Item Description
Drop Unknown
Enable or disable the function of dropping unknown multicast packets.
Unknown multicast data refers to multicast data for which no entries exist in the
IGMP snooping forwarding table.
•
With the function of dropping unknown multicast data enabled, the device
drops all the received unknown multicast data.
•
With the function of dropping unknown multicast data disabled, the device
floods unknown multicast data in the VLAN to which the unknown multicast
data belong.
Querier
Enable or disable the IGMP snooping querier function.
On an IP multicast network that runs IGMP, a Layer 3 device acts as an IGMP
querier to send IGMP queries and establish and maintain multicast forwarding
entries for correct multicast traffic forwarding at the network layer.
On a network without Layer 3 multicast devices, no IGMP querier-related
function can be implemented because a Layer 2 device does not support
IGMP. To implement IGMP querier-related function, you can enable IGMP
snooping querier on a Layer 2 device so that the device can generate and
maintain multicast forwarding entries at data link layer.
Query interval
Configure the IGMP query interval.
General Query Source IP
Source IP address of IGMP general queries.
Special Query Source IP
Source IP address of IGMP group-specific queries.
