Re: cannot save configuration changes on catalyst 3548

jthomas · ‎07-28-2006

i have an old switch that worked when last on network. powered on normally, but when i attempt to make configuration changes (copy running config startup config), it fails. where can i find information on working with file systems Version 12.0(5.3)WC(1), MAINTENANCE INTERIM SOFTWARE

Be sure you are in configuration mode to make the configuration changes and in "enable" mode to save them.

router> <----- read only mode

router> enable

password: *******

router# <-------- enable mode is where you can "copy run start or "write mem"

router# configure terminal <--- go into config mode from enable mode.

You need to be in enable mode to do much of the commands, see the following example:

Switch>wr me

^

% Invalid input detected at '^' marker.

Switch>copy run start

^

% Invalid input detected at '^' marker.

Switch>en

Switch#copy run start

Destination filename [startup-config]?

Hello,

in addition to the other posts, what is the exact error message you are receiving ? It is also possible that the configuratio file in your flash has become corrupted. Do a:

3548#dir flash:

You should see a number of files in flash, the file named 'config.txt' holds your configuration. Try and delete that file with the command:

3548#del flash:config.txt

and try to save the running to the startup config again.

Regards,

GNT

Try to "fsck flash:" as suggested.

va-research-3548-06#fsck flash:

If fsck fails, you will no recourse but to replace the switch, it's toast.
