Now you are ready to change the password on the module. Issue the write terminal command or the show running-config command to display the saved configuration on the module.
If any of the interfaces that were in use before the password recovery show " down", issue the no shutdown command on that interface to bring the interface up. Issue the show ip interface brief command to make sure that the interfaces that were in use earlier show an " up up" status.

As a best practice, Cisco recommends that you have a backup copy of the configuration of all Cisco devices at the TFTP server or a Network Management server. Tip: Configuration of the switch is not lost if the procedure is followed as mentioned. For details on the switch console connection, refer to Connecting a Modem to the Console Port on Catalyst Switches. Note: Make sure that you have physical access to the switch and that you use console access to the Supervisor Engine module while you perform these steps.
