Modified: for 7.2.2

Use the link detection allowArpBroadcastProbeReply parameter to control at the system-level whether the SBC allows or drops broadcast ARP replies.

Note

For SBC SWe deployments, this parameter is not applicable and the SBC allows any type of broadcast ARP packet, regardless of the setting. Be aware that if your network carries a high volume of opCode Request packets, the SBC can be susceptible to a false indication of link failure. This type of packet is typically sent during broadcast ARP storms.

Note

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