IGMP Snooping Modes
You can configure active or passive IGMP modes on the RUCKUS device. The default mode is passive. If you specify an IGMP mode for a VLAN, it overrides the global setting.
- Active: When active IGMP mode is enabled, a RUCKUS device actively sends out IGMP queries to identify multicast groups on the network, and makes entries in the IGMP table based on the group membership reports it receives.
Note: Routers in the network generally handle this
operation. Use the active IGMP mode only when the device is in a standalone Layer
2
switched network with no external IP multicast router attachments. In this case,
enable
the active IGMP mode on only one of the devices and leave the other devices configured
for passive IGMP mode.
