seconds, is the period during which the switch will not send new
requests to a server that has failed to respond to a previous request.

feature, but only if more than one server has been configured.
5.8.5 RADIUS
Authentication and Accounting Server
When a user requests network connection, a RADIUS client which receives the request will
perform an initial access negotiation with the user to obtain identity/password information. The
client then passes the information to a RADIUS server as part of an
authentication/authorization request.
The RADIUS server matches data from the authentication/authorization request with
information in a trusted database. If a match is found and the user's credentials are correct, the
RADIUS server sends an accept message to the client to grant access. If a match is not found
or a problem is found with the user's credentials, the server returns a reject message to deny
access. The NAD then establishes or terminates the user's connection. The NAD may then
forward accounting information to the RADIUS server to document the transaction; the
RADIUS server may store or forward this information as needed to support billing for the
services provided.
