RADIUS Authentication and Accounting
Configuring the Switch for RADIUS Authentication
•- Determine how many times you want the switch to try contacting a RADIUS server before trying another RADIUS
server or quitting. (This depends on how many RADIUS servers you have configured the switch to access.)
•- Determine whether you want to bypass a RADIUS server that fails to respond to requests for service. To shorten
authentication time, you can set a bypass period in the range of 1 to 1440 minutes for non-responsive servers. This
requires that you have multiple RADIUS servers accessible for service requests.
•- Optional: Determine whether the switch access level (Manager or Operator) for authenticated clients can be set by
a Service Type value the RADIUS server includes in its authentication message to the switch. (Refer to “2. Enable the
(Optional) Access Privilege Option” on page 6-12.)
• Configure RADIUS on the server(s) used to support authentication on the switch.
