Logging in Commands 31
Description
Use the header command to configure the system to display a header during user
log in. Use the
undo header { shell | incoming | login } command to
delete the specified header.
When the user logs in, and a connection is activated, the login header displays.
After the user successfully logs in, the
shell header displays.
The first characters in the text are regarded as the start and stop characters. After
you type in the stop character, the system will exit the header command
automatically.
If you do not want to use the control characters, you can type in text with the
same characters at the beginning and end, and press Enter.
If you press <Enter> after typing any of the three keywords shell, login and
incoming in the command, then what you type after the word header is the
contents of the login information, instead of identifying header type.
You can judge whether the initial character can be used as the header contents
this way:
1 If there is only one character in the first line and it is used as the identifier, this
initial character pairs with the ending character and is not the header contents.
2 If there are many characters in the first line but the initial and ending characters
are different, this initial character pairs with the ending character and is the
header contents.
3 There are many characters in the first line and the initial character is identical with
the ending character, this initial character is not the header contents.
Example
Configure the header of setting up a session.
Mode 1: Input in one line
<SW5500>system-view
System View: return to User View with Ctrl+Z.
[SW5500]header shell %SHELL: Hello! Welcome%
The starting and ending characters must be the same, and press the <Enter> key
to finish a line.
■ When you log on the Switch again, the terminal displays the configured session
establishment title.
[SW5500]quit
<SW5500>quit
Please press ENTER
SHELL: Hello! Welcome
The initial character "%" is not the header contents.
<SW5500>
