QoS Commands
qos sta-params
This command configures QoS related parameters on the device for the
wireless stations.
Syntax
qos sta-params <voice|video|best-effort|background> {<[aifs <aifs>] [cwmin
<cwmin>] [cwmax <cwmax>] [txop-limit <txop-limit>]}
• voice - High priority queue, minimum delay. Time-sensitive data such
as VoIP and streaming media are automatically sent to this queue.
• video - High priority queue, minimum delay. Time-sensitive video data
is automatically sent to this queue.
• best effort - Medium priority queue, medium throughput and delay.
Most traditional IP data is sent to this queue.
• 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 <aifs>] - Arbitration Inter-Frame Spacing (AIFS) specifies a wait
time in milliseconds for data frames. Valid values are: 1-255.
• [cwmin <cwmin>] - Specifies the Minimum Contention Window QoS
parameter. The value specified is the lower limit (in milliseconds) of
a range from which the initial random backoff wait time is deter-
mined. Valid values for the "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 <cwmax>] - Specifies the Maximum Contention Window QoS
parameter. The value specified is the upper limit (in milliseconds) of
a range from which the initial random backoff wait time is deter-
mined. Valid values for the "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".
• [txop-limit <txop-limit] - Specifies the Transmission Opportunity Limit
QoS parameter. This value specifies (in milliseconds) the Transmis-
sion Opportunity (TXOP) for client stations; that is, the interval of
time when a WMM client station has the right to initiate transmissions
on the wireless network. Valid values are 0.0 through 65535.
Default Setting: See tabled output.
