Igmp-Snooping Host-Join - H3C S5120-SI Series Command Reference Manual

igmp-snooping host-join

Syntax
igmp-snooping host-join group-address [ source-ip source-address ] vlan vlan-id
undo igmp-snooping host-join group-address [ source-ip source-address ] vlan vlan-id
View
Ethernet interface view, Layer 2 aggregate interface view, port group view
Default Level
2: System level
Parameters
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.
Description
Use the igmp-snooping host-join command to configure the current port(s) as simulated member
host(s), namely configure the current port as a member host 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:
This command works on IGMP snooping–enabled VLANs. The version of IGMP on the simulated
host depends on the version of IGMP snooping running in the VLAN.
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.
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.
If configured in port group view, this feature takes effect only on those ports in this port group that
belong to the specified VLAN.
Examples
# Configure GigabitEthernet 1/0/1 as a simulated member host in VLAN 2 for multicast source 1.1.1.1
and multicast group 232.1.1.1.
