19.3 IGMP Port Settings
Router Port
Specify which ports act as router ports. A router port is a port on the Ethernet switch that leads towards the Layer 3
multicast device or IGMP querier.
If an aggregation member port is selected as a router port, the whole aggregation will act as a router port.
Unregistered IPMCv4 Flooding enabled
Enable unregistered IPMCv4 traffic flooding.
The flooding control takes effect only when IGMP Snooping is enabled.
When IGMP Snooping is disabled, unregistered IPMCv4 traffic flooding is always active in spite of this setting.
Fast Leave
Enable the fast leave on the port.
System will remove group record and stop forwarding data upon receiving the leave message without sending last
member query messages.
It is recommended to enable this feature only when a single IGMPv2 host is connected to the specific port.
19.4 Save Changes to Startup Configuration
All changes must be saved to startup configuration or they will be lost after power cycle. To save
changes navigate to Maintenance>Configuration>Save Sartup Config as shown below in Figure 15.
