Usage Guidelines

Usage Scenario

The igmp-snooping group-policy command is used to limit the range of multicast groups that user hosts can join.

Prerequisites

IGMP snooping has been enabled globally and in a VLAN.

Rules have been configured for a specified basic ACL.

Configuration Impact

After the igmp-snooping group-policy command is run, user hosts cannot join multicast groups beyond the configured multicast group range. If the igmp-snooping group-policy command is run more than once, all configurations take effect.

Precautions

If no IGMP version is specified, the device will apply the configured group policy to all IGMP messages (IGMPv1/IGMPv2/IGMPv3 messages) and the ACL configured for the group policy must be a basic ACL.

Example

# Allow the user hosts connected to GE 0/1/1.1 to join only multicast group 225.1.1.123.
