High availability Failover problem

hii...thanks for the response... : ), my accomplish is to redundant function link controller in case if one of interface BIG-IP Appliance get failure, it will failover to peer device through Device Service Clustering (DSC), (not system failure like lose power or crash system, just one of interface example "internal")

in my simulation i try configure BIG-IP redundant with 2 device with method DSC Active-Active, so next i tried to disabled interface "internal" let we say on "bigip1" handle "traffic-group1", than will be damaged all Virtual Server will be down or "red", i hope with DSC it will be Failover to peer cluster let we say "bigip2" handle "traffic-group2" because on internal bigip2 interface is good, but that not happened, all Virtual Server handled by traffic group1 on bigip1 cant be access

next i try to shutdown system "bigip1" then all Virtual server handled by traffic-group1 on bigip1 can be failover to bigip2 and can be access, so i get conclussion from configuration DSC is it can be failover to next peer device if system bigip appliance is completely down, is that true?

because i cant find feature when i configuration DSC to trigered and monitor interface status when one of get failure it will be failover from traffic-group1 on bigip1 to trafic-group2 on bigip2 rather than system failure or shutdown, Thanks ...
