Figure 58: Configuring Global and Port-related Settings for MLD Snooping
PARAMETERS
These parameters are displayed:
Global Configuration
◆
Snooping Enabled
– When enabled, the switch will monitor network traffic to determine
which hosts want to receive multicast traffic. (Default: Disabled)
This switch can passively snoop on MLD Listener Query and Report packets transferred
between IP multicast routers/switches and IP multicast host groups to identify the IP
multicast group members. It simply monitors the MLD control packets passing through it,
picks out the group registration information, and configures the multicast filters accordingly.
◆
Unregistered IPMCv6 Flooding Enabled
– Floods unregistered multicast traffic into the
attached VLAN. (Default: Enabled)
Once the table used to store multicast entries for MLD snooping is filled, no new entries
are learned. If no router port is configured in the attached VLAN, and Unregistered IPMCv6
Flooding is disabled, any subsequent multicast traffic not found in the table is dropped,
otherwise it is flooded throughout the VLAN.
◆
Leave Proxy Enabled
– Suppresses leave messages unless received from the last
member port in the group. (Default: Disabled) MLD leave proxy suppresses all
unnecessary MLD leave messages so that a non-querier switch forwards an MLD leave
packet only when the last dynamic member port leaves a multicast group.
The leave-proxy feature does not function when a switch is set as the querier. When the
switch is a non-querier, the receiving port is not the last dynamic member port in the group,
and the receiving port is not a router port, the switch will generate and send a group-
specific (GS) query to the member port which received the leave message, and then start
