Using The Cli To Configure Wmm - Enterasys RoamAbout RBT-4102 Configuration Manual

– Support: WMM will be used for any associated device that supports this feature. Devices
that do not support this feature may still associate with the access point.
– Required: WMM must be supported on any device trying to associated with the access
point. Devices that do not support this feature will not be allowed to associate with the
access point.
• WMM BSS Parameters – These parameters apply to the wireless clients.
• WMM AP Parameters – These parameters apply to the access point.
– logCWMin (Minimum Contention Window) – The initial upper limit of the random
backoff wait time before wireless medium access can be attempted. The initial wait time is
a random value between zero and the CWMin value. Specify the CWMin value in the
range 1‐15 microseconds. Note that the CWMin value must be equal or less than the
CWMax value.
– logCWMax (Maximum Contention Window) – The maximum upper limit of the random
backoff wait time before wireless medium access can be attempted. The contention
window is doubled after each detected collision up to the CWMax value. Specify the
CWMax value in the range 1‐15 microseconds. Note that the CWMax value must be
greater or equal to the CWMin value.
– AIFS (Arbitration Inter‐Frame Space) – The minimum amount of wait time before the next
data transmission attempt. Specify the AIFS value in the range 1‐15 microseconds.
– TXOP Limit (Transmit Opportunity Limit) – The maximum time an AC transmit queue
has access to the wireless medium. When an AC queue is granted a transmit opportunity,
it can transmit data for a time up to the TxOpLimit. This data bursting greatly improves
the efficiency for high data‐rate traffic. Specify a value in the range 0‐65535 microseconds.
– Admission Control – The admission control mode for the access category. When enabled,
clients are blocked from using the access category. (Default: Disabled)

Using the CLI to Configure WMM

Enter the interface wireless mode, and type wmm required for clients that want to associate with
the access point. The wmm‐acknowledge‐policy command is used to enable or disable the
acknowledge policy for each access category. The wmmparms command defines detailed WMM
parameters.
Examples
