A static member port does not respond to queries from the MLD querier; when you configure a port as a static member port or cancel this configuration on the port, the port does not send an unsolicited MLD report or an MLD done message. Static member ports and static router ports never age out. To remove such a port, you use the corresponding undo command. To configure static ports: Step 1. Enter system view. 2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view. Command system-view interface interface-type interface-number Remarks N/A Use either command. 3. Configure the port as a static mld-snooping static-group member port. ipv6-group-address [ source-ip ipv6-source-address ] vlan vlan-id 4. Configure the port as a static mld-snooping static-router-port router port. vlan vlan-id No static member ports exist by default. No static router ports exist by default. Configuring a port as a simulated member host Generally, a host that runs MLD can respond to MLD queries. If a host fails to respond, the multicast router might deem that the IPv6 multicast group has no members on the subnet, and removes the corresponding forwarding path. To avoid this situation, you can configure a port on the switch as a simulated member host for an IPv6 multicast group. A simulated host is equivalent to an independent host. For example, when a simulated member host receives an MLD query, it gives a response separately. Therefore, the switch can continue receiving IPv6 multicast 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 MLD report through the port, and can respond to MLD general queries with MLD reports through the port. • When the simulated joining configuration is canceled on the port, the switch sends an MLD done message through that port. To configure a port as a simulated member host: Step 1. Enter system view. 2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view. 3. Configure the port as a simulated member host. Command system-view Remarks N/A interface interface-type interface-number Use either command. mld-snooping host-join ipv6-group-address [ source-ip ipv6-source-address ] vlan vlan-id Not configured by default. 215
