Parameter Description
Station
Shaping Policy
Define Station Shaping Policy This feature has the following three options:
l default-access: Traffic shaping is disabled, and client performance is dependent on
MAC contention resolution. This is the default traffic shaping setting.
l fair-access: Each client gets the same airtime, regardless of client capability and
capacity. This option is useful in environments like a training facility or exam hall,
where a mix of 802.11a/g, 802.11g, and 802.11n clients need equal to network
resources, regardless of their capabilities. The bw-alloc parameter of a traffic
management profile allows you to set a minimum bandwidth to be allocated to a
virtual AP profile when there is congestion on the wireless network. You must set
traffic shaping to fair-access to use this bandwidth allocation value for an individual
virtual AP.
l preferred-access: High-throughput (802.11n) clients do not get penalized because
of slower 802.11a/g or 802.11b transmissions that take more air time due to lower
rates. Similarly, faster 802.11a/g clients get more access than 802.11b clients.
Proportional
BW Allocation
You can allocate a maximum bandwidth, as a percentage of available bandwidth to a
virtual AP (VAP).
To assign a percentage of bandwidth to a virtual AP:
1. Click the Virtual AP drop-down list, and select the VAP to which you would like to
allocate a bandwidth share.
2. Specify the percentage of bandwidth to be allocated to the VAP in the Share(%) field.
3. Select the Hard Limit checkbox to restrict the bandwidth for the VAP. Do not select
the Hard Limit checkbox if you want to restrict the bandwidth for this VAP when there
is a congestion on the wireless network.
4. Click Add.
5. Repeat steps 1-4 to assign any remaining bandwidth to additional VAPs, if desired.
To remove a VAP from the list of VAPs with allocated bandwidth, select the VAP from the
Proportional BW Allocation field and click Delete.
Report Interval Number of minutes between bandwidth usage reports.
Range: 1-99 minutes
Default value is 5 minutes.
Table 104: Traffic Management Profile Parameters
In the CLI
To enable and configure traffic shaping via the command-line interface, access the CLI in config mode and issue
the following commands:
wlan traffic-management-profile <profile> shaping-policy default-access|fair-access|preferred-
access
Use the following commands to apply an 802.11a or 802.11g traffic management profile to an AP group or an
individual AP.
ap-group <name> dot11a-traffic-mgmt-profile|dot11g-traffic-mgmt-profile <profile>
Enabling or Disabling the Hard Limit Parameter in Traffic Management Profile
You can configure the limit on OTA bandwidth for a virtual AP by enabling or disabling the hard-limit parameter
in the Traffic management profile.
