I have a Cisco 2501 that will not retain the config in the NVRAM.   I have made sure that i am copying it properly to the NVRAM.  When I shut the router down and power back up the configuration is gone.  Is there a battery or something I can check?

thanks,

jon

When it comes back up, not the config register setting 0x2101 or something like that.
Next, see if there is a difference between "show run" and "sho start"
The router may just be set to ignore the nvram when it boots up.

it is Ox2102 for normal boot
and you need to use the show version command to see that. It is listed at the bottom on the output for sh ver.
If it is not 2102 then you need to use the config-reg to change it.
