The followingtable describes configuration sett ings availablein t he traffic managementprofile.
Parameter Description
Proportional BW
Allocation
Minimum bandwidth, as a percentage of available bandwidth, allocated to an virtual AP (VAP) when
thereis congestion on the wireless network. A VAP can use all availabl e bandwidth if no other VAPs
areactive.
Toassign 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. Specifythe percentage of bandwidth to be allocated to the VAP in the Share(%) field.
3. Click Add.
4. Repeatsteps 1-3 to assign any remaining bandwidth to additional VAPs, if desired.
Torem ovea V AP from thel istof VAPs wi thal located bandwidth, select the VAP from the Proportional
BWAll ocation field and click Delete.

DefineStation Shaping P olicy This feature hasthe follow ing three options:
ldefault-access:Traffic shaping is disabled, and cli entperformance i sdependent on MAC
contentionresolution. Thi si sthe default traffic shaping setting.
lfair-access:Each cl ient gets the same airtime, regardless of client capabi lity and capacity. This
optioni suseful in environm entsli kea traini ng facility or exam hall, where a mix of 802.11a/g,
802.11gand 802.11n clients need equal to networkresources, regardless of their capabilities. The
bw-alloc parameter of a trafficm anagement profile allows you to seta m inimum bandwidth to be
allocated toa virtual AP profil e when there is congestionon the wi relessnetwork.You m ustset
trafficshaping to fair-access to use this bandwidth allocation value for an individual virtual AP.
lpreferred-access:High-throughput (802.11n)cl ients do not get penalized because of slower
802.11a/gor 802.11btransmissions that take more air time due to lower rates. Simi larly, faster
802.11a/gclients get more access than 802.11bclients.

In the CLI
To enableand configure traffic shaping via the command-line interface, access the CLI in config mode and issue the
followingco mmands:
wlan traffic-management-profile <profile> shaping-policy fair-access|preferred-
To disable traffic shaping,use the default-access parameter:
wlan traffic-management-profile <profile> shaping-policy default-access
Use the following commands to apply an 802.11a or 8 02.11g traffic management profilet o an AP group or an
individual AP.
ap-group <name> dot11a-traffic-mgmt-profile|dot11g-traffic-mgmt-profile <profile>
ap-name <name> dot11a-traffic-mgmt-profile|dot11g-traffic-mgmt-profile <profile>
Enabling Spectrum Load Balancing
The spectrumload balancing feature helps optimize network resources by balancing clients across channels,regardless
of whethert heA P or the controlleris responding to the wireless clients' probe requests. The controlleruses the ARM
neighborupdate messages that pass between APs and the controller to determine the distribution of clients
connected to each AP's immediate (one-hop) neighbors. This feature also takes into acco unt the numberof AP s
visible to the clients in the RF neighborhood and canfacto rt heclient’s perspective on the network into it s coverage
calculations.
