Example
To display all the MLD snooping static groups:
DGS-3120-24TC:admin# show mld_snooping static_group
VLAN ID/Name
-------------- ------------------
1 / default
Total Entries : 1
DGS-3120-24TC:admin#
63-15 config mld_snooping data_driven_learning (EI and SI Mode
Only)
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.
Format
