Use the Multicast > MLD Snooping > General page to configure the switch to forward multicast traffic intelligently. Based on the MLD query and report messages, the switch forwards multicast traffic only to the ports that request it. This prevents the switch from broadcasting the traffic to all ports and possibly disrupting network performance.
When enabled, the switch will monitor network traffic to determine which hosts want to receive multicast traffic. (Default: Disabled)
When enabled, the switch can serve as the querier for MLDv2 snooping if elected. The querier is responsible for asking hosts if they want to receive multicast traffic. (Default: Disabled)
An IPv6 address must be configured on the VLAN interface from which the querier will act if elected. When serving as the querier, the switch uses this IPv6 address as the query source address.
The querier will not start or will disable itself after having started if it detects an IPv6 multicast router on the network.
MLD Snooping robustness variable. A port will be removed from the receiver list for a multicast service when no MLD reports are detected in response to a number of MLD queries. The robustness variable sets the number of queries on ports for which there is no report. (Range: 2-10 Default: 2)
The interval between sending MLD general queries. (Range: 60-125 seconds; Default: 125 seconds)
This attribute applies when the switch is serving as the querier.
An MLD general query message is sent by the switch at the interval specified by this attribute. When this message is received by downstream hosts, all receivers build an MLD report for the multicast groups they have joined.
The maximum response time advertised in MLD general queries. (Range: 5-25 seconds; Default: 10 seconds)
This attribute controls how long the host has to respond to an MLD Query message before the switch deletes the group if it is the last member.
The time the switch waits after the previous querier stops before it considers the router port (i.e., the interface that had been receiving query packets) to have expired. (Range: 300-500 seconds; Default: 300 seconds)
The protocol version used for compatibility with other devices on the network. This is the MLD version the switch uses to send snooping reports. (Range: 1-2; Default: 2)
The action for dealing with unknown multicast packets. Options include:
Floods any received IPv6 multicast packets that have not been requested by a host to all ports in the VLAN.
Forwards any received IPv6 multicast packets that have not been requested by a host to ports that are connected to a detected multicast router. (This is the default action.)
