Figure 217 Information about an IGMP snooping multicast entry
Description
Configure the maximum number of multicast groups that the port can join.
With this feature, you can regulate multicast traffic on the port.
IMPORTANT:
When the number of multicast groups a port has joined reaches the configured threshold, the
system deletes all the forwarding entries persistent on that port from the IGMP snooping
forwarding table, and the hosts on this port need to join the multicast groups again.
Enable or disable the fast leave function for the port.
With the fast leave function enabled on a port, the switch, when receiving an IGMP leave
message on the port, immediately deletes that port from the outgoing port list of the
corresponding forwarding table entry. Then, when receiving IGMP group-specific queries
for that multicast group, the switch does not forward them to that port. In VLANs where
only one host is attached to each port, the fast leave function helps improve bandwidth
and resource usage.
IMPORTANT:
If fast leave is enabled for a port to which more than one host is attached, when one host
leaves a multicast group, the other hosts listening to the same multicast group fails to receive
multicast data.
