Configuring IGMP
Internet Group Management Protocol (IGMP) snooping controls multicast
traffic on a WX by forwarding packets for a multicast group only on the
ports that are connected to members of the group. IGMP is especially
useful for WLANs because bandwidth is relatively constrained. The WX
listens for multicast packets and maintains a table of multicast groups, as
well as their sources and receivers, based on the traffic. IGMP snooping is
enabled by default.
You can configure IGMP snooping parameters and enable or disable the
feature on an individual VLAN basis.
The current software version supports IGMP versions 1 and 2.
To configure IGMP snooping:
1 In the Create VLAN wizard, click VLAN IGMP Setup. The VLAN IGMP
Setup page appears.
2 To enable IGMP snooping, select Enable. To disable IGMP snooping,
clear Enable. By default, IGMP snooping is enabled.
3 In the Version list, select Version 1 or Version 2 of IGMP.
