4 Working with wireless communities and
authentication
Overview
The M220 allows you to create up to eight wireless communities. Each wireless community
defines the settings for a distinct wireless network, with its own network name (SSID), settings
for wireless protection, user authentication, VLANs, and more.
For example, in the following scenario, four wireless communities are defined. Each wireless
community is configured with a different wireless network name (SSID).
Even though multiple wireless communities are in use, all wireless users are on the same
network (192.168.5.0). This means that all wireless users can reach resources on the corporate
network. However, communication between wireless users may or may not be possible,
depending on the configuration settings defined for each wireless community.
Configuring global RADIUS servers
M220 communities can use third-party RADIUS servers to validate user login credentials for the
WPA enterprise, 802.1X, or MAC-based authentication options.
The M220 enables you to define up to four IPv4 or four IPv6 global RADIUS servers, which can
be shared by each wireless community.
