Configuring static ports
If all hosts attached to a port are interested in the multicast data addressed to a particular multicast group
or the multicast data that a particular multicast source sends to a particular group, you can configure the
port as a static member port for the specified multicast group or the specified multicast source and group.
You can also configure a port to be a static router port, through which the router can forward all the
multicast traffic that it received.
Configuration guidelines
• A static member port does not respond to queries from the IGMP querier. When you configure a
port as a static member port or cancel this configuration on the port, the port does not unsolicitedly
send any IGMP report or an IGMP leave message.
• Static member ports and static router ports never age out. To remove such a port, use the
corresponding undo command.
Configuration procedure
To configure static ports:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 2 Ethernet

aggregate interface view, or
enter port group view.
• Enter Layer 2 Ethernet interface

Use either command.
3. Configure the port as a static
member port.
igmp-snooping static-group
group-address [ source-ip
source-address ] vlan vlan-id
No static member ports exist by
default.
4. Configure the port as a static
router port.
igmp-snooping static-router-port
vlan vlan-id
No static router ports exist by
default.
Configuring a port as a simulated member host
Generally, a host that runs IGMP can respond to IGMP queries. If a host fails to respond, the multicast
router might deem that no member of this multicast group exists on the subnet, and removes the
corresponding forwarding path.
To avoid this situation, you can configure the port as a simulated member host for a multicast group.
When the simulated member host receives an IGMP query, it gives a response. Therefore, the router can
continue receiving multicast data.
A simulated host is equivalent to an independent host in the following ways:
• When a port is configured as a simulated member host, the router sends an unsolicited IGMP report
through the port, and responds to IGMP general queries with IGMP reports through the port.
