Wireless Array
Configuring the Wireless Array 257
Configuration encryption settings have the same parameters as those
described in “Procedure for Configuring Network Security” on page 231.
The external RADIUS and accounting settings are configured in the same
way as for an external RADIUS server (see “Procedure for Configuring an
External RADIUS Server” on page 235). Note that external RADIUS
servers may be specified using IP addresses or domain names.
13. Roaming: For this SSID, select whether to enable fast roaming between
IAPs or Arrays at L2&L3 (Layer 2 and Layer 3), at L2 (Layer 2 only), or
disable roaming (Off). You may only select fast roaming at Layers 2 and 3
if this has been selected in Global Settings (IAP). See “Understanding Fast
Roaming” on page 278.
14. WPR (Web Page Redirect): Check the checkbox to enable the Web Page
Redirect functionality, or clear it to disable this option. If enabled, WPR
configuration fields will be displayed under the SSID Limits section. This
feature may be used to provide an alternate mode of authentication, or to
simply display a splash screen when a user first associates to the wireless
network. After that, it can (optionally) redirect the user to an alternate
URL. For example, some wireless devices and users may not have a
correctly configured 802.1x (RADIUS) supplicant. Utilizing WPR’s Web-
based login, users may be authenticated without using an 802.1x
supplicant. See “Web Page Redirect Configuration Settings” on page 260
for details of WPR usage and configuration.
You may specify “Whitelist” entries—a list of web sites to which users
have unrestricted access, without needing to be redirected to the WPR
page first. See “Whitelist Configuration for Web Page Redirect” on
page 264 for details.
15. Fallback: Network Assurance checks network connectivity for the Array.
When Network Assurance detects a failure, perhaps due to a bad link or
WDS failure, if Fallback is set to Disable the Array will automatically
disable this SSID. This will disassociate current clients, and prevent new

When using WPR, it is particularly important to adhere to the SSID
naming restrictions detailed in Step 1.
