IP, VLAN Direct Broadcast tab  

The following table describes the Direct Broadcast tab.


Field Description
DirectBroadcastEnable
If enabled, an Isolated Routing Port (IRP) can forward directed broadcast traffic. A directed broadcast is a frame sent to the subnet broadcast address on a remote IP subnet. By disabling or suppressing directed broadcast on an interface, all frames sent to the subnet broadcast address for a local router interface are dropped. Disabling this function protects a host from possible denial of service (DOS) attacks.
Note: This feature is enabled by default. With the feature enabled, the CPU does not receive a copy of the directed broadcast. As a result, the switch does not respond to a subnet broadcast ping sent from a remote subnet.
