Each Virtual AP (VAP) port is similar to a Layer 2 switch port. With IGMP Snooping enabled in
the AP, clients associated to a VAP will only receive multicast packets if there is at least one client
joined the multicast group in that VAP. Unlike ordinary IGMP Snooping implementation, where
Layer 2 switch converts multicast to unicast and delivers them to devices registered with the
multicast group, AP should simply send out the multicast packets from the VAP which has at least
one client joined the multicast group. This is done because the wireless media is a broadcast media.
It does not need to be sent multiple times when there are more than one registered clients.
When IGMP Snooping is turned on, multicast packets should be dropped at the VAP exit if there is
no client from the VAP who has joined the corresponding multicast group.
The IGMP snooping forwarding table (port and multicast MAC address mapping table) should
support aging mechanism to age out the entry which has no multicast traffic for a period of time
(120 seconds in AP-100).
The default setting of the IGMP Snooping is “Disabled”.
Multicast Traffic：Default setting is "Enabled ". If set to "Enabled", the system allows multicast
traffic in all VAPs. If set to "Disabled", all multicast traffic in all VAPs will be dropped.
Enable Optimization Mode：Set the Optimization mode to optimize the performance depending
on different deployment environment.
Optimization Mode：There are three modes, default, optimized for throughput and optimized for
capacity.
Data Rate Setting
Data Rate：Default setting is “best”. The transmission data rate that appears on the drop-down
AP-100 supports “Multicast Traffic Data Rate Setting” to transmit all multicast traffic of the 2.4G
interface at the configured multicast data rate. The multicast data rate must be set to any of the basic
data rates. Default setting is 1 Mbps.
AirFi Setting
AirFi Mode：Enable AirFi mode to get enhanced throughput experience.
AirFi Level：There are four options for AirFi level: Level I, Level II, Level III and Custom. AirFi
level I is recommended.
Advanced configuration procedures：
1. Select Configuration->Wireless->Radio0(2.4G)->Advanced
2. AMPDU selected by default
3. AMSDU selected by default
4. Data Rate by default it is “best”
