[. . . ] cwMax The value specified for the Maximum Contention Window is the upper limit (in (Maximum Contention milliseconds) for the doubling of the random backoff value. This doubling continues Window) until either the data frame is sent or the Maximum Contention Window size is reached. Once the Maximum Contention Window size is reached, retries will continue until a maximum number of retries allowed is reached. Valid values for cwMax are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for cwMax must be higher than the value for cwMin. Max. Burst Length The Max. Burst Length is an AP EDCA parameter and only applies to traffic flowing from the AP to the client station. This value specifies (in milliseconds) the maximum burst length allowed for packet bursts on the wireless network. A packet burst is a collection of multiple frames transmitted without header information. The decreased overhead results in higher throughput and better performance. Valid values for maximum burst length are 0. 0 through 999.
Wi-Fi Multimedia Settings
Wi‐Fi MultiMedia
Wi‐Fi MultiMedia (WMM) is enabled by default. With WMM enabled, QoS prioritization and coordination of wireless medium access is on. With WMM enabled, QoS settings on the UAP control downstream traffic flowing from the AP to client station (AP EDCA parameters) and the upstream traffic flowing from the station to the AP (station EDCA parameters). Disabling WMM deactivates QoS control of station EDCA parameters on upstream traffic flowing from the station to the AP. With WMM disabled, you can still set some parameters on the downstream traffic flowing from the AP to the client station (AP EDCA parameters). To disable WMM extensions, click Disabled. To enable WMM extensions, click Enabled.

Station EDCA Parameters
Description
Queues are defined for different types of data transmitted from station‐to‐AP: • Data 0 (Voice) — Highest priority queue, minimum delay. Time‐sensitive data such as VoIP and streaming media are automatically sent to this queue. • Data 1(Video) — Highest priority queue, minimum delay. Time‐sensitive video data is automatically sent to this queue. • Data 2 (best effort) — Medium priority queue, medium throughput and delay. Most traditional IP data is sent to this queue. • Data 3 (Background) — Lowest priority queue, high throughput. Bulk data that requires maximum throughput and is not time‐sensitive is sent to this queue (FTP data, for example). AIFS The Arbitration Inter‐Frame Spacing (AIFS) specifies a wait time for data frames. (Inter‐Frame Space) The wait time is measured in slots. Valid values for AIFS are 1 through 255. cwMin This parameter is used by the algorithm that determines the initial random backoff (Minimum Contention wait time (window) for retry of a data transmission during a period of contention for Unified Access Point resources. The value specified here in the Minimum Contention Window) Window is the upper limit (in milliseconds) of a range from which the initial random backoff wait time will be determined. The first random number generated will be a number between 0 and the number specified here. If the first random backoff wait time expires before the data frame is sent, a retry counter is incremented and the random backoff value (window) is doubled. Doubling will continue until the size of the random backoff value reaches the number defined in the Maximum Contention Window. cwMax The value specified here in the Maximum Contention Window is the upper limit (in (Maximum Contention milliseconds) for the doubling of the random backoff value. This doubling continues until either the data frame is sent or the Maximum Contention Window size is Window) reached. Once the Maximum Contention Window size is reached, retries will continue until a maximum number of retries allowed is reached. TXOP Limit The TXOP Limit is a station EDCA parameter and only applies to traffic flowing from the client station to the AP. The Transmission Opportunity (TXOP) is an interval of time, in milliseconds, when a WME client station has the right to initiate transmissions onto the wireless medium (WM) towards the Unified Access Point. The TXOP Limit maximum value is 65535.
Other QoS Settings
Queue
No Acknowledgement APSD
Select On to specify that the AP should not acknowledge frames with QosNoAck as the service class value. Select On to enable Automatic Power Save Delivery (APSD), which is a power management method. APSD is recommended if VoIP phones access the network through the AP.
Note: After you configure the QoS settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low.

Configuring Email Alert
Configuring Email Alert
The Email Alert feature allows the AP to automatically send email messages when an event at or above the configured severity level occurs. Use the Email Alert Configuration page to configure mail server settings, to set the severity level that triggers alerts, and to add up to three email addresses where urgent and non‐urgent email alerts are sent. Note: Email alert is operationally disabled when the AP transitions to managed mode.
Figure 32: Configuring Email Alert Table 41: Email Alert Configuration Field Admin Mode From Address Description Globally enable or disable the Email Alert feature on the AP. By default, email alerts are disabled. Specify the email address that appears in the From field of alert messages sent from the AP, for example dlinkAP23@foo. com. The address can be a maximum of 255 characters and can contain only printable characters. By default, no address is configured. This duration, in minutes, determines how frequently the non critical messages are sent to the SMTP Server. The range is 30‐1440 minutes. The default is 30 minutes.

Configuring Email Alert
Table 41: Email Alert Configuration (Cont. ) Field Urgent Message Severity Description Configures the severity level for log messages that are considered to be urgent. Messages in this category are sent immediately. The security level you select and all higher levels are urgent: • Emergency indicates system is unusable. It is the highest level of severity. [. . . ] Walk the apVapDescription object to view the instance ID for VAP 2 (wlan0vap2). VAP 2 on Radio 1 is instance 5. Use the apVapQosMode object to set the status of VAP 2 to up (1). Use the apVapAclUp object to apply acl1 to VAP2 in the inbound direction (from the client to the AP). The ACL name is the text string, and not the ASCII code.
