# Assigning a Multicast Group to an Interface

You can assign an interface to send and receive all traffic for a particular multicast group. This feature enables you to control the IGMP traffic and to test the behavior of multicast protocols in the network.

ip igmp static-group

- Use to send and receive all traffic for a multicast group from a specific interface.
- The interface sets no timers for this group.
- Example
  host1:boston(config-if)#ip igmp static-group 225.1.2.3
- Use the no version to stop the interface from sending all traffic for the group.
- See ip igmp static-group.
