Note
Exception: only supported on VSP 4450 Series.
Enables or disables support for IP Directed Broadcast in hardware without requiring CPU intervention. Setting this boot flag will put port 1/46 into loopback mode, making it unusable for external connections, so you need to move any existing connections on this port first. After setting this boot flag, save the configuration, and then restart the switch.
The default value is disabled.
Important
The software cannot be upgraded or downgraded to a software release that does not contain this directed broadcast hardware assist functionality without first disabling this feature and saving the configuration.
