Suggested Port Fault Settings for Optimal Fault Notification

In SPECTRUM 7.0 and later, the default settings for both Suppress Linked Port Alarms and Port Fault Correlation have changed. The default value of Suppress Linked Port Alarms has changed from FALSE to TRUE. This setting will suppress red alarms on ports that are connected to another down port or unreachable device. The default value of Port Fault Correlation has been changed from Management Neighbors Only to All Connected Ports. This eliminates the need for you to manually configure management neighbors before a fault occurs so that port fault correlation will work properly. If you have not previously used ‘Management Neighbors’ you will not need this setting.

Setting Suppress Linked Port Alarms to FALSE and Port Fault Correlation to Management Neighbors Only will approximate the fault notification behavior of SPECTRUM 6.6 with Service Pack 3.
CA recommends changing the default setting for Link Fault Disposition on WA_Link models. The default setting of BothPortsAndLink will result in multiple alarms if the link fails. Consider changing the setting to Link Only or Ports Only. Link Only is best in environments where the name of the WA_Link models or notes on these models is meaningful. Changing the setting to Ports Only may be better if fault notification consistency is most important. That is, regardless of the topology, you would prefer an alarm on a port model if there is a link failure.
