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 0-15 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 0-15 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
0-15 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)
Key Type – See “Wired Equivalent Privacy (WEP)” on page 108.
4.6.1.3.1 CLI Commands for WMM
Enter 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 a policy for each access category. The wmmparms command
defines detailed WMM parameters.
To view the current 802.11g radio settings for the VAP interface, use the show
interface wireless g [0-3] command.
