The DTIM interval specifies the beacon frequency that synchronizes the AP to the network. This setting supports 1 to 255 milliseconds. Enter the amount of time, in minutes, that a client is unseen by any probes before it is deleted from the database. Enter 0 to disable ageout. Specify the total transmit rates for the 802.11g radio. The AP attempts to use the highest transmission rate to establish a mesh link. If a rate is unavailable, the AP goes through the list and uses the next highest rate. All transmission rates are selected and used. If you do not select 802.11a or 802.11g transmit rates, all rates are selected by default when you click Apply. Specify the basic rates for the 802.11g radio. Specify the transmit rates for the 802.11a radio. The AP attempts to use the highest transmission rate to establish a mesh link. If a rate is unavailable, the AP goes through the list and uses the next highest rate. All transmission rates are selected and used by default. If you do not select 802.11a or 802.11g transmit rates, all rates are selected by default when you click Apply. Specify the basic rates for the 802.11a radio. Specify the maximum number of transmit attempts. The supported range is 1 to 15. Specify the Request to Send parameter that defines the packet size sent by mesh nodes. Mesh nodes transmitting frames larger than this threshold must issue request to send (RTS) and wait for other mesh nodes to respond with clear to send (CTS) to begin transmission. This helps prevent mid-air collisions. A smaller value causes more RTS packets to be sent more often, possibly impacting bandwidth. However, a smaller value may help the system recover more quickly from interference or data packet collisions. Specify the size in bytes. Instructs the AP to use short preambles in packets. Short preambles are often standard in AP configuration. Define the maximum associations to be supported by devices configured with this SSID profile. The range is from 0 to 255. Specify whether the devices are to support wireless multimedia (WMM): voice, video, best effort (BE), or background. Enable or disable unscheduled-automatic power save delivery. U-ASPD allows the saving of WLAN client power. The WLAN client transmits frames that trigger the forwarding of data frames for a client that has been buffered at the AP for power saving purposes. A WMM client can send a Traffic Specification (TSPEC) signaling request to the AP before sending traffic of a specific AC type, such as voice. You can configure the controller so that the TSPEC signaling request from a client is ignored if the underlying voice call is not active; this feature is disabled by default. If you enable this feature, you can also configure the number of seconds that a client must wait to start the call after sending the TSPEC request (the default is one second). You enable TSPEC signaling enforcement in the VoIP Call Admission Control profile. The supported range is 0 to 3,600,000 milliseconds.
