MULTIPLE SSID AND VLAN SUPPORT
The LPS-20x provides support for multiple Service Set Identifiers (SSIDs) (Figure 13). This allows the wireless
network to be segmented into multiple distinct entities, each with its own SSID. This feature is very useful when
combined with Virtual Local Area Network (VLAN) support. For example, in this scenario public and private users
share the same infrastructure with complete security.
Figure 13. Multiple SSID amd VLAN Support
The wireless network is split into two WLANs: public and private:
• The Public WLAN maps authentication traffic between the LPS-20x and the Access Controller on VLAN
60. Once a user is authenticated, traffic to the Internet does not use a VLAN.
• The Private WLAN maps authentication traffic between the LPS-20x and the RADIUS Server on VLAN
70. Once a user is authenticated, traffic to the Internet or Corporate Intranet is mapped across VLANs 51,
52, 53.
