Defining WLAN Security
The ESS Security Page provides information for configuring Extended Service Sets (ESS). ESS are the primary
method of organizing access points, security, and VLANs in a WLAN network. An ESS is a group of access points
that share the same Service Set Identification (SSID).
APs announce their ESS membership by SSID parameter via Beacon frames. When stations roam between the
same ESS APs, stations remain connected to the same wired network domain. Since the station remains in the
same broadcast domain and IP subnet, the station retains the same IP address while roaming between the same
ESS APs.
To configure ESS security:
1. Click WLAN > System > ESS/Security. The ESS Security Page opens:
Figure 87: ESS Security Page
The ESS Security Page contains the following fields:
• SSID — Displays the Service Set Identifier SSID for the ESS. SSIDs act as a password when a mobile device
attempts to connect to the BSS. SSIDs differentiates between WLANs, therefore all access points and
devices which comprise the specific WLAN must have the same SSID. Devices not providing a unique SSID
are denied network access. Each SSID must be unique, and can contain up-to 32 characters.
