Revert to a previous configuration Cat3850

[pdenableetoavit19698]

Hi there,

is there a way if having some issues since some config changes (without knowing exactly what was changed), to reboot the SW with the previous working configuration?

If so how do you do it?

Thank you!

Hello @pdenableetoavit19698,

since a copy running-config startup-config command is done, reboot is not the solution.

Check the startup-config with #show startup-config command and look if changes are made. If not, reboot without saving.

Also, do you have a server where you save your configuration ? You perhaps have got a former configuration that you could re inject in your CAT3850.

Switch loads saved startup-config text file from flash.  you could rename "start-up config" file (edit file name to something else) or delete it so then switch cannot find it during load process; then switch should load its default factory configuration during booing up.

U can compare running and start-up configs to see changes. Use show startup-config command and copy text to notepad; then use show running-config command and copy text to new notepad in order to compare it.
