Configuring Network Security Configuration Examples breaks down and doesn't respond to the authentication request, RADIUS Server 2 will work, so as to ensure the stability of the authentication system. Figure 13-16 Network Topology Administrator Management Network Switch RADIUS Server 1 192.168.0.10/24 Auth Port:1812 RADIUS Server 2 192.168.0.20/24 Auth Port: 1812 13.5.2 Configuration Scheme To implement this requirement, the senior administrator can create the login account and the Enable password on the two RADIUS servers, and configure the AAA feature on the switch. The IP addresses of the two RADIUS servers are 192.168.0.10/24 and 192.168.0.20/24; the authentication port number is 1812; the shared key is 123456. The overview of configuration on the switch is as follows: 1) Globally enable AAA. 1) Add the two RADIUS servers on the switch. 2) Create a new RADIUS server group and add the two servers to the group.
