14 CHAPTER 1: SYSTEM ACCESS
By default, terminal service is enabled on all the user interfaces.
Note the following points:
■ For the sake of security, the undo shell command can only be used on the user
interfaces other than the AUX user interface.
■ You cannot use this command on the user interface through which you log in.
■ You must confirm your privilege before using the undo shell command in any
legal user interface.
Configuring idle-timeout By default, idle-timeout is enabled and set to 10
minutes on all the user interfaces. The idle-timeout command is described in
Table 5.
Locking the User Interface The lock command locks the current user interface
and prompts the user to enter a password. This makes it impossible for others to
operate in the interface after the user leaves. The lock command is described in
Table 6.
Setting the Screen Length If a command displays more than one screen of
information, you can use the screen length command to determine how many
lines are displayed on a screen so that information can be separated in different
screens and you can view it more conveniently. The screen-length command is
described in
Table 7.
By default, the terminal screen length is 24 lines.
Setting the History-Command Buffer Size
Table 8 describes the history-command max-size command.
By default, the size of the history-command max-size command buffer is 10.
