create igmp_snooping static_group
Purpose To create an IGMP snooping static group on the Switch.
Syntax
create igmp_snooping static_group [vlan_name<vlan_name 8>
| vlanid < vidlist 1-4094> ] <ipaddr>
Description
The create igmp_snooping static_group command creates an
IGMP snooping static group on the Switch. 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 for routing the
packet destined for this specific group to static member ports.
The Reserved IP multicast address 224.0.0.X must be excluded
from the configured group.
T
he VLAN must be created first before a static group can be
created.
The group table is shared with MLD snooping. If MLD snooping and
IGMP snooping are enabled at the same time, the count of static
groups that can be created will be limited by the number of MLD
snooping groups that exist
(including static group and dynamic
groups).
Parameters
vlan_name <vlan_name 8> − The name of the VLAN for which the
IGMP snooping static group is to be created. Up to 8 characters can
be used.
vlanid <vidlist 1-4094> −
The ID of the VLAN for which IGMP
snooping static group is to be created. The range is from 1 to 4094.
<ipaddr> − The multicast group IP address.
Restrictions Only administrator-level users can issue this command.
Example usage:
To create the igmp snooping static group:
DGS-1100-24P/ME:admin#create igmp_snooping static_group vlanid 1
225.0.0.1
Command : create igmp_snooping static_group vlanid 1 225.0.0.1
