non so cosa siano le ultime righe

[samoka]

ho capito:....
sono entrato in conf t.... e ho copiato la configurazione suggerita da NGI,
vorrei sapere come cancellare quello che c'è in conf t
grazie

[samoka]

aiuto non so + che fare

[minnie]

dopo essere entrato in conf t
inserisci no prima di ogni istruzione che vuoi cancellare...

[MaiO]

Come ti hanno già suggerito,

entra nella conf t, impartisci ERASE NVRAM e poi RELOAD.
Tutta la configurazione sarà cancellata.

Prima di fare qualla operazione fai un SHOW VERSION e acertati che il valore Configuration register sia OK (di solito 0x2102
). Per i valori di conf register vedi qua http://www.cisco.com/en/US/products/hw/ ... 493f.shtml

Facci sapere.

Ciao

la cfg la cancelli anche con
