saving my config file on flash or nvram and using it when booting up

[pedro juan roig roig]

Hi,

I have 2 questions about it:

1.-  I can't save a customized config file (let's name it my-config) onto nvram. I mean, I try to execute the command: 
"copy running-config nvram:my-config"
and it prompts %Error copying nvram:my-config (Invalid argument)
Is it a way to do this?

2.-  Which command allows you to load a config file different from the nvram:startup-config, as another file stored on the nvram or on the flash memory?
I have been doing some research myself and I have found the command "boot host", but I can't make it work neither from nvram nor from flash.

Is there any way to get it?

Kind Regards,

[Abzal]

Hi,

1. Startup-config is stored on NVRAM after device boots up. So there is already startup-config that's you cannot to replace with another file. Unless there is another value in CONFIG_FILE variable. If I'm not wrong.

2. To change startup-config to other file:

boot config flash:my-config

Hope it will help.

Hi Abzal,

I have been doing some research and the command  "boot config" is only available on the c7200 platform.

The problem is that I would like to change the config file when booting up  on a c2600 platform.

So I would like to know if there is any option to get this with a config file different from startup-config, stored either on nvram or on flash?

Kind Regards,

Running config is stored in NVRAM is it not, to save different config files try;

#Copy run flash:config-file-name

Yes its correct to use;

#Boot config flash:config-file-name

You can load a config into the current running config, but this does merge the two together so I would advise against it.

#Copy flash:config-file-name run

I believe there is an override option, use the ? help.

Sam.

Hi Sam,

You are right about the "boot config" file, but this command is only allowed on the c7200 platform routers.

But I am working on the c1800 and c2600 platforms, so this command does not apply.

So far I know it is possible to store another config file (let's call it my-config-file) on flash.

And now I would like to use this file as a config-file when booting up.

Do you know some way to do this?

Kind Regards,

Hi Pedro,

It should work on other platoforms too. This command is introduced on 11.0

http://www.cisco.com/en/US/docs/ios/12_2/configfun/command/reference/frf007.html#wp1027545

Here is a capture from 1800 router

1800-6#sh ver | inc bytes|.bin

System image file is "flash:c1841c-advipservicesk9-mz.150-1.M5.bin"

Cisco CISCO1841C/K9 (revision 7.0) with 237568K/24576K bytes of memory.

191K bytes of NVRAM.

126000K bytes of ATA CompactFlash (Read/Write)

1800-6(config)#boot config ?

  flash:  URL of the config file

  nvram:  URL of the config file

Thanks

Raju

Hi Raju,

Thanks for this info. I see you are working with  a 15.0 series  IOS. The thing is I don't have access to a c1800 now but I know the IOS I work with on the c1800 platform is a 12.4 series, so I will check out if the command "boot config" is available in that particular IOS.

As per the other platforms, I have tried some of them, such as c2600, c2691 and c3700, and this command is not implemented, as you can see on the following example (valid for those 3 platforms):

R1(config)#boot ?

    bootstrap    Bootstrap image file

    host             Router-specific config file   

    network       Network-wide config file

    system        System image file

Therefore, I would like to know if there is an alternative way to set the config file, particularily on platform c2600.

Kind Regards,

Hi,
If it didn't work for you then I can only suggest you just copy config to nvram to replace startup config.

copy startup flash:backup.cfg
copy flash:myconfig nvram:startup-config

Hope it will help.

Hi Abzal,

That might be a solution, but in order to implement my original idea of loading a config file different from startup-config, is there any other option from the command boot config, such as changing some ROM variable to force loading that particular config file?

Kind Regards,

This is old but the command should be  boot system  flash:...
