Setting the Hostname, Domain Name, and the enable and Telnet Passwords
To set the hostname, domain name, and the enable and Telnet passwords, perform the following steps:
Step 1 In ASDM, choose
Configuration > Device Setup > Device Name/Password
Step 2 Enter the hostname. The default hostname is “asa.”
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.
Step 3 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.”
Note In multiple context mode, the Enable Password area only appears in contexts; it does not appear in the system execution space.
Step 4 Change the privileged mode (enable) password.
The enable password lets you access privileged EXEC mode after you log in. Also, this password is used to access ASDM as the default user, which is blank. The default user shows as “enable_15” in the User Accounts pane. (If you configure user authentication for enable access, then each user has a separate password, and this enable password is not used. In addition, you can configure authentication for HTTP/ASDM access.)
Step 5 Enter the old password.
Step 6 Enter the new password.
Step 7 Confirm the new password.
Note In multiple context mode, the Telnet Password area only appears in contexts; it does not appear in the system execution space.
Step 8 Change the login password for Telnet access.
The Telnet password sets the login password. 9.0(1): By default, it is “cisco.” 9.0(2) and later: There is no default password. The login password lets you access EXEC mode if you connect to the ASA using a Telnet session. (If you configure user authentication for Telnet access, then each user has a separate password, and this login password is not used.)
Step 9 Enter the old password.
Step 10 Enter the new password.
Step 11 Confirm the new password.
