H3C S7500E Series Ethernet Switches Chapter 1 IGMP Snooping Configuration Commands
1-22
Parameters
group-address: Address of the multicast group to be statically joined, in the range of
224.0.0.0 to 239.255.255.255.
source-address: Address of multicast source to be statically joined. 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 no multicast source is specified.
vlan vlan-id: Specifies the VLAN that comprises the Ethernet port(s), where vlan-id is in
the range of 1 to 4094.
Description
Use the igmp-snooping static-group command to enable the static (*, G) or (S, G)
joining function, namely to configure the current port or port group as static multicast
group or source-group member(s).
Use the undo igmp-snooping static-group command to disable the static (*, G) or (S,
G) joining function.
By default, this function is disabled.
Note that:
z This command works on IGMP Snooping–enabled VLANs and VLANs with IGMP
enabled on the corresponding VLAN interfaces.
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 the source-ip source-address option in your command, the
configuration will not take effect.
z If configured in Ethernet interface view, this feature takes effect on the port only if
the port 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
