Setting the Hostname, Domain Name, and the enable and Telnet Passwords

To set the hostname and domain name and set the enable and Telnet passwords, perform the following
steps:
Step1 In ASDM, choose Configuration > Device Setup > Device Name/Password.
Step2 Enter the hostname. The default hostname depends on your platform.
The hostname appears in the command line prompt, and if you establish sessions to multiple devices, the
hostname helps you keep track of where you enter commands. The hostname is also used in syslog
messages.
For multiple context mode, the hostname that you set in the system execution space appears in the
command line prompt for all contexts. The hostname that you optionally set within a context does not
appear in the command line; it can be used for a banner.
Step3 Enter the domain name. The default domain name is default.domain.invalid.
The ASA appends the domain name as a suffix to unqualified names. For example, if you set the domain
name to “example.com,” and specify a syslog server by the unqualified name of “jupiter,” then the ASA
qualifies the name to “jupiter.example.com.”
