■ Authenticate users on all ports to control their accesses to the Internet. The
switch operates in MAC address-based access control mode. The access control
mode is MAC-address-based.
■ All supplicant systems that pass the authentication belong to the default
domain named "aabbcc.net". The domain can accommodate up to 30 users.
As for authentication, a supplicant system is authenticated locally if the RADIUS
server fails. And as for accounting, a supplicant system is disconnected by force
if the RADIUS server fails. The name of an authenticated supplicant system is
not suffixed with the domain name. A connection is terminated if the total size
of the data passes through it during a period of 20 minutes is less than 2,000
bytes. All connected clients belong to the same default domain: aabbcc.net,
which accommodates up to 30 clients. Authentication is performed either on
the RADIUS server, or locally ( in case that the RADIUS server fails to respond).
A client is disconnected in one of the following two situations: RADIUS
accounting fails; the connected user has not included the domain name in the
username, and there is a continuous below 2000 bytes of traffic for over 20
minutes.
■ The switch is connected to a server comprising of two RADIUS servers whose IP
addresses are 10.11.1.1 and 10.11.1.2. The RADIUS server with an IP address
of 10.11.1.1 operates as the primary authentication server and the secondary
accounting server. The other operates as the secondary authentication server
and primary accounting server. The password for the switch and the
authentication RADIUS servers to exchange message is "name". And the
password for the switch and the accounting RADIUS servers to exchange
message is "money". The switch sends another packet to the RADIUS servers
again if it sends a packet to the RADIUS server and does not receive response
for 5 seconds with a maximum number of retries of 5. And the switch sends a
real-time accounting packet to the RADIUS servers once in every 15 minutes. A
user name is sent to the RADIUS servers with the domain name truncated.
Connected to the switch is a server group comprised of two RADIUS servers
whose IP addresses are 10.11.1.1 and 10.11.1.2 respectively, with the former
