To manage device configurations, you need to list and compare configuration files on running devices, store configuration files on network servers for shared access, and perform software installations and upgrades. One of the first basic tasks is to name your router. The name of the router is considered to be the host name and is the name displayed by the system prompt. If no name is configured, the system default router name is Router. You can name the router in global configuration mode. In the example shown, the router name is set to Tokyo. You can configure a message-of-the-day banner to be displayed on all connected terminals. This banner is displayed at login and is useful for conveying messages that affect all network users, such as impending system shutdowns. To configure this message, use the banner motd command in global configuration mode.
