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) 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.
