Usage Scenario
When the command is used to clear the dynamic forwarding entries in a certain VLAN/VSI, the multicast traffic received by hosts in the VLAN/VSI is interrupted until the hosts send IGMP Report messages again. After receiving the IGMP Report messages, the Router regenerates the forwarding entries and the hosts start to receive the multicast traffic again.
If the VLAN is bound to a VSI, the system does not prompt error information when the reset igmp-snooping group vlan all command is run.
