Configuring IGMP static groups
The switch will always flood the traffic destined for a group configured as static group. So the hosts will receive the traffic for static groups even if they have not subscribed for that group. You can configure a maximum of 32 IGMP static groups.
Prerequisites
You must be in an interface configuration context, as indicated by the switch(config-if)# prompt, switch(config-if-vlan)# prompt, or switch(config-lag-if)# prompt.
Procedure
Configure an IGMP static group on an interface using the following command.
ip igmp static-group <MULTICAST-GROUP-IP>
For example, the following command configures an IGMP static multicast group as 239.1.1.1 on interface VLAN 2:
The no form of the command removes an IGMP static group.
