Configure Advanced WLAN Settings

WLAN - Advanced Configuration Screen

Mode	Select a radio button for the mode (either Disabled, Optional or Mandatory). Disabled is the default setting.
SA Query Attempts	Use the spinner control to set the number of security association query attempts, between 1 and 10. The default value is 5.
SA Query Retry Timeout	Set the timeout (from 100-1,000 milliseconds) for waiting for a response to a SA query before resending it. The default is 201 milliseconds.

NAS Identifier	Specify what is included in the RADIUS NAS-Identifier field for authentication and accounting packets. This is an optional setting, and defaults are used if no values are provided.
NAS Port	The profile database on the RADIUS server consists of user profiles for each connected network access server (NAS) port. Each profile is matched to a user name representing a physical port. When the access point authorizes users, it queries the user profile database using a user name representative of the physical NAS port making the connection. Set the numeric port value between 0 and 4,294,967,295.
RADIUS Dynamic Authorization	Select this check box to enable the RADIUS protocol to support unsolicited messages sent from the RADIUS server. These messages allow administrators to issue change of authorization (CoA) messages, which affect session authorization, or Disconnect Messages (DM), which cause a session to terminate immediately. This option is disabled by default.

Advanced WLAN Rate Settings 2.4 GHz Screen

Advanced WLAN Rate Settings 5 GHz Screen

Define both minimum Basic and optimal Supported rates as required for the 802.11b rates, 802.11g rates and 802.11n supported by the 2.4 GHz band and the 802.11a and 802.11n rates supported by the 5.0 GHz band. These are the supported client rates within this WLAN.

802.11n MCS rates are defined as follows, both with and without short guard intervals (SGI):

Fast BSS Transition	If needed, select Fast BSS Transition to enable 802.11r fast roaming on this WLAN. This setting is disabled by default. 802.11r is an attempt to undo the burden that security and QoS added to the handoff process, and restore it to an original four message exchange process. The central application for the 802.11r standard is VOIP using mobile phones within wireless Internet networks.
Fast BSS Transition Over DS	Optionally select Fast BSS Transition Over DS to enable 802.11r over DS fast roaming on this WLAN. This setting is enabled by default.

This setting is disabled by default.

Filter Out Images	Select this option to filter images out of this WLAN‘s log files. This setting is disabled by default.
Filter Post	Select this option to filter posts out of this WLAN‘s log files. This setting is disabled by default.
Strip Query String	Select this option to filter query strings out of this WLAN‘s log files. This setting is disabled by default.

Enable	Select the check box to forward any firewall HTTP analytics to a specified syslog server for this WLAN. This setting is disabled by default.
Host	Enter a Hostname or IP Address for the syslog server to forward HTTP analytics. Hostnames cannot include an underscore character.
Port	Specify the port number utilized by the syslog server. The default port is 514.
Proxy Mode	If a proxy is needed to connect to the syslog server, select a proxy mode of either Through RF Domain Manager or Through Wireless Controller. If no proxy is needed, select None.
