Configuring MLD Snooping Querier

Use this page to configure the global MLD snooping querier settings on the device. MLD snooping requires that one central switch or router periodically query all end-devices on the network to announce their multicast memberships. This central device is the MLD querier. When Layer 3 IP multicast routing protocols are enabled in a network with IP multicast routing, the IP multicast router acts as the MLD querier. However, if the IP-multicast traffic in a VLAN needs to be Layer 2 switched only, an IP-multicast router is not required. The MLD snooping querier can perform the MLD snooping functions on the VLAN.

Note

This feature is available for 220 switches only.
