Use this option to select how to administer remote access to the Rack PDU.
The Rack PDU supports the authentication and authorization functions of RADIUS
(Remote Authentication Dial-In User Service).
• When a user accesses the Rack PDU or other network-enabled device that has
RADIUS enabled, an authentication request is sent to the RADIUS server to
determine the user’s permission level.
• RADIUS user names used with the Rack PDU are limited to 32 characters.
Select one of the following:
• Local Authentication Only : RADIUS is disabled. Local authentication is enabled.
• RADIUS, then Local Authentication : RADIUS and local authentication are enabled.
Authentication is requested from the RADIUS server first. If the RADIUS server fails
to respond, local authentication is used
.
• RADIUS Only : RADIUS is enabled. Local authentication is disabled.
For information about local authentication (not using the centralized
authentication of a RADIUS server), see the
Appendix B: Security Handbook .
If RADIUS Only is selected, and the RADIUS server is unavailable,
improperly identified, or improperly configured, remote access is
unavailable to all users. You must use a serial connection to the command
line interface and change the
access setting to local or radiusLocal to
regain access. For example, the command to change the access setting to
local would be:
radius -a local
