Disabling Software Forwarding for Multicast Packets

Disabling Software Forwarding for Multicast Packets

Pre-configuration Tasks

Before disabling software forwarding for multicast packets, complete the following tasks:

  • Configure a unicast routing protocol to ensure normal unicast routing on the network.
  • Run the multicast routing-enable command in the system view to enable Layer 3 multicast routing globally.


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.


  1. Run system-view

    The system view is displayed.

  2. Run multicast cpu-forward disable

    Soft forwarding is disabled for multicast packets.

    By default, software forwarding for multicast packets is enabled.
