Mon router mc3800 série a crashé

essaye de mettre le baud rate à 19200 dans Putty puis une fois que tu as accès à la console tu vas changer la valeur du registre de configuration à 0x2102,tu sauvegardes.tu reloades le routeur et puis tu rechanges le baud rate à 9600 sur Putty et tu te reconnectes et ça devrait fonctionner.

Salut,
si tu as retrouvé ton port console à 9600 bit/s en remettant le config-register à 2102, et que tu es en router(boot) c'est que tu n'as pas d'ios ou que l'ios est incorrect, il faut en recharger un par tftp.

Oui cette solution m'aide beaucoup merci :)

J'ai suivi les conseils de mettre les valeur à ses d'origine 0x2102 mais il prend que 0x2142 si je veux aller sur le port 9600 bit/s en remettant le config-register à 2102, la fichage des caractère difficile toujour a comprendre est ce que c'est normal ?

Désolé ça fait beaucoup d'heures que j'écris

Voilà je me demande qui pourra me dir mes error?

Est ce que tu peux accès à distance à mon router merci

Lorsque je fait yes pour 2102 j'ai toujour mauvais caractère sauf si je le laisse à 2142 je suis perdu?

bonjour

le config register permet de demarrer sans utiliser la startup-config.
il fixe aussi la vitesse à 9600.

pour des details , voir ici :
https://www.cisco.com/c/en/us/support/docs/routers/10000-series-routers/50421-config-register-use.html

D'apres le résultat des commandes plus haut , il semble qu'il n'y ait pas d'IOS pour booter.
au prompt router# , en tapant boot puis <enter> , ca donne quoi ?

Non,Je n'est pas lecteur compact flash

Voilà que ça donne ça fonctionne sur la valeur 2102

comme l'a dit brupala , tu as écrasé ta config.
il faut en trouver une sauvegarde
l'ios est , normalement, sur une carte flash memory , dans le routeur.
elle a du dégager
il faut trouver un moyen d'y remettre un IOS .

Je n'arrive pas a trouve l'iOS pour mon router cisco mc3800 série comment choisir parmi la liste que je t envoyais et la processeur de tftp ça marche j attend juste le bon fichier quoi faire d'après vous?

Salut c'est derrick
T'as raison c'est un vieux router mais fonctionne il a besoin de patience et de la volante moi c modèle Mc 3810 série 3800 au début j'ai perdu l'espoir mais après que les valeur sont maintenant a 2102 je continue à travail pour mieux comprendre les fonction de cisco

T'as raison date
