aaa authentication enable default group
Overview
This command enables AAA authentication to determine the privilege level a user
can access for passwords authenticated against the server.
Use the
no
variant of this command to disable privilege level authentication.
Syntax
aaa authentication enable default group [local] [none]
no aaa authentication enable default
Default
Local privilege level authentication is enabled by default (
aaa authentication
enable default local
command).
Mode
Global Configuration
Usage
A user is configured on a server with a maximum privilege level. When
they enter the
enable (Privileged Exec mode)
command they are prompted for an
enable password which is authenticated against the server. If the
password is correct and the specified privilege level is equal to or less than the
users maximum privilege level, then they are granted access to that level. If the
user attempts to access a privilege level that is higher than their maximum
configured privilege level, then the authentication session will fail and they will
remain at their current privilege level.
NOTE
:
If both
local
and
none
are specified, you must always specify
local
first.
If the server goes offline, or is not reachable during enable password
authentication, and command level authentication is configured as:
•
aaa authentication enable default group
then the user is never granted access to Privileged Exec mode.
•
aaa authentication enable default group local
then the user is authenticated using the locally configured enable password,
which if entered correctly grants the user access to Privileged Exec mode. If
no enable password is locally configured (
enable password
command),
then the enable authentication will fail until the server becomes
available again.
Parameter
Description
local
Use the locally configured enable password (
enable password
command) for authentication.
none
No authentication.
