Manage the RADIUS settings
RADIUS servers provide additional security for networks. The RADIUS server maintains a
user database, which contains per-user authentication information. The switch passes
information to the configured RADIUS server, which can authenticate a user name and
password before authorizing use of the network. RADIUS servers provide a centralized
authentication method for the following:
• W
eb access
• Access control port (802.1X)
Configure the global RADIUS server settings
You can add information about one or more RADIUS servers on the network.
If you configure multiple RADIUS servers, consider the maximum delay time when you
specify the maximum number of retransmissions (that is, the value that you enter in the Max
Number of Retransmits field) and the time-out period (that is, the value that you enter in the
T
imeout Duration field) for RADIUS:
For one RADIUS server, a retransmission does not occur until the configured time-out
period expires without a response from the RADIUS server
. In addition. the maximum
number of retransmissions for one RADIUS server must pass before the switch attempts
the next RADIUS server.
