Unplugging a Cisco SF200-48 48-Port 10/100 Smart Switch, will I lose my network configuration?

[carnoldIII]

if I uplug my Cisco SF200-48 48-Port 10/100 Smart Switch will I lose my network configuration?  I am new to this company with no little-to-No turn over, switch passwords were expired I created new passwords, now I am locked out, do not want to reset, I do even know if a backup was ever made, so I just wanted to try a hard reboot of switch by unplugging to see if new passwords I create would take?

This is me again, just simply wanted to find out if I could unplug my cisco switch without losing the current network configuration?

Hello

If you are happy with and have a working “current” running configuration you simply ;

“copy running-config startup-config”

Make sure you hint enter at the appropriate questions.... Then you can “reload”.

For many Cisco switches the way to save the running config is copy run start. But the SF200 switch uses a GUI and not the command line. So the process to save the running config is not copy run start but is to click the Save icon in the GUI.

But the advice offered in several preceding posts is correct that if changes have been made in the configuration but the save function has not been selected then power cycle of the switch will lose those config changes. Perhaps this document has information that might be helpful

Fundamental concept to understand:

Running config – meaning any changes made to the switch's configuration, but not saved to nonvolatile memory. Think of these as 'live' changes.

VERSUS

Startup config – this is the configuration that will persist through a power cycle.

Any configuration change made to the switch while it's running are saved only to the running config. One must specifically perform a duplication of the running config to the startup config in order to 'save' any changes.

Simply unplugging and replugging this switch will not affect the startup configuration.

Ironically, if you failed to perform this duplication process after you updated the expired password, then you're in luck: a power cycle should revert the password/s back to that which had expired.

Since this switch was presumably being properly maintained at some point, it's unlikely that any of the networking configuration itself was not properly saved (i.e. duplicated to the startup config) by your predecessor admin.

Hope this helps.

P.S. if you can recall clicking a red, blinking 'Save' alert at the top of the GUI after you updated the expired password, then that will have duplicated the running config to the startup config and therefore saved the password you set.

Once you changes done you need to COMMIT the config.
