Reset CISCO Configuration to factory default


Last Saturday I received a call from UCLM saying that they were not able to connect to the internet. I knew that it's our router here in UC-Main campus that was having a problem. Since last week I keep on getting error on it's NVRAM.

Resetting the configuration of our router is the only option to do it. I stayed until 8:00 in the evening just to reconfigure the router, I've waited that the classes in our satellite campuses will be finished because they were having an online exam on CISCO. So at 7:10 I've reconfigured the router, here are the steps in doing it:

1. Reboot the router, while the router loading Press Control+Break
2. then a prompt >, key in o/r 0x2142
3. then a prompt >, type i (this will tell your cisco to ignore its start-up configuration file from
now on and reboot)
4. after reboot , it will ask you, if you want to configure the router, press no.
5. then a prompt >
6. >enable
7. #erase startup-config
8. #configure terminal
9. #config-register 0x2102
10. #exit
11. #reload

my staying late paid off, the router is now functioning properly.
