00:24:51 Cisco Systems, Inc >>>> is a layer two Switch has Vlan interface with IP 192.168.0.9 
38:90:A5 Cisco Systems, Inc>>>>>  the FTD  and its have a sub interface with 192.168.0.254 

there is no duplicaion in IPs 

but always the FTD do this issuse and that why the traffic is blocked in Layer 2 .

this scenario   was a going to be a production but after a lot of failure  downtime its become a lab to test and insure that will run in production with no issues.
