26 CHAPTER 1: USING SYSTEM ACCESS COMMANDS The command levels are, from lowest to highest: ■ 0 - Visit ■ 1 - Monitoring ■ 2 - System ■ 3 - Management You can assign a priority level depending on user requirements. The commands that a user can access depend first on the access level assigned to the command and second on the access level assigned to the user interface. If the two levels are different, the access level assigned to the command has priority. For example, if the access level of a user interface is 1, but a specific user can access commands at level 3, the user can log in from this user interface, but can access commands up to and including level 3. By default: ■ ping, tracert, and telnet are at level 0 ■ display and debugging are at level 1 ■ all configuration commands are at system level 2 ■ FTP, XMODEM, TFTP and commands for file system operations are at level 3 Use the undo command-privilege view command to restore the default priority to a command. Example To configure the precedence of the command 'interface' as 0, enter the following: system-view System View: return to User View with Ctrl+Z. [SW5500]command-privilege level 0 view system interface databits Syntax databits { 7 | 8 } undo databits View User interface view Parameter 7 - Sets the data bits to 7. 8 - Sets the data bits to 8. Description Use the databits command to configure the data bits for the AUX (Console) port to either 7 or 8. By default, the value is 8. Use the undo databits command to restore the default value (8). This command can only be performed in the AUX user interface view.
