Setting the System Name and System Prompt on the Switch
Setting the System Name and System Prompt on the Switch
The system name on the switch is a user-configurable string that is used to identify the device. The
default configuration has no system name configured.
If you do not manually configure a system name, the system name is obtained through the Domain Name
System (DNS) if you configure the switch as follows:

•
If the DNS lookup is successful, the DNS host name of the switch is configured as the system name of
the switch and is saved in NVRAM (the domain name is removed).
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 using the set prompt command.
