راههای بازیابی پسورد وقتی no service password-recovery فعال است :
##روترهایی که چیپ (nonvolatile RAM (NVRAM دارند میتوان آنرا برداشت و تنظیمات را من جمله no service password-recovery از بین برد.
##بعضی روتر ها از یک (electrically erasable programmable read-only memory (EEPROM برای نگهداری تنظیمات استفاده میکنند که با برداشتن آن تنظیمات از بین نمیرود مانند سری 1700 , 2600 و 3620.
##یکی از روش ها بوت کردن روتر با پورت کنسول و فشار دادن CTRL-BREAK در 5تا 10 ثانبه زمانی که CISCO IOS در حال decompressing یا وقتی که "Image text-base:... " بنر شروع میشود.در این حالت به شما پیغام برگشت به تنظیمات کارخانه میدهد(erase start-up configuration).
