config igmp_snooping data_driven_learning
Description
This command is used to enable or disable the data driven learning of an IGMP snooping group.
When data-driven learning is enabled for the VLAN, when the Switch receives the IP multicast traffic on this VLAN,
an IGMP snooping group will be created. That is, the learning of an entry is not activated by IGMP membership
registration, but activated by the traffic. For an ordinary IGMP snooping entry, the IGMP protocol will take care of
the aging out of the entry. For a data-driven entry, the entry can be specified not to be aged out or to be aged out
by the aged timer.
When data driven learning is enabled, and the data driven table is not full, the multicast filtering mode for all ports
is ignored. That is, the multicast packets will be forwarded to router ports. If the data driven learning table is full, the
multicast packets will be forwarded according to the multicast filtering mode.
Note that if a data-driven group is created and IGMP member ports are learned later, the entry will become an
ordinary IGMP snooping entry. That is, the aging out mechanism will follow the ordinary IGMP snooping entry.
Format
