Configuring a System Name and Prompt
You configure the system name on the switch to identify it. By default, the system name and prompt are
Switch.
If you have not configured a system prompt, the first 20 characters of the system name are used as the
system prompt. A greater-than symbol [>] is appended. The prompt is updated whenever the system
name changes, unless you manually configure the prompt by using the prompt global configuration
command.
Note For complete syntax and usage information for the commands used in this section, refer to the Cisco IOS
