interface atm0, show interface ethernet0 και sh controllers vdsl 0 .

Λογικά δεν έχει άμεση σχέση με το πρόβλημα που αναφέρεις, αλλά τώρα πρόσεξα τη λίστα που έχεις για το NAT. Καλό είναι να βγάλεις το permit ip any any και να βάλεις το εσωτερικό σου δίκτυο ( π.χ. permit ip 10.10.10.0 0.0.0.255 ).

Η σύνδεση είναι VDSL over PSTN.
Όπως λένε οι τεχνικοί του ΟΤΕ η γραμμή είναι VOB.
Επίσης παίρνει static IP.
Με ένα Speedport Entry 2i που δοκίμασα, δουλεύει κανονικά.
Δεν ξέρω αν αυτά βοηθάνε σε κάτι, αλλά δεν μπορώ να καταλάβω τι πάει στραβά!!

[SfH]

Καλησπέρα,

Δείχνει χάνει το συγχρονισμό. Θα δοκίμαζα διαφορετικές εκδόσεις ios ή/και vdsl firmware.

Πιθανώς θα είχε νόημα αν μπορούσες να τρέξεις το sh controllers vdsl 0 ενώ έχει συγχρονίσει για να δούμε στατιστικά.

[edomeneas]

Από τον ΟΤΕ μου είπαν ότι πρέπει να υποστηρίζει vectoring για να παίξει.
Λογικά το 887 το υποστηρίζει, σωστά;
Να βάλω το τελευταίο IOS/VDSL firmware;

Ακολουθεί και το sh controllers vdsl 0 όταν είναι συγχρονισμένο.

Επίσημα δεν αναφέρεται κάπου ( και δε νομίζω να δούμε κάποια αλλαγή στο datasheet ). Είναι πιθανό όμως να το έχουν προσθέσει για κάποιον μεγάλο πελάτη τους, πιθανώς να υπάρχει κρυμμένο σε release notes για το vdsl firmware. Δε χάνεις τίποτα να δοκιμάσεις την 15.6.3M4 με/χωρίς το VA_A_39m_B_38u_24o .

[edomeneas]

Αυτές είναι οι τελευταίες εκδόσεις;
Κάνουν και για 887 και για 886;
Επειδή δεν έχω κάνει ξανά αναβάθμιση, πρέπει κάτι να προσέξω;
Υπάρχει κάποιος οδηγός μήπως;

[SfH]

Είναι σχετικά καινούριες. Μπορείς να δεις σχετικό οδηγό εδώ ( για το router που έχεις, θα το βάλεις στη flash ). Για το firwmare, μπορείς να δεις τα release notes εδώ .

[edomeneas]

Κάνουν και για 887 και 886, σωστά;
Επίσης πρώτα πρέπει να βάλω το IOS;
Γίνεται να κάνω την διαδικασία από στικάκι;

[SfH]

Το ios είναι κοινό, το modem firmware λογικά είναι άλλο. Αν είναι λειτουργικό το usb ( δεν είναι σε όλα τα μοντέλα για αυτό το σκοπό ) τότε ναι, μπορείς να κάνεις copy από usbflash στη flash .

[edomeneas]

Ψάχνοντας το site της Cisco για IOS και firmware έχει διάφορες επιλογές για 887 router.
π.χ. 887VA ή 887VA M
Πως θα καταλάβω από ποια πρέπει να κατεβάσω;
Το δικό μου είναι το 887VA-K9.

[SfH]

show inventory . Αν δεν ξέρεις τι έχεις, πιθανότατα 887va απλός είναι. Λογικά όλοι οι παρεμφερείς έχουν και ίδιο ios. Ότι κι αν περάσεις, καλό θα είναι να διαβάσεις και τα release notes.
