Chapter 9 Configuring QoS
Configuring QoS
Using the Admission Control check boxes, you can control client use of the access categories. When you
enable admission control for an access category, clients associated to the access point must complete the
WMM admission control procedure before they can use that access category. However, access points do
not support the admission control procedure in this release, so clients cannot use the access category
when you enable Admission Control.
Disabling IGMP Snooping Helper
When Internet Group Membership Protocol (IGMP) snooping is enabled on a switch and a client roams
from one access point to another, the clients’ multicast session is dropped. When the access points’
IGMP snooping helper is enabled, the access point sends a general query to the wireless LAN, prompting
the client to send in an IGMP membership report. When the network infrastructure receives the host’s
IGMP membership report, it ensures delivery of that host’s multicast data stream.
The IGMP snooping helper is enabled by default. To disable it, browse to the QoS Policies - Advanced
page, select Disable, and click Apply.
