3 Click the Create button (if necessary) to launch the New WLAN screen. Use the New WLAN screen to
define the properties of a new WLAN that would display and be selectable within the Wireless
Configuration screen. For additional information, see
page 148.
4 Click the Edit button (if necessary) to launch the Edit WLAN screen. Use the Edit WLAN screen to
revise the properties of an existing WLAN that would continue display and be selectable within the
Wireless Configuration screen. For additional information, see
on page 148.
5 Consider using the Delete button to remove an existing WLAN if it has become outdated and is no
longer required or if you are coming close the maximum 16 WLANs available per access point.
6 Refer to the Proxy-ARP Disable field to enable/disable Proxy AP support. Proxy ARP is disabled by
default.
When enabled, any system on the wireless network that ARPs for the IP address of an associated
MU receives an ARP reply from the Access Point stating the requesting system should be sending
packets destined for the MU to Access Point instead. In turn, the Access Point forwards the
requesting packets to the target MU. Through this process, the Access Point can pass ARP requests
in both directions, making an MU appear to be connected to a public network even though it's on a
private network, hidden behind the Access Point.
Select the following options as required:
a Select Dynamic for the Access Point to respond to an ARP request for its MU IP addresses using
an ARP response and drop the original ARP request packet.
b Select Strict for the Access Point to respond to ARP request for its MU IP addresses using an ARP
response and drop the original ARP request packet (like the dynamic option). However, with the
strict option, the Access Point will drop the ARP request to wireless (WLAN interfaces not the
mesh interface) if the ARP request is for the IP address of non-MUs or if gratuitous ARP requests
are coming from the MU. This helps reduce unnecessary ARP traffic and improve throughput
within the Access Point managed wireless network.
7 Click Logout to securely exit the Access Point applet. A prompt displays confirming the logout before
the applet is closed.

Creating/Editing Individual WLANs

If the WLANs displayed within the Wireless Configuration screen do not satisfy your network
requirements, you can either create a new WLAN or edit the properties of an existing WLAN.

The Security Policy field displays the security profile
configured for the target WLAN. For information on
configuring security for a WLAN,
The QoS Policy field displays the quality of service
currently defined for the WLAN. This policy outlines which
data types receive priority for the user base comprising the
WLAN. For information on QoS configuration for the
WLAN, see "Setting the WLAN Quality of Service (QoS)
Policy" on page 156.
