Parameter Description
l aifsn: trbitrary inter-frame space number. Range: 1-15.
l ecw-max: the exponential (n) value of the maximum contention window size, as
expressed by 2
n
-1. A value of 4 computes to 2
4
-1 = 15. Range: 1-15.
l ecw-min: the exponential (n) value of the minimum contention window size, as
expressed by 2
n
-1. A value of 4 computes to 2
4
-1 = 15. Range: 0-15.
l txop: transmission opportunity, in units of 32 microseconds. Divide the desired
transmission duration by 32 to determine the value to configure. For example, for
a transmission duration of 3008 microseconds, enter 94 (3008/32). Range: 0-
2047.
l acm: this parameter specifies mandatory admission control. With a value of 1, the
client reserves the access category through traffic specification (TSPEC) signaling.
A value of 0 disables this option.
5. Click Apply.
Using the CLI to configure EDCA parameters
Use the following commands:
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>
Enabling WMM Queue Content Enforcement
WMM queue content enforcement is a firewall setting that you can enable to ensure that the voice priority is
used for voice traffic. When you enable this feature, 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 used to reserve bandwidth, then TSPEC signaling informs the client that the reservation
is terminated.
You can use the WebUI or CLI to enable WMM queue content 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.
In the CLI
Use the following command:
firewall wmm-voip-content-enforcement
Unified Communication and Collaboration
This section describes the Unified Communication and Collaboration (UCC)feature. The Unified
Communications Manager (UCM) is the core solution component of this feature. UCC addresses the onslaught
of mobile devices that use voice, video, and collaboration applications. UCC solution reduces the cost of
infrastructure for enterprise communication and collaboration.
