NOTE
l The system supports commands that contain a maximum of 512 characters. A command does not have
to be entered in full, as long as the part of the command entered is unique within the system. For
example, to use the display current-configuration command, entering d cu, di cu, or dis cu will run
the command. Entering d c or dis c will not run the command, because these entries are not unique to
the command.
l The system saves the complete form of incomplete commands to configuration files. Saved commands
may have more than 512 characters. When the system is restarted, incomplete commands cannot be
restored. Therefore, pay attention to the full length of incomplete commands before saving them.
