Enabled
periodically check the multicast group for members that are no longer active.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.
#Notice:
Add a new VLAN group, the VLAN ID will be added to the table automatically with both “IGMP
Snooping Enabled” and “IGMP Querying Enabled”.
