the VLAN. The Query mode is used to

periodically check the multicast group for members that are no longer active. In the

case where there is more than one multicast router on a sub network, one router is

elected as the ‘queried’. This router then keeps track of the membership of the

multicast groups that have active members. The information received from IGMP is

then used to determine if multicast packets should be forwarded to a given sub

network or not. The router can check, using IGMP, to see if there is at least one

member of a multicast group on a given subnet work. If there are no members on a

sub network, packets will not be forwarded to that sub network.

Enabled is the default value.

Add a new VLAN group, the VLAN ID will be added to the table automatically with both “IGMP

Snooping Enabled” and “IGMP Querying Enabled”.
