<1-4094> VLAN interface number
[Sysname] interface vlan-interface 1 ?

Where, <cr> indicates that there is no parameter at this position. The command is then repeated in the
next command line and executed if you press Enter .
4) Enter a character string followed by a ? . All the commands starting with this string are displayed.
<Sysname> c?
cd
clock

5) Enter a command followed by a character string and a ?. All the keywords starting with this string
are listed.
<Sysname> display cl?
clipboard
clock
cluster
6) Press Tab after entering the first several letters of a keyword to display the complete keyword,
provided these letters can uniquely identify the keyword in this command. If several matches are
found, the complete keyword which is matched first is displayed (the matching rule is: the letters
next to the input letters are arranged in alphabetic order, and the letter in the first place is matched
first.). If you repeatedly press Tab , all the keywords starting with the letter that you enter are
displayed in cycles, and you can select the keywords needed.
Synchronous Information Output
Synchronous information output refers to the feature that if the user’s input is interrupted by system
output, then after the completion of system output the system will display a command line prompt and
your input so far, and you can continue your operations from where you were stopped.
You can use the info-center synchronous command to enable synchronous information output. For
the detailed description of this function, refer to Information Center Configuration in the System Volume .
Undo Form of a Command
Adding the keyword undo can form an undo command. Almost every configuration command has an
undo form. undo commands are generally used to restore the system default, disable a function or
cancel a configuration. For example, the info-center enable command is used to enable the
information center, while the undo info-center enable command is used to disable the information
center. (By default, the information center is enabled.)
Editing Features
The CLI provides the basic command editing functions and supports multi-line editing. When you
execute a command, the system automatically goes to the next line if the maximum length of the
command is reached. You cannot press Enter to go to the next line; otherwise, the system will
automatically execute the command. The maximum length of each command is 510 characters. Table
1-4 lists these functions.
