copy running-config startup-config not saving

[ajeni0001]

hi,

 we bought a  cisco 3945 router recently. i did the initial configuration and saving is using copy running-config startup-config. but it is not getting saved properly. whenever i restart the router, it asks for initial configuration. that is every time i have to give IP address and other configuration after i switch off and on the router.

kindly help me

thanks and regards

There is a configuration-register that controls if the startup-config is loaded on startup or not. It's likely that the config is saved but not loadad. If this is the case, you can see your config with "show startup-config".

You can see the actual value of the config-register with "show version". You set the default-value with

config-register 0x2102

More on this topic is found in the config-guides:

I also have this problem except mine is on a 3650. How do I go about changing this?

Thanks,
