Sample applications 22
Authenticating to an authentication server 23
Figure 2 6 on page 22 shows an example of a network configuration that uses a wireless controller access points poe switch and a remote authentication dial in user service radius for authentication in this configuration the radius server authenticates users before they gain access to the wlan 23
In this configuration 23
Same ip address range assigned to that subnet 23
Switch the uplink of the poe switch connects to a layer 3 switch or router that provides internet access 23
The access points and wireless controller are connected in the same subnet and use the 23
The access points and wireless controller are connected to a power over ethernet poe 23
There are no routers between the access points and the wireless controller 23
There is a shared secret key exchanged between the access point and radius server 23
To configure the wireless controller for wpa or wpa wpa2 security perform the basic configuration procedure described in chapter 3 and then use the procedure below to configure the wireless controller for wpa or wpa wpa2 security 23
Types of authentication such as kerberos have other settings that must be configured 23
User and user privileges are specified in the radius database servers using other 23
Web authentication is a feature that denies a client access to the network until that client supplies a valid username and password 23
To configure the wireless controller for this configuration use the procedure below 24
Logging in to a captive portal 25
After installing the wireless controller proceed to chapter 3 to perform basic configuration procedures 26
To configure an interface for captive portal access perform the basic configuration procedure described in chapter 3 and then use the procedure below to configure an interface for captive portal access you can associate a configured captive portal with a specific physical interface or wireless network ssid 26
