Manual Routing Gigabit Ethernet Redundancy Threshold. This is the percent used to determine Fail Over from Primary to Secondary, and Switch Back from Secondary to Primary. If a value of zero is specified, Fail Over or Switch Back will not occur. Range is 0 to 100%. Primary Fail Over to Secondary: FailOver = (PrimaryRate) < (Threshold * SecondaryRate) The Primary must remain below the threshold for apexGbeConfInRedundMonitorPeriod. Fail Over will not occur when apexManRteGbeInRedSuspend is set to 'suspended'. Secondary Switch Back to Primary: SwitchBack = (PrimaryRate) >= (Threshold * SecondaryRate) The Primary must remain at or above the threshold for apexGbeConfInRedundMonitorPeriod seconds. The APEX will delay Switch Back an additional apexGbeConfInRedundSwitchTime seconds. Switch Back will not occur when apexManRteGbeInRedSuspend is set to 'suspended' or apexGbeConfInRedundAutoSwitchBack is 'disabled'.
