Configuring Service Monitoring Settings - Motorola WiNG 5.6 Reference Manual

6 - 36 WiNG 5.6 Access Point System Reference Guide
Accounting Deployment Considerations
Before defining a AAA configuration on a WLAN, refer to the following deployment guidelines to ensure the configuration is
optimally effective:
• When using RADIUS authentication, Motorola Solutions recommends the WAN port round trip delay not exceed 150 ms.
Excessive delay over a WAN can cause authentication and roaming issues. When excessive delays exist, a distributed
RADIUS service should be used.
• Motorola Solutions recommends authorization policies be implemented when users need to be restricted to specific
WLANs, or time and date restrictions need to be applied.
• Authorization policies can also apply bandwidth restrictions and assign Firewall policies to users and devices.

6.1.6 Configuring Service Monitoring Settings

Wireless LANs
When a captive portal goes offline for any reason, the Service Monitoring feature enables the captive portal administrators to
indicate to all users that the service is temporarily unavailable. As the service unavailable information is immediately displayed
to the users, users are less likely to complain.
The reasons a captive portal service becomes unavailable can be broadly classified as:
• When the RADIUS authentication server becomes unavailable. The RADIUS server could be on board the device (the
wireless controller or the access point) or external to the device.
• When the configured external captive portal service is unavailable for any reason.
• In the case of an access point, if the wireless controller to which the access point is adopted becomes unavailable.
• When a monitored DHCP server becomes unavailable.
