Logging In Through SSH
Secure Shell (SSH) offers an approach to logging into a remote device securely. With encryption and
strong authentication, it protects devices against attacks such as IP spoofing and plain text password
interception. For the security features provided by SSH, see
SSH2.0
in the
Security Configuration
Guide
.
At present, only APs that support 802.11n support SSH login.
Configuring Command Authorization
By default, command level for a login user depends on the user level. The user is authorized the
command with the default level not higher than the user level. With the command authorization
configured, the command level for a login user is decided by both the user level and AAA authorization.
If a user executes a command of the corresponding user level, the authorization server checks whether
the command is authorized. If yes, the command can be executed.
The authorization server checks the commands authorized for users through the username, and thus
the command authorization configuration involves four steps:
Step1
Configure the authentication mode as
scheme
(In other words,
use username and password are
required for authentication) when users log in.
Step2
Enable command authorization. For more information, see the following table.
Step3
Configure a RADIUS scheme. Specify the IP addresses of the RADIUS authorization servers and
other related parameters. For more information, see
AAA
in the
Security Configuration Guide
.
Step4
Configure the ISP domain to use the RADIUS scheme for command line users. For more information,
See
AAA
in the
Security Configuration Guide
.
Follow these steps to enable command authorization:
