Chapter 3: Terminal Menu Operation and Structure

Security/When

Write security: 1; Read security: 2

The Express XL/XLT can be configured to authenticate the PPP peer (using the above method) for incoming calls using Answer Only (def), or for outgo- ing and incoming calls using Originate and Answer.

Security/Radius Server

The parameters for the radius server are configured in this menu. The RADI- US server can be used for authenticating a PPP peer (if defined under Security/ Authentication) and for Telnet server sessions.

Radius Server/Primary Server

Write security: 1; Read security: 2

This is the IP address of the first RADIUS server that the Express XL/XLT should attempt to communicate with when authenticating a PPP peer.

Radius Server/Secondary Server

Write security: 1; Read security: 2

This is the IP address of the back-up RADIUS server that the Express XL/XLT should attempt to communicate with when the primary server does not re- spond.

Radius Server/UDP Port

Write security: 1; Read security: 2

This is the UDP port that the Express XL/XLT should use when communicat- ing with the RADIUS server. The default is 1645, which is the commonly used port.

Radius Server/Secret

Write security: 0; Read security: 1

The RADIUS server and Express XL/XLT share this text string, which is used by the RADIUS sever to authenticate the Express XL/XLT that is the RADIUS client. The factory default is to not use a secret.
