Port Related Configuration
•
Port
- The switch port number of the port.
•
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.
•
Fast Leave
-
Enable the fast leave on the port. The system will remove the group record and
stop forwarding data upon receiving the IGMPv2 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.
•
Max multicast groups (Throttling)
- Enable to limit the number of multicast groups to which a
switch port can belong, ranging from 1,2,3…10, unlimited.
