Follow the guide on how to Reset a Cisco 3650 Catalyst Switch. This is useful when you want to remove an undesirable configuration that is present in the switch. If you have configured a switch and the configuration has become very complex or if you want to move a switch from one network to another. You can reset the switch to factory defaults and configure it as a new switch. Please see how to Update Cisco ASA software, Fast user switching: How to create a desktop shortcut in Windows 10 to switch User Accounts, and how to configure a console port password on Cisco Router.
What to do before resetting your Cisco Appliance?
Please ensure that all the images, configurations etc are backed up before performing the Factory Reset operation.
- Ensure that the device is not in the stacking mode as Factory Reset is supported only in the standalone mode.
- Ensure that there is an uninterrupted power supply when the process is in progress.
- Ensure that you take a backup of the current image before you begin the Factory Reset process.
- Ensure that neither In-Service Software Upgrade (ISSU) nor In-Service Software Downgrade (ISSD) is in progress before starting the Factory Reset process.

Method 1: Perform Factory Reset
From the privileged EXEC mode, run the command below.
factory-reset all
This erases all the content from the NVRAM, all the Cisco IOS images, including the current boot image, boot variables, startup and running configuration data, and user data.
When the Factory Reset process completes. The device reboots and stops at ROMMON mode.
Method 2: Reset a Cisco 3650 Catalyst Switch
If you wish to restore the Catalyst switch configuration to the original default factory settings, follow the steps below.
A: First, you need to power down the switch. Once the switch is powered off, hold down the mode button, and power the switch on. The switch will boot up and you should see the switch prompt as shown below.
Note: This interrupts the boot process before the Flash file system can initialize, and after a short while (continue holding the “mode” button) you will see the following prompt:
Before proceeding to perform this step, ensure these files are present and therefore delete them
switch: dir flash: Directory of flash:/ 2 -rwx 976 vlan.dat 3 -rwx 386 system_env_vars 4 -rwx 5 private-config.text 6 -rwx 1554 config.text
B: Initialize the flash file system with the command:
switch:flash_init
Next, check out the contents of flash and locate config.text and vlan.dat (if it exists).
C: Delete the config.text file from the flash directory: switch: del flash:config.text
D: Delete the vlan.dat file from the flash directory or have them renamed so you can restore them in the future if need be.
switch: del flash:vlan.dat
E: Reboot the switch and you’re done:
switch: boot
Method 3: Using the Write Erase
Alternatively, you can reset a Cisco router or switch to its factory default configuration by using the “write erase” command followed by the “reload” command. This will delete the startup-config and running-config files and reset the device to its default configuration.
