Factory default config for cisco 871w router

geraldohernandez · ‎01-26-2008

I blew away the factory config that came with my 871w router. now i can not use my sdm disk because it is looking for the 10.10.10.1 ip scheme. can anyone please provide this config so i can start using my router?

For the fresh configuration of the router follow the below steps:

Sample procedure is as follows:

Router#config t

Router(config)#config-reg 0x2142

Router(config)#end

Router#show version (check the last line of the output)

Router#reload

When the router reloads, please type this command:

Router#write memory

Router#config t

Router(config)#config-reg 0x2102

Router(config)#end

Router#reload

At this moment, your router is at Factory default and ready to set any configuration.

Or another way is:

Router#write erase

or

Router#erase nvram:

On the 8xx, two more ways:

copy flash:c871-default-sdm.cfg startup-config

reload

(I made up the exact flash filename, do dir and you will see it)

or press the reset button just after turning on.
