3• Level changes can cause maintenance, operation, and security problems. H3C recommends thatyou use the default command level or that you modify the command level under the guidance ofprofessional staff.• The command specified in the command-privilege command must be complete, and has validarguments. For example, the default level of the tftp server-address { get | put | sget }source-filename [ destination-filename ] [ source { interface interface-type interface-number | ipsource-ip-address } ] command is 3. After the command-privilege level 0 view shell tftp 1.1.1.1 puta.cfg command is executed, when users with the user privilege level of 0 log in to the switch, theycan execute the tftp server-address put source-filename command (such as the tftp 192.168.1.26 putsyslog.txt command), but cannot execute the command with the get, sget or source keyword, andcannot specify the destination-filename argument.• The command specified in the undo command-privilege view command can be incomplete. Forexample, after the undo command-privilege view system ftp command is executed, all commandsstarting with the keyword ftp (such as ftp server acl, ftp server enable, and ftp timeout) are restoredto their default level. If you have modified the level of commands ftp server enable and ftp timeout,and you want to restore only the ftp server enable command to its default level, you should use theundo command-privilege view system ftp server command.• If you modify the command level of a command in a specified view from the default command levelto a lower level, remember to modify the command levels of the quit command and thecorresponding command that is used to enter this view. For example, the default command level ofcommands interface and system-view is 2 (system level). If you want to make the interfacecommand available to the level 1 users, you need to execute the following three commands:command-privilege level 1 view shell system-view, command-privilege level 1 view systeminterface GigabitEthernet 1/0/1, and command-privilege level 1 view system quit. Then, the level1 users can enter system view, execute the interface ethernet command, and return to user view.Examples# Set the command level of the interface command to 0 in system view. system-view[Sysname] command-privilege level 0 view system interfacedisplay clipboardSyntaxdisplay clipboard [ | { begin | exclude | include } regular-expression ]ViewAny viewDefault level1: Monitor levelParameters|: Filters command output by specifying a regular expression.
