Management level: They are commands that influence basis operation of the
system and system support module, which plays a support role on service.
Commands of this level involve file system commands, FTP commands, TFTP
commands, XModem downloading commands, user management commands,
and level setting commands.
At the same time, login users are classified into four levels that correspond to the four
command levels respectively. After users of different levels log in, they can only use
commands at the levels that are equal to or lower than its own level.
In order to prevent unauthorized users from illegal intrusion, user will be identified when
switching from a lower level to a higher level with
super
[
level
] command. User ID
authentication is performed when users at lower level switch to users at higher level. In
other words, user password of the higher level is needed (Suppose the user has set the
super password
[
level level
] {
simple
|
cipher
}
password.
) For the sake of
confidentiality, on the screen the user cannot see the password that he entered. Only
when correct password is input for three times, can the user switch to the higher level.
Otherwise, the original user level will remain unchanged.
Different command views are implemented according to different requirements. They
are related to one another. For example, after logging in the switch, you will enter user
view, in which you can only use some basic functions such as displaying the running
state and statistics information. In user view, key in
system-view
to enter system view,
in which you can key in different configuration commands and enter the corresponding
views.
