Re: Forgot Password

Hello, I recently purchased a used cisco router model isr4221, and when I want to connect through the console port, it asks me for a username and password.
Of course I don't have this info.

Thank you in advance !

Replacing or Recovering a Lost Password

You need to interrupt boot and then

From ROMMON,
1. confreg 0x2142
2. Reboot the router
3. Change the password
4. config-registry 0x2102
5. save the config
6. reboot the router

On the other hand, do you know how to download the IOS software because I do not have a service contract? Thank you

Find the complete filename of the file you want and try web searching.
