Switched Rack PDU
101
RADIUS
RADIUS (Remote Authentication Dial-In User Service) is an authentication,
authorization, and accounting service. APC supports the authentication and
authorization functions of RADIUS. Use this option to centrally administer
remote access for each Rack PDU.
When a user accesses the Switched Rack PDU, it sends an authentication
request to the RADIUS server to determine the user’s permission level.
RADIUS user names are limited to 32 characters.
For more information on user permission levels, see Types of
user accounts.
The RADIUS server and the Rack PDU must be configured
before RADIUS authentication and authorization will operate
properly.
RADIUS servers use port 1812 by default to authenticate
users. To use a different port, add a colon followed by the
new port number to the end of the RADIUS server name or
IP address.
