Disable AAA-based Authentication for Console
A
noconsole
keyword for the Global Configuration mode
local-user allow-aaa-authentication
command
disables AAA-based authentication on the Console line.
configure
local-user allow-aaa-authentication noconsole
exit
Since local-user authentication is always performed before AAA-based authentication and
local-user
allow-aaa-authentication noconsole
is enabled, the behavior is the same as if
no local-user
allow-aaa-authentication
is configured. There is no impact on vty lines.
This command does not apply for a Trusted build because the local-used database is unavailable.
Important
Disable Authentication at the Context Level
When you enable
aaa
in the Global Configuration mode, authentication is automatically
applied to all contexts (local and non-local). In some network deployments you may wish to disable
services for a specific context(s).
You can use the
no aaa
Context Configuration command to disable services within a
context.
configure
context ctx_name
no aaa
Use the
aaa
Context Configuration command to enable services within a context where
it has been previously disabled.
AAA services must be enabled in the Global Configuration mode (all contexts) before you
can selectively disable the services at the context level. You cannot selectively enable services
at the context level when it has not been enabled globally.
Important
Limit local-user Login on Console/vty Lines
As a security administrator when you create a StarOS user you can specify whether that user can login through
the Console or vty line. The
[ noconsole | novty ]
keywords for the Global Configuration mode
local-user
username
command support these options.
configure
local-user username <username> [ noconsole | novty ]
exit
The
noconsole
keyword prevents the user from logging into the Console port. The
novty
keyword prevents
the user from logging in via an SSH or telnet session. If neither keyword is specified access to both Console
and vty lines is allowed.
