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
or
enable password
command in
CONFIGURATION mode.
•
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
]
–
default
: uses the listed authentication methods that follow this argument as the default list of methods when a user logs
in.
–
method-list-name
: character string used to name the list of enable authentication methods activated when a user logs
in.
–
method1
[
... method4
]
: any of the following: RADIUS, TACACS, enable, line, none.
If you do not set the default list, only the local enable is checked. This setting has the same effect as issuing an
aaa
authentication enable default enable
command.
Enabling AAA Authentication — RADIUS
To enable authentication from the RADIUS server, and use TACACS as a backup, use the following commands.
1.
Enable RADIUS and set up TACACS as backup.
