Unanswered Question

I have a cisco 837 that I have a saved config from. The 837 is now faulty and I need to run up another and restore the config (via tftp on my laptop) and send it out to replace.

1.) I have another 837 that I need to reset as I don't know the password.

2.) What commands do I need to use to restore the config from my laptop?

I can copy and paste the whole lot in one go? Or in stages? Will it just overwrite what's already on the config?

Thought maybe I could just tftp it back?

If you want to tftp it use:

copy tftp: startup-config

But i always use to do copy and paste in stages, in order to review what i am copying.

Start cisco from console and press Break 1 time per 2 sec.

When cisco come to rommon type confreg 0x2142

Like this:

rommon 1 confreg 0x2142

rommon 2 reset

After reboot router, ignor save configuration

Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure

Type enable at the Router> prompt.

Type copy startup-config running-config

Type show running-config (u see conig)


conf t

username xxxxxx privilege 15 password xxxxxxx


conf t

write memory

After Configuration register is 0x2102

Great, then copy and paste the backup I have? Or better to use tftp?

Will the tftp put on exactly the same config as the backup? So I don't need to do anything else?
