Link Detection Window
Allow ARP Broadcast Probe Reply
Use the Allow ARP Broadcast Probe Reply option to control at the system-level whether the SBC allows or drops broadcast ARP replies.
Caution
For the 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.
Use the following table to specify whether the SBC allows or drops broadcast ARP replies and then click Save.

Toggle Recover Timer
Modified: for 9.2.2
The Toggle Recover Timer starts if configured with a non-zero value when the SBC stops toggling between primary and secondary ports - 5 switches in 30 seconds (2 minutes for BFD). When this timer expires, the SBC checks the link status. If the links are not good and the node switchover is possible (checks multiple conditions such as the standby node's state, peer LDG state, and so on), then it initiates the node switchover and triggers an alarm to highlight the condition. If the switchover is not possible, or the switchover doesn't succeed, then the timer restarts.
Toggle Recover Timer Parameter
Use the following table to set the Toggle Recover Timer option.
