Hi cannot save configuration change in router 3825. When typing this command "copy run star" I got the below error message. Any suggestion? Thank you
% String too long to write to nvram (2120):[OK]

Yes, If you reboot the router without saving the config to NVRAM then all your config will be gone.
Either you can save the config to flash by using the command
copy running-config flash:saved-config
Once your router came back online after reboot then copy the file from flash: to running config by using the command
copy flash0:saved-config running-config
Your config will be loaded successfully. But you can't do it from the remote. You must have console access.

Hi,
This looks to be a known bug (CSCsd45386) in cisco IOS. Kindly check routers IOS version is it 12.2(28)SB, 12.2(31)SB, 12.3(7)XI?
Workaround:
a) You have to disable parser config cache as
Router(config)#no parser config cache interface
Router(config)#end
Router#clear parser cache
b)You can upgrade to latest/sugested IOS.
You can get more about the this bug at below link

Thank you so much for your reply. without the workaround action, if we reboot the router, all changes we made would be gone. Can I say it like that?
