Step $8$: Encrypt the enable and console passwords.

As you noticed in Step $7,$ the enable secret password was encrypted, but the enable and console passwords were still in plain text. We will now encrypt these plain text passwords using the service password$-$encryption command.

S$1$# config t

S$1($config$)$# service password$-$encryption

S$1($config$)$# exit

If you configure any more passwords on the switch, will they be displayed in the configuration file as plain text or in encrypted form? Explain.

Part $3$: Configure a MOTD Banner

Step $1$: Configure a message of the day $($MOTD$)$ banner.

The Cisco IOS command set includes a feature that allows you to configure messages that anyone logging onto the switch sees. These messages are called message of the day, or MOTD banners. Enclose the banner text in quotations or use a delimiter different from any character appearing in the MOTD string.

S$1$# config t

S$1($config$)$# banner motd "This is a secure system. Authorized Access Only!"

S$1($config$)$# exit

$\%$SYS$-5-$CONFIG$\_$I: Configured from console by console S$1$#

When will this banner be displayed?

Why should every switch have a MOTD banner?
