Setting the SSH Status
Setting the SSH Status
Secure Shell (SSH) is a program that provides access to the DWL‐x600AP CLI from a remote host. SSH is more secure than Telnet for remote access because it provides strong authentication and secure communications over insecure channels. From the SSH page, you can enable or disable SSH access to the system.
Figure 29: SSH Status Table 38: SSH Settings Field SSH Status Description Choose to either enable or disable SSH access to the AP CLI: • To permit remote access to the AP by using SSH, click Enabled. • To prevent remote access to the AP by using SSH, click Disabled.
Setting the Telnet Status
Telnet is a program that provides access to the DWL‐x600AP CLI from a remote host. From the Telnet page, you can enable or disable Telnet access to the system.
Figure 30: Telnet Status Table 39: Telnet Settings Field Telnet Status Description Choose to either enable or disable Telnet access to the AP CLI: • To permit remote access to the AP by using Telnet, click Enabled. • To prevent remote access to the AP by using Telnet, click Disabled.

Configuring Quality of Service
Configuring Quality of Service
Quality of Service (QoS) provides you with the ability to specify parameters on multiple queues for increased throughput and better performance of differentiated wireless traffic like Voice‐over‐IP (VoIP), other types of audio, video, and streaming media, as well as traditional IP data over the UAP. Configuring QoS on the UAP consists of setting parameters on existing queues for different types of wireless traffic, and effectively specifying minimum and maximum wait times (through Contention Windows) for transmission. The settings described here apply to data transmission behavior on the AP only, not to that of the client stations. AP Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the AP to the client station. Station Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the client station to the AP. The default values for the AP and station EDCA parameters are those suggested by the Wi‐Fi Alliance in the WMM specification. In normal use these values should not need to be changed. Changing these values will affect the QoS provided. Note: On the DWL‐6600AP and DWL‐8600AP, the QoS settings apply to both radios, but the traffic for each radio is queued independently. To set up queues for QoS, click the QoS tab under the Services heading and configure settings as described in Table 40 on page 103.

AP EDCA Parameters
Description Possible options are: Custom, Default, Optimized for Voice. Queues are defined for different types of data transmitted from AP‐to‐station: • Data 0 (Voice) — High priority queue, minimum delay. Time‐sensitive data such as VoIP and streaming media are automatically sent to this queue. • Data 1(Video) — High 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). The Arbitration Inter‐Frame Spacing (AIFS) specifies a wait time for data frames. The wait time is measured in slots. Valid values for AIFS are 1 through 255.

Table 40: QoS Settings (Cont. ) Field Description
cwMin This parameter is input to the algorithm that determines the initial random backoff (Minimum Contention wait time (window) for retry of a transmission. Window) The value specified for Minimum Contention Window is the upper limit (in milliseconds) of a range from which the initial random backoff wait time is 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. Valid values for cwMin are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for cwMin must be lower than the value for cwMax. 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.
