Setting the aging time for Layer 2 multicast forwarding entries triggered by multicast traffic can balance the forwarding efficiency and system performance.
If a multicast source does not send multicast data for some multicast groups, relevant (S, G) entries need to be deleted. If a device does not receive any multicast data sent by a multicast source to a multicast group within the aging time of the corresponding (S, G) entry triggered by multicast traffic, the device deletes the multicast entry, improving device performance.
Before setting the aging time for entries triggered by multicast traffic, enable IGMP snooping both globally and in a specified VLAN or VSI.
The system view is displayed.
The aging time is set for entries triggered by multicast traffic in the VLAN or VSI.
The configuration is committed.
