4.2.6.4.2Ethernet Broadcast Filtering (SU only)
The Ethernet Broadcast Filtering menu enables defining the layer 2 (Ethernet) broadcast and multicast filtering capabilities for the selected SU. Filtering the Ethernet broadcasts enhances the security of the system and saves bandwidth on the wireless medium by blocking protocols that are typically used in the customer's LAN but are not relevant for other customers, such as NetBios, which is used by the Microsoft Network Neighborhood. Enabling this feature blocks Ethernet broadcasts and multicasts by setting the I/G bit at the destination address to 1. This feature should not be enabled when there is a router behind the SU.
The Ethernet Broadcast Filtering menu includes the following parameters:
Filter Options
DHCP Broadcast Override Filter
PPPoE Broadcast Override Filter
ARP Broadcast Override Filter
