Enabling the IGMP host tracking function
When the IGMP host tracking function is enabled, the switch can record the information of the member
hosts that are receiving multicast traffic. The member host information includes the host IP address,
running duration, and timeout time. You can monitor and manage the member hosts according to the
recorded information.

Configuring IGMP SSM mapping
Because of some possible restrictions, some receiver hosts on an SSM network might run IGMPv1 or
IGMPv2. To provide SSM service support for these receiver hosts, configure the IGMP mapping feature
on the last-hop router.
Configuration prerequisites
Before you configure the IGMP SSM mapping feature, complete the following tasks:
• Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
• Configure basic IGMP functions.
Enabling SSM mapping
To ensure SSM service for all hosts on a subnet, enable IGMPv3 on the interface that forwards multicast
traffic onto the subnet, regardless of the IGMP version running on the hosts.
To enable the IGMP SSM mapping feature:
