| 6.3.4 | Router identification configuration
The configuration of network devices determines the network's behavior. 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 your 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 you do not configure a name, the system default router name will be Router. You can name the router in global configuration mode. In the example shown in the Figure, the router name is Tokyo. You can configure a message-of-the-day banner to be displayed on all connected terminals. This banner will be displayed at login and is useful for conveying messages that affect all router users (e.g. impending system shutdowns). To configure this message, use the banner motd command in the global configuration mode.
