A user can switch to a privilege level equal to or lower than the current one unconditionally and is not
required to input the password (if any). A user is required to input the password (if any) to switch to a
higher privilege level for security sake.
The authentication falls into one of the following four categories: local , scheme , local scheme , and
scheme local . You can specify the authentication mode as required.
When a user switches to a privilege level higher than the current one, the switch procedure varies with
authentication modes:
z
local : In this mode, after the user executes the command to switch the user privilege level, the
system asks the user to input the local switch authentication password set with the super
password command. If the user passes the authentication, the user privilege level will be
switched successfully; otherwise, the user privilege level will remain unchanged.
z
scheme : In this mode, after the user executes the command to switch the user privilege level, the
system asks the user to input this user’s switch password configured on the AAA server. If the
user passes the AAA authentication, the user privilege level will be switched successfully;
otherwise, the user privilege level will remain unchanged.
z
local scheme : In this mode, after the user executes the command to switch the user privilege
level, the system asks the user to input the local switch authentication password. With the local
switch authentication password configured, if the user passes the authentication, the user
privilege level will be switched successfully; otherwise, the user privilege level will remain
unchanged. With no local switch authentication password configured, the AAA authentication is
performed: if the user passes the AAA authentication, the user privilege level will be switched
successfully; otherwise, the user privilege level will remain unchanged.
z
scheme local : In this mode, after the user executes the command to switch the user privilege
level, the system asks the user to input this user’s switch password configured on the AAA server.
If the user passes the AAA authentication, the user privilege level will be switched successfully;
otherwise, the user privilege level will remain unchanged. If the AAA configuration is invalid or the
AAA server does not respond, the authentication requiring the local password is performed: if the
user passes the authentication, the user privilege level will be switched successfully; otherwise,
the user privilege level will remain unchanged.
If the authentication mode is set to scheme (performs authorization and authentication of AAA) when
the user logs in to the switch (that is, username and password are required when the user logs in), the
AAA authentication is performed when the user switches his privilege level: the system asks the user to
input the privilege level switch password; after the user inputs the password, the device uses the
username used to log in to the switch and the privilege level switch password to perform the privilege
level switch authentication.
