Description
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.
•
If the function of dropping unknown multicast data is enabled, the switch
forwards the unknown multicast packets to the router ports instead of flooding
them in the VLAN. If the switch does not have a router port, it drops the
unknown multicast packets.
•
If the function of dropping unknown multicast data is disabled, the switch
floods the unknown multicast data in the VLAN to which the unknown multicast
data belong.
Enable or disable the IGMP snooping querier function.
In an IP multicast network that runs IGMP, a Layer 3 device is elected as the IGMP
querier to send IGMP queries, so that all Layer 3 multicast devices can 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
address this issue, 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 for correct multicast traffic forwarding at data link layer.
