Cli Ports - Bay Networks 5390 Administering

CLI Ports

A CLI port has the mode parameter set to cli. In the simplest configuration, the CLI prompt displays
when the user turns on the connected terminal or presses the Return key. At this point, the user has
access to all permissible CLI commands. You can limit the number of sessions the user can initiate,
and you can configure several different security options. When configuring CLI port parameters:
• Configure the speed, the data_bits, the stop_bits, and the parity parameters to match the
terminal settings.
• Setting the type parameter to hardwired registers the user with the who database according
to the input_is_activity and output_is_activity parameter settings. If neither parameter is
set, any user on this port is invisible to who. If input_is_activity is set, when the user enters
data, the line is registered with the who database (generally used for hardwired CLI
terminals). If output_is_activity is set, the line is registered when the Model 5390 server first
sends data (generally used for hardwired printers or other slave devices). This entry is
removed on a hang-up or when the slave line is released, regardless of the input_is_activity
and output_is_activity parameter settings
• The max_session_count allows you to limit the number of sessions a user can activate
simultaneously. Setting the value to one limits the user to one session at a time. The default is
three (with a maximum of 16).
• Set the allow_broadcast parameter to N if you want to disable the display of administrative
messages generated with the na command broadcast at the port.
• The user_name and location parameters are used for administrative information. The CLI
who command displays this information. Also, the user_name is passed in the rlogin
command's connection request. If the user does not have an account on the host under the
same user name you defined with the user_name parameter, the user must issue the rlogin –l
command.
• The term_var parameter is a string that identifies the terminal type. Any value defined for
this parameter is passed with both the telnet and rlogin connection requests. If you define a
terminal type, it must be one that is valid for the host to which the user is connecting. The
Model 5390 server uses this parameter internally for the edit command only (see edit on page
C3-20 for more details).
• CLI activity timers provide simple security by resetting unattended ports. Limited resources,
like dial-in modems, are released when not in use (see Port Security on page A3-6).
The inactivity_timer specifies the amount of time in minutes that the port can be inactive
before the Model 5390 server hangs up the port. When this timer expires, all sessions are
