Menu Login Procedure with RADIUS

When connecting to a system, the SCU presents a login prompt. Refer to “DLP-716, Logging on

to the System” for detailed procedures.

If RADIUS authentication is enabled, the SCU contacts the provisioned RADIUS server(s) and

validates the login/password combination. It is possible that the server will respond with a

challenge request (as established by network administration). If so, a challenge message is

displayed on the screen and a challenge prompt is made available. A correct response to the

challenge will result in a completed login to the MX2820 system.

If a RADIUS challenge is not issued, immediate access is provided to the MX2820 Main Menu.

In the event that the RADIUS server can not be contacted, the local list of users stored in the

SCU is accessed for authentication.

NOTE

If RADIUS is the preferred method of authentication, the list of

users in the SCU can be disabled or deleted.

Should an authentication attempt with RADIUS fail, or an administrative password be

forgotten, ADTRAN provides a failsafe method to gain access. Refer to “DLP-716, Logging on to

the System” for detailed procedures.

TL1 Login Procedure

RADIUS authentication is available through TL1 commands. Refer to the MX2820 TL1

Reference Guide, Document Number 61186003L1-35C for information.
