Usage Guidelines

Usage Scenario

When multicast users access a multicast group through a sub-interface, multicast group members change, and the switch generates new Layer 3 multicast forwarding entries until the aging time of multicast member interfaces expires. To enable the switch to generate new multicast forwarding entries immediately, use the reset igmp-snooping qinq-port-info command to clear old Layer 3 multicast forwarding entries.

Configuration Impact

During the execution of the reset igmp-snooping qinq-port-info command on a sub-interface, multicast traffic to hosts connected to this sub-interface will be interrupted.

Precautions

This command cannot delete static group membership.

Example

# Clear group membership of all multicast groups on QinQ termination sub-interface GE0/0/18.1.
