Parameter Description
lecw-max: The exponential (n)value of the maximum contentionwi ndow size, as expressedby
2n-1.A value of 4 com putesto 24-1 = 15. Possible values are 1-15.
lecw-min: The exponential (n) value of them inimum contention window size, as expressed by
2n-1.A value of 4 com putesto 24-1 = 15. Possible values are 0-15.
ltxop:Transmission opportunity, in units of 32 microseconds. Divide the desired transmission
durationby 32 to determine the value to configure. For example, for a transmission duration of
3008microseconds, enter 94 (3008/32).Possible values are 0-2047.
lacm: This parameter specifies mandatory admission control. W ith a value of 1, the client
reservesthe access category throughtraffic specification (TSPEC) signali ng. A value of0
disablesthis option.
Voice Setthe followi ng parameters todefine the background queue.
laifsn:Arbitrary inter-frame space number. Possible values are 1-15.

Using the CLI to configureEDCA parameters

wlan edca-parameters-profile {ap|station} <profile>
{background | best-effort | video | voice}
[acm][aifsn <number>] [ecw-max <exponent> [ecw-min <exponent>] [txop <number>]

To associate the EDCA profile instance to a SSID profile:

wlan ssid-profile <profile>
edca-parameters-profile {ap|sta} <profile>
EnablingWMM Queue Content Enforcement

WMMqueue content enforcement is a firewall setting that you can enable to ensure that the voice priority is used

for voice traffic. Whenthis feature is enabled, if traffic to or from the user is inconsistent with the associated QoS

policy for voice, the traffic is reclassified to best effort and data path counters incremented. If TSPEC admission

were usedt o reservebandwidth, then TSPEC signaling is used to i nformthe client that the reservation is

terminated.

You can uset heWebUI o rCLI to enable WMM queuecontent enforcement.

In the WebUI

1. Navigate to the Configuration > Advanced Services > Stateful Firewall page.

2. Select Enforce WMM Voice Priority Matches Flow Content.

3. Click Apply.
