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:
z 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.
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.
z 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.
