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 the 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:

switch# configure terminal
switch(config)# interface vlan 2
switch(config-if-vlan)# ip igmp static-group 239.1.1.1

And the following command configures an IGMP static group on interface 1/1/1:

switch# configure terminal
switch(config)# interface 1/1/1
switch(config-if)# ip igmp static-group 239.1.1.10

The no form of the command unconfigures an IGMP static group.
