Introduction
In this activity, you will examine and configure a standalone LAN switch. Although a switch performs basic functions in its default out-of-the-box condition, there are a number of parameters that a network administrator should modify to ensure a secure and optimized LAN. This activity introduces you to the basics of switch configuration.
Task 1: Clear an Existing Configuration on a Switch
Step 1. Enter privileged EXEC mode by typing the enable command.
Click S1 and then the CLI tab. Issue the enable command to enter the privileged EXEC mode.
Switch>enable Switch#
Step 2. Remove the VLAN database information file.
VLAN database information is stored separately from the configuration files in vlan.dat in flash. To remove the VLAN file, issue the command delete flash:vlan.dat
Switch#delete flash:vlan.dat Delete filename [vlan.dat]? [Enter] Delete flash:vlan.dat? [confirm] [Enter]
Step 3. Remove the switch startup configuration file from NVRAM.
Switch#erase startup-config Erasing the nvram filesystem will remove all configuration files! Continue? [confirm] [Enter] [OK] Erase of nvram: complete
Step 4. Verify the VLAN information was deleted.
Verify that the VLAN configuration was deleted using the show vlan command.
Switch#show vlan

The VLAN information is still on the switch. Follow the next step to clear it.
Step 5. Reload the switch.
At the privileged EXEC mode prompt, enter the reload command to begin the process.
Switch#reload Proceed with reload? [confirm] [enter] %SYS-5-RELOAD: Reload requested by console. Reload Reason: Reload Command. <output omitted> Press RETURN to get started! [Enter] Switch>
