Power outage, and recovery from it.

I have a hopefully simple question. I have a cisco 806 router for our small company. And I have a worry about losing my configuration if a power outage comes along. I need to know if, and how, it is possible to "flash" or load the entire configuration from a previously saved telnet session, like a show config command dumped into a text file. Or is there any other way. I thought of Cisco ConfigMaker, but it doesnt support the 806. Any help is VERY appreciated, as even tonight, i thought i'd have to make an early trip to the office to re configure my router due to a power-knocking wind storm

Re: Power outage, and recovery from it.


Are you saving the config changes? Typically, running configuration is lost when a router is powered off without saving the config.

Here's the URL on saving config changes from Cisco 806 router config guide.

I do not have access to Cisco 806 router and have never worked on Cisco 806 router. So cant say for sure but "copy" command is what I would be looking for.

This output is from a different router but give it a try.

Router# >copy ?

/erase Erase destination file system.

bootflash: Copy from bootflash: file system

ftp: Copy from ftp: file system

microcode: Copy from microcode: file system

null: Copy from null: file system

nvram: Copy from nvram: file system

rcp: Copy from rcp: file system

running-config Copy from current system configuration

startup-config Copy from startup configuration

system: Copy from system: file system

tftp: Copy from tftp: file system


URL to Cisco 806 Router Software Configuration Guide in case you do not have the documentation:

Re: Power outage, and recovery from it.

Awesome, thanks for the help. And one more question. What do you mean about saving config? If i save my config after i change somthing, everytime, it wont loose it if I have a power outage?

Thanks for your help Nash

Re: Power outage, and recovery from it.

Yes, all the changes made to the configs are lost if they are not saved and power to the router is turned off.

Its like typing a document in say Microsoft Word and not saving the document before powering off the PC.
