Usage Guidelines
Usage Scenario
When multicast groups on interfaces change, the system generates new Layer 2 multicast forwarding entries until the aging time of multicast member interfaces expire. To enable the system to generate new multicast forwarding entries immediately, use the reset igmp-snooping group command to clear old multicast forwarding entries.
Precautions
If the command clears the dynamic forwarding entries of a VSI, the hosts in the VSI cannot receive multicast packets.
This command cannot clear static multicast forwarding entries.
