MLD Snooping
– 678 –
Command Usage
â—† If enabled, the switch will serve as querier if elected. The querier is responsible
for asking hosts if they want to receive multicast traffic.
â—† 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 its own
IPv6 address as the query source address.
â—† The querier will not start or will disable itself after having started if it detects an
IPv6 multicast router on the network.
Example
Console(config)#ipv6 mld snooping querier
Console(config)#
ipv6 mld snooping
query-interval
This command configures the interval between sending MLD general queries. Use
the no form to restore the default.

Command Usage
â—† This command applies when the switch is serving as the querier.
â—† An MLD general query message is sent by the switch at the interval specified by
this command. When this message is received by downstream hosts, all
receivers build an MLD report for the multicast groups they have joined.
Example
Console(config)#ipv6 mld snooping query-interval 150
