This example uses the following hardware and software components:
Junos OS Release 9.0 or later for EX Series switches
One EX Series switch acting as an authenticator port access entity (PAE). The ports
on the authenticator PAE form a control gate that blocks all traffic to and from
supplicants until they are authenticated.
One RADIUS authentication server that supports 802.1X. The authentication server
acts as the backend database and contains credential information for hosts
(supplicants) that have permission to connect to the network.
Before you connect the server to the switch, be sure you have:
Performed basic bridging and VLAN configuration on the switch. See "Example: Setting
Up Basic Bridging and a VLAN for an EX Series Switch" on page 1305.
Configured users on the RADIUS authentication server.
The EX Series switch acts as an authenticator Port Access Entity (PAE). It blocks all
traffic and acts as a control gate until the supplicant (client) is authenticated by the
server. All other users and devices are denied access.
Figure 51 on page 2547 shows one EX4200 switch that is connected to the devices listed
in Table 332 on page 2548.
