I have requested some function from customer about clusterXL monitoring interface.
There is a clusterXL environment > one External , two internal cluster group.
if one internal interface down on Active member, Active status dosen't have to take over to Standby machine.
It means ..this function is to disable cluster interface monitoring on specific interface?
( it's not a private interface)
Other vender like Fortinet or Juniper has this function to disable monitoring.
