Default System Name and Prompt Configuration
The default switch system name and prompt is Switch.
Configuring a System Name
Beginning in privileged EXEC mode, follow these steps to manually configure a system name:
When you set the system name, it is also used as the system prompt.
To return to the default hostname, use the no hostname global configuration command.
Understanding DNS
The DNS protocol controls the Domain Name System (DNS), a distributed database with which you can
map hostnames to IP addresses. When you configure DNS on your switch, you can substitute the
hostname for the IP address with all IP commands, such as ping, telnet, connect, and related Telnet
support operations.
IP defines a hierarchical naming scheme that allows a device to be identified by its location or domain.
Domain names are pieced together with periods (.) as the delimiting characters. For example, Cisco
Systems is a commercial organization that IP identifies by a com domain name, so its domain name is
cisco.com. A specific device in this domain, for example, the File Transfer Protocol (FTP) system is
identified as ftp.cisco.com.
