By default, command
authorization is not enabled.

By default, the command level
depends on the user privilege
level. A user is authorized a
command level not higher than
the user privilege level. With
command authorization
enabled, the command level for
a login user is determined by
both the user privilege level and
AAA authorization. If a user
executes a command of the
corresponding command level,
the authorization server checks
whether the command is
authorized. If yes, the command
can be executed.
•
Before enabling command
authorization, configure the
AAA authorization server. After
you enable command
authorization, only commands
authorized by the AAA
authorization server can be
executed.
