Table 58

Access permissions

Access type	Description of permissions
BUI	1	Login name and password. The login name is a combination of letters and digits
(HTTP server		up to 10 characters in length. The password consists of digits only. Define the
web access)		length according to the parameter “minimum password length”. Users and
		administrators can change their passwords at any time.
	2	The system does not permit multiple, simultaneous BUI sessions for the same
		user. When a user logs into the BUI, no one else can login with the same user
		ID, until the session terminates (that is, the user logs out).
		The system permits only one administration session at a time. Therefore, if
		there is an active administrator session, the system does not permit another
		administrator log in.
	3	You can access only the initial login window when you enter the BUI’s URL from
		your web browser. You cannot access any other page or file directly.
	4	The system times out and closes the session after a period of inactivity. The
		administrator defines the time-out parameter.
CLI	1	There are two login levels. Each level has a login name and password, both of

	2	The CLI does not print the password when it is being entered.
	3	The system records every successful login as an information message in the
		error log.
	4	Upon a successful login, the CLI prints the login date and time.
	5	The system times out and closes the session after a period of inactivity. The
		administrator defines the time-out parameter.
Telnet	1	Remote access using telnet requires a dedicated login name and password.
(server access)		Successful login provides access to the CLI, which, in turn, requires its own
		access and login as described above. The name and password can contain
		letters and digits.
	2	The system records every successful login as an informational message in the
		error log. The CLI terminal prints this message.
	3	The system times out and closes the session after a period of inactivity. The
		administrator defines the time-out parameter.
