Usage Guidelines

Usage Scenario

In most cases, the switch forwards packets based on software before the hardware forwarding is completed. Then, the switch forwards packets based on hardware. Soft forwarding for multicast packets must be disabled on the switch to prevent packet loss and disorder caused by the low forwarding speed and first packet cache mechanism of soft forwarding.

Prerequisites

IP multicast routing has been enabled using the multicast routing-enable command.
