ProSAFE Dual-Band Wireless AC Access Points WAC720 and WAC730
Setting Description
Max. Burst Enter the maximum burst value that specifies the maximum burst length (in microseconds)
allowed for packet bursts on the wireless network. A packet burst is a collection of multiple
frames transmitted without header information. Decreasing this value increases the priority
of the queue. Valid values for maximum burst length are all multiples of 32 between 0 and
8192, inclusive of 0 and 8192.
The default values are Data 0: 0; Data 1: 0; Data 2: 3008; Data 3: 1504.
Station EDCA parameters
AIFS Enter the Arbitration Inter-Frame Spacing (AIFS) interval that specifies the wait time (in
milliseconds) between data frames. A higher AIFS value means a higher priority for a
queue. Valid values for AIFS are 0 through 8.
The default values are Data 0: 3; Data 1: 7; Data 2: 2; Data 3: 2.
cwMin Enter the minimum contention window (cwMin) value that specifies the upper limit (in
milliseconds) of a range from which the initial random back-off wait time is determined.
Decreasing this value increases the priority of the queue. The value for cwMin must be
lower than the value for cwMax. Valid values are 0, 1, 3, 7, 15, 31, 63, 127, 255, 511, and
1023.
The default values are Data 0: 15; Data 1: 15; Data 2: 7; Data 3: 3.
cwMax Enter the maximum contention window (cwMax) value that specifies the upper limit (in
milliseconds) for the doubling of the random back-off value. Decreasing this value
increases the priority of the queue. The value for cwMax must be higher than the value for
cwMin. Valid values are 0, 1, 3, 7, 15, 31, 63, 127, 255, 511, and 1023.
The default values are Data 0: 1023; Data 1: 1023; Data 2: 15; Data 3: 7.
TXOP Limit Enter the transmission opportunity (TXOP) value that specifies the time interval (in
microseconds) in which a client station can initiate transmissions on the wireless medium
(WM). Decreasing this value increases the priority of the queue. Valid values for TXOP
Limit are all multiples of 32 between 0 and 8192, inclusive of 0 and 8192.
The default values are Data 0: 0; Data 1: 0; Data 2: 3008; Data 3: 1504.

Configure and Manage Quality of Service Policies

The wireless access point lets you configure and apply QoS policies to wireless clients. In
each QoS policy, you can specify multiple classifications (match clauses) and apply traffic to
eight priority queues based on the following information in the Layer 2, Layer 3, Layer 3 IP
headers, and Layer 4:
• IP precedence. Indicates the IP Type of Service (ToS) or precedence in the IP headers.
• IP DSCP. Indicates the Differentiated Services Code Point (DSCP) marking in the IP
header.
• IP protocol 119. Indicates the IP protocol field in the IP header with value 119.
• 802.1P. Indicates the 3-bit Class of Service (CoS) field in the class header.
