When i try to login my cisco 1751V
router. Unfortunately, I didn’t receive the credentials to log on to the
router. As a ‘note to self’: here comes the password recovery procedure for a
1751V.
- Turn the power on.
- Press the ‘break’ key within 60 seconds (in putty, I needed to use CTRL-Break). You should get to the rommon prompt:
rommon 1 >
|
- Change the configuration register so the router will ignore the existing config (this 0x setting can vary):
rommon 1 > confreg 0x142
|
- Next, reset the router:
rommon 2 > reset
|
- Once the router has restarted, it will ask you if you would like to enter the initial configuration dialog. There you go. You now have two options:
- Copy the startup-config to running-config and change the password for any username that exists in the startup-config.
- Just start from scratch.
Since I just wanted to start from
scratch, I was ready to go from there.
I am really impressed your written a blog. Hope we are eagerly waiting for such post from your side. HATS OFF for the valuable information shared!
