Wireless Configuration 5-7
1. Check the Disallow MU to MU Communications box to enable a communication block between
mobile units (MUs) using this WLAN. Such communication might be a security issue, for example, on a
corporate network. Leave this check box unchecked (default setting) to allow MU-to-MU communications
on this WLAN.
2. Check the Answer Broadcast ESS check box to enable adopted Access Ports to transmit the WLAN’s
Extended Service Set Identification (ESSID). The purpose of allowing WLANs to answer the broadcast
ESS is to identify Access Ports that are associated with the WLAN. This might be appropriate, for
example, in a customer environment, such as a “hot spot.”
Disable this option if broadcasting the WLAN’s ESSID poses a security risk, such as with a private,
corporate network. The default setting is unchecked.
3. Check the Secure Beacon check box to disallow the Access Port from broadcasting its ESSID in its
beacons. This is to prevent intruders from becoming members of the WLAN. Use this for a more secure
network.
4. Click the Apply button to save changes.
For more advanced WLAN settings see Quality of Service Configuration or Configuring Wireless LAN
Security later in this chapter.
5.3 Configuring Wireless LAN Security
The WS2000 Wireless Switch allows the administrator to set the type and level of security for each WLAN.
These security measures do not control communications from the WAN; instead, they control communication
from the clients within the WLAN.
In the Network Configuration --> Wireless --> <WLAN name> --> <WLAN Name> Security screen, the
administrator can set the user authentication method and the encryption method, as well as define a set of
rules that control which MUs can communicate through the WLAN.
