WMM prioritizes traffic according to four Access Categories (AC) - voice, video, best effort, and background. However, it does not provide guaranteed throughput. Packets with QoS header including Diffserv/IP ToS and 802.1p will be mapped into 4 Access Categories of WMM, packets without QoS header will be assigned to the Best Effort queue. Please refer to the table below for mapping from 802.1p and ToS mapping to WMM: Queue AC_BK AC_BE AC_VI AC_VO Data Transmitted Clients to AP Background. Best Effort Video Voice IP ToS 802.1P Priority Priority Description 0x08 0x20 1, 2 High throughput. Bulk data that requires maximum Low throughput and is not time-sensitive is sent to this queue (FTP data, for example). 0, 3 Medium Medium throughput and delay. Most traditional IP data is sent to this queue 0x28 0xa0 4, 5 High Minimum delay. Time-sensitive video data is automatically sent to this queue 0x30 0xe0 0x88 6, 7 0xb8 High Time-sensitive data like VoIP and streaming media are automatically sent to this queue „ Security Type : Option is "Disabled", "WEP" or "AES" from drop-down list. Needs the same type to build WDS links. Security type takes effect when WDS is enabled. Î WEP Key : Enter HEX or ASCII WEP key at different length as shown below. This system supports up to 4 sets of WEP keys. 9 Key Length : The available options are 64 bits, 128 bits or 152 bits. 9 WEP auth Method : Enable the desired option among Open system and Shared. 9 Key Index : key index is used to designate the WEP key during data transmission. 4 different WEP keys can be entered at the same time, but only one is chosen. 9 WEP Key # : Enter HEX or ASCII format WEP key value; the system supports up to 4 sets of WEP keys. 34
