Use the Link Detection window to control at the system-level whether the SBC allows or drops broadcast ARP replies.

Note

For SBC 7000 series systems, enabling this parameter results in the SBC allowing through opCode Reply packets and dropping opCode Request packets.

Caution

For SBC SWe deployments, enabling this parameter results in the SBC allowing through both ARP Broadcast opCode Reply and opCode Request packets. This can make the SBC susceptible to a false indication of link failure if the network carries a high volume of opCode Request packets. This type of packet is typically sent during broadcast ARP storms.

From the SBC main window, go to All > System > Admin > Link Detection

The Link Detection window opens.
