Switch Management> MLD Snooping > Global Setting page is used to configure the switch to forward multicast traffic
intelligently.
◆MLD Snooping Status – When enabled, the switch will monitor network traffic to determine which hosts want to receive
multicast traffic.
◆Querier Status – When enabled, the switch can serve as the querier for MLDv2 snooping if elected. The querier is
(Default: Disabled)
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
◆Robustness – MLD Snooping robustness variable. A port will be removed from the receiver list for a multicast service when
started if it detects an IPv6 multicast router on the network.
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.
◆Query Interval – The interval between sending MLD general queries.
(Range: 2-10 Default: 2)
(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
◆Query Max Response Time – The maximum response time advertised in MLD general queries.
the multicast groups they have joined.
(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
◆Router Port Expiry Time – The time the switch waits after the previous querier stops before it considers the router port (i.e.,
the last member.
the interface that had been receiving query packets) to have expired.
(Range: 300-500 seconds; Default: 300 seconds)
