How to Delete Configuration on Cisco Switch or Router

**Introduction**:
Briefly explain why someone might need to delete the configuration (e.g., resetting a device before reconfiguration or troubleshooting).

*Step 1: Access the Device*
Connect to the device via console cable, SSH, or telnet.
Ensure you have admin privileges.

*Step 2: Enter Privileged EXEC Mode*
Access the privileged EXEC mode by typing `enable` and entering the enable password.

*Step 3: Show Current Configuration (Optional)*
Run the command: `show running-config` to display the current configuration.

*Step 4: Delete the Startup Configuration*
To delete the startup configuration, use the following command:
```
write erase
```
Or:
```
erase startup-config
```

*Step 5: Verify the Configuration is Deleted*
Check by running: `show startup-config` to ensure it's empty.

*Step 6: Reload the Device*
Reload the router or switch to apply the changes using the following command:
```
reload
```

*Step 7: Confirm the Reload*
When prompted to save the configuration, type `no` to discard it.
The device will reboot with no configuration.

*Step 8: Verify the Reset*
After reboot, use `show running-config` to confirm that there is no configuration loaded.
