Settings are: Disabled,Enabled, and Use Pulse. The default is Disabled.Use Pulse and Enabled are the two different methods usedto signal to the failover mechanism that it should switch tothe backup link:• Use Pulse The LAN link is toggled off.• Enabled The LAN link will be turned off and left off.Pulse Duration (Available if Carrier Drop Operation is setto Use Pulse.) This is the length of time that the LAN linkremains down to trigger failover. The default is 5 seconds.Block Data After Pulse (Available if Carrier DropOperation is set to Use Pulse.) Enable this option to stopdata from passing through the link when it is experiencingloss of capacity. The default is Off.Enable Ethernet If No Session Enable this option toallow management data (such as GUI, SNMP, and pingpackets) to pass, even if the Block Data After Pulse option isenabled. The default is Off.Wait for First Session Enable this option to cause thesystem to wait until the Ethernet link has been successfullyestablished following a power cycle, to keep the linkfrom being dropped due to the throughput being belowthreshold. The default is Off.First Session Validation Timer Use this setting to specifyhow long to wait before triggering a link failure due toinsufficient threshold capacity following a power cycle.The default is 0 seconds.TX Capacity Low Threshold This is the minimumallowable TX capacity; if the TX capacity goes below thisthreshold, the Ethernet link will be dropped. The default is0 Mbps.TX Capacity High Threshold This is the TX capacityrequired before a dropped link can be declared to beoperational again. The Ethernet link will remain downuntil the TX capacity reaches this threshold. The defaultis 0 Mbps. This setting should be greater than the TXCapacity Low Threshold to avoid flutter and multiple OSPFconvergences.RX Capacity Low Threshold This is the minimumallowable RX capacity; if the RX capacity goes below thisthreshold, the Ethernet link will be dropped. The default is0 Mbps.RX Capacity High Threshold This is the RX capacityrequired before a dropped link can be declared to beoperational again. The Ethernet link will remain downuntil the RX capacity reaches this threshold. The defaultis 0 Mbps. This setting should be greater than the RXCapacity Low Threshold to avoid flutter and multiple OSPFconvergences.Low Threshold Timer This is the number of continuousseconds that the radio must remain under the minimumTX or RX capacity threshold before the link is dropped. Ifset to 0, then as soon as capacity drops below a set limit,the Ethernet link will be dropped. Default is 0 seconds.High Threshold Timer This is the number of continuousseconds that the radio must remain above the maximumTX or RX capacity threshold before the link is declaredoperational again. The default is 0 seconds.
