Description: The value of tLagholdTimeDown specifies the timer in 0.1 second units which controls the delay between detecting that a LAG is down (all active ports are down) and reporting it to the higher levels. The default value for this timer is 0, i.e. the higher levels are informed directly. A non zero value may be configured e.g. when active/standby signalling is used in a 1:1 fashion to avoid that the higher levels are informed during the small time interval between detecting that the LAG is down and the time needed to activate the standby system.
