Cisco 878 "priv" command password recovery in Rommon mode

satlandi · ‎06-29-2010

Hi,

There was " Cookie information corrupt" error on cisco 878 and I enter cookie information with cookie command. The priv command password is "0000" when all cookies zero, but I inserted wrong cookies . I want to edit cookie information. The priv command password changed and I can't edit cookie informations.

How can I recovery priv command password in rommon ?

Thanks for help,

Hi friends,

I solved problem. You must add the first five numbers in 16-bit hex in cookies :

Sample :

	00	01
+	00	30
+	85	d7
+	e0	60
+	0a	ff

————————-
= 17167

The password is only four characters, so remove the most significant bit and the password is 7167.
