Cisco CML strange issue with cisco ASA trunk

I am seeing very strange issue and now i am losing my mind so thought ask you folk. I have following two components connected point to point on Cisco CML 2.0

[nxos-9000v]--------------------[ASA]

9000v config

interface Vlan10 no shutdown ip address 10.10.10.2/24 ! interface Ethernet1/3 description connected to ASA switchport mode trunk switchport trunk allowed vlan 10 

ASA config

interface GigabitEthernet0/0 no nameif no security-level no ip address ! interface GigabitEthernet0/0.10 vlan 10 nameif inside security-level 100 ip address 10.10.10.1 255.255.255.0 

I can't ping 10.10.10.2 from ASA

But if i configure 9000v e1/3 interface switchport and ASA side if i remove VLAN config and put direct IP on g0/0 interface then everything works. Am i missing something to configure cisco ASA vlan config?
