Telnet/User List

Up to four users can be configured for access to the Express XL/XLT. Each user can be assigned a privilege and time out.

User List/Name

Write security: 1; Read security: 3

A text string of the user name for this session.

User List/Authen Method

Write security: 1; Read security: 3

The user can be authenticated in two ways:

Password - The Password field is used to authenticate the user.

Radius - The Radius client is used for authenticating the user.

User List/Password Write security: 0; Read security: 3

When the authenticating method is password, this text string is used for the password.

User List/Idle Time Write security: 1; Read security: 3

When set to non-zero, the session is automatically logged out when no activity occurs for this amount of time. The range is 0 to 255 and is in minutes. The default is 10 minutes, and a setting of 0 will never time out the session. When a timeout occurs during an edit session, all changes are saved.

User List/Level

Write security: 0; Read security: 1

This is the security level privilege that is assigned for this user. See Security Levels on page 33 for an explanation of what those levels imply. Level 0 is the default.
