Solved: Cisco 3835 Router Configuration problem

olakunle06 · ‎06-27-2007

Hi there,

I have an issue with a Cisco 3825 router. When I try to save the running config it shows a paticular error. This same error is displayed when I run the SH START command.

Router#sh start

Using 1826 out of 491512 bytes

%Error opening nvram:/startup-config (Unknown error 0)

Pls can you help by telling me the source of the problem.

Thanks

Hi,

Did you upgrade the IOS lately?

What you also can try:

Router#erase /all nvram:

Router#copy running-config startup-config

It might remove the error messages. Note: erase nvram is not sufficient.

I think you are hitting the Bug CSCin98933.

Try upgrading the IOS to 12.4(07a), 12.4(7.20), 12.4(7.20)T

The router I'm working on runs Cisco 12.4(11)T. This version is higher than those you mentioned. Could it be the same bug?

Could be...

If you can get a downtime, i would recommend upgrading it to the latest available train and check

Thanks,

It solved the issue. Apparently, it was an NVRAM problem. Erasing the nvram resolved the problem.

No I didn't upgrade the router. It's a brand new router.
