22 CHAPTER 1: SYSTEM ACCESS
Configuring the Terminal Attributes
The following commands can be used for configuring the terminal attributes,
including enabling/disabling terminal service, disconnection upon timeout,
lockable user interface, configuring terminal screen length and history command
buffer size.
Perform the following configuration in user interface view. Perform the lock
command in user view.
Enabling and Disabling Terminal Service After the terminal service is
disabled on a user interface, you cannot log in to the Switch 7750 through the
user interface. However, if a user is logged in through the user interface before
disabling the terminal service, the user can continue operation. After the user logs
out, the user cannot log in again. In this case, the user can log in to the Switch
through the user interface only when the terminal service is enabled again. Use
the commands described in
Table 6 to enable or disable terminal service.
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.
