Command: disable igmp_snooping
Success.
DES-3200-28/ME:admin#
30-9 create igmp_snooping static_group
Description
This command is used to create 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.
