For switch based platforms, the bcm56xxd daemon monitors the active/standby state using the failover.bigipunitmask DB variable and if this indicates a transition from Active to Standby, it downs external links and starts a timer for re-enabling the links after a customer-specified delay as per the failover.standby.linkdowntime DB variable.
No support for external link down time on network failover.
This occurs on BIG-IP 2000 series and 4000 series platforms.
External link down time on network failover is now supported on BIG-IP 2000 series and 4000 series platforms. You can find the Link Down Time on Failover option in the GUI under Device Management :: Device Groups :: [device_group_name] :: Failover.
