2: System level 

group-address: Address of the multicast group that the simulated host is to join, in the range of 

224.0.1.0 to 239.255.255.255.  

source-address: Address of the multicast source that the simulated host is to join. The value of this 

argument should be a valid unicast address or 0.0.0.0. If the value is 0.0.0.0, this means that no 

multicast source is specified.  

vlan vlan-id: Specifies the VLAN that comprises the port(s), where vlan-id is in the range of 1 to 4094.  

Use the igmp-snooping host-join command to configure the current port(s) as simulated member 

host(s) for the specified multicast group or source and group.  

Use the undo igmp-snooping host-join command to remove the current port(s) as simulated member 

host(s) for the specified multicast group or source and group.  

By default, this function is disabled.  

Note that:  

z 

This command works on both IGMP Snooping–enabled VLANs and VLANs with IGMP enabled on 

their VLAN interfaces. The version of IGMP on the simulated host depends on the version of IGMP 

Snooping running in the VLAN or the version of IGMP running on the VLAN interface.  

z 

The source-ip  source-address option in the command is meaningful only for IGMP Snooping 

version 3. If IGMP Snooping version 2 is running, although you can include source-ip 

source-address in the command, the simulated host does not respond to a query message.  

z 

If configured in Ethernet interface view or Layer 2 aggregate interface view, this feature takes effect 

only if the interface belongs to the specified VLAN.
