DGS-1510-28XMP/ME:admin# show mld_snooping static_group
VLAN ID/Name

DGS-1510-28XMP/ME:admin#
45-15 config mld_snooping data_driven_learning
Description
This command is used to enable or disable the data-driven learning of an MLD snooping group.
When data-driven learning is enabled for the VLAN, when the Switch receives the IP multicast traffic, on this VLAN,
an MLD snooping group will be created. That is, the learning of an entry is not activated by MLD membership
registration, but activated by the traffic. For an ordinary MLD snooping entry, the MLD protocol will take care 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 the 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 MLD member ports are learned later, the entry will become an
ordinary MLD snooping entry. That is, the aging out mechanism will follow the ordinary MLD snooping entry.
