Configuring AAA Authentication Login Methods
To configure an authentication method and method list, use the following commands.
Dell Networking OS Behavior
: If you use a method list on the console port in which RADIUS or TACACS is
the last authentication method, and the server is not reachable, Dell Networking OS allows access even
though the username and password credentials cannot be verified. Only the console port behaves this way,
and does so to ensure that users are not locked out of the system if network-wide issue prevents access to
these servers.
1
Define an authentication method-list (
method-list-name
) or specify the default.
CONFIGURATION mode
aaa authentication login {
method-list-name
| default}
method1
[
... method4
]
The default method-list is applied to all terminal lines.
Possible methods are:
•
enable
: use the password you defined using the
enable secret
,
enable password
command
in CONFIGURATION mode. In general, the
enable secret
command overrules the
enable
password
command.
•
line
: use the password you defined using the
password
command in LINE mode.
•
local
: use the username/password database defined in the local configuration.
•
none
: no authentication.
•
radius
: use the RADIUS servers configured with the radius-server host command.
•
: use the servers configured with the
tacacs-server host
command.
2 Enter LINE mode.
CONFIGURATION mode
line {aux 0 | console 0 | vty
number
[
... end-number
]}
3 Assign a
method-list-name
or the default list to the terminal line.
LINE mode
login authentication {
method-list-name
| default}
To view the configuration, use the
show config
command in LINE mode or the
show running-config
in
EXEC Privilege mode.
NOTE:
Dell Networking recommends using the
none
method only as a backup. This method does not
authenticate users. The
none
and
enable
methods do not work with secure shell (SSH).
You can create multiple method lists and assign them to different terminal lines.
Enabling AAA Authentication
To enable AAA authentication, use the following command.
• Enable AAA authentication.
CONFIGURATION mode
aaa authentication enable {
method-list-name
| default}
method1
[
... method4
]
