create igmp_snooping static_group
Purpose
Used to create IGMP snooping static group information on the Switch.
Syntax
create igmp_snooping static_group [ vlan <vlan_name 32> | vlanid <vidlist> ]
<ipaddr>
Description
This command allows the creation of an IGMP snooping static group. Member ports can
be added to the static group. The static member and the dynamic member port form the
member ports of a group.
The static group will only take effect when IGMP snooping is enabled on the VLAN. For
those static member ports, the device needs to emulate the IGMP protocol operation to
the querier, and forward the traffic destined to the multicast group to the member ports.
For a layer 3 device, the device is also responsible to route the packet destined for this
specific group to static member ports.
The static member port will only affect V2 IGMP operation.
The Reserved IP multicast address 224.0.0.X must be excluded from the configured
group. The VLAN must be created first before a static group can be created.
Parameters
vlan <vlan_name 32>
−
The name of the VLAN for which to create IGMP snooping static
group information.
vlanid < vidlist >
−
The list of the VLAN IDs for which to create IGMP snooping static
group information.
<ipaddr>
−
The static group address for which to create IGMP snooping static group
information.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To create a static group 226.1.1.1 for VID 1:
