26Configuration guidelines• A static member port does not respond to queries from the IGMP querier; when you configure a portas a static member port or cancel this configuration on the port, the port does not send anunsolicited IGMP report or an IGMP leave message.• Static member ports and static router ports never age out. To remove such a port, use thecorresponding undo command.Configuration procedureTo configure static ports:Step Command Remarks1. Enter system view. system-view N/A2.

If a host failsto respond, the multicast router might deem that no member of this multicast group exists on the networksegment, and removes the corresponding forwarding path.To avoid this situation, you can configure the port as a simulated member host for a multicast group. Asimulated host is equivalent to an independent host. For example, when a simulated member hostreceives an IGMP query, it gives a response separately. Therefore, the switch can continue receivingmulticast data.A simulated host acts like a real host in the following ways:• When a port is configured as a simulated member host, the switch sends an unsolicited IGMPreport through the port, and can respond to IGMP general queries with IGMP reports through theport.• When the simulated joining function is disabled on a port, the switch sends an IGMP leavemessage through the port.
