Item Description
IGMP snooping
Enable or disable IGMP snooping in the VLAN.
You can proceed with the subsequent configurations only if
Enable
is selected
here.
Version
By configuring an IGMP snooping version, you actually configure the versions of
IGMP messages that IGMP snooping can process.
•
IGMPv2 snooping can process IGMPv1 and IGMPv2 messages, but it floods
IGMPv3 messages in the VLAN instead of processing them.
•
IGMPv3 snooping can process IGMPv1, IGMPv2, and IGMPv3 messages.
IMPORTANT:
If you change the IGMPv3 snooping to IGMPv2 snooping, the system clears all
IGMP snooping forwarding entries that are dynamically added.
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.
•
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.
