Radius authentication can be used to authenticate a user logging into the appliance via CLI. This provides each user with a unique ID and provides external control for user access.

To configure RADIUS on an appliance:

1. Access the appliance console using ssh.

2. Log into the console using the credentials nsadmin/nsappliance. An nsshell opens.

3. Enter configure to enter the nsshell configure mode.

4. Configure the RADIUS server using these commands:

set radius-server hostname <RADIUS server hostname>
save

### Note

The timeout value can be set to a minimum of 1 second and maximum of 60 seconds.

auth nsshell-user add username <username>
Usernames can only contain lower case alphabets, numbers, underscores, and $. They should start with an alphabet and can end with a$.
6. Additional users can be added one at a time using this command. To delete a user, replace add with delete in the above command.
