ROUP ONFIGURATION
Normally, an IGMP host responds to IGMP query messages of the multicast router. In
case of response failure, the multicast router may consider that there is no multicast
member on this network segment and cancel the corresponding path.
To avoid such a problem, you can configure an interface of the switch as a multicast
group member. When the interface receives IGMP query packets, it will respond, thus
ensuring that the network segment of the interface can normally receive multicast
packets.

By default, a routing port does not join any multicast group. Note that the Ethernet
port must belong to the VLAN; otherwise, your configuration cannot take effect.
