Single iApps, two traffic-groups

Is it possible to create multiple virtual-addresses on differents traffic-groups using iApps? I have two traffic-groups, and I want to create a virtual-server on each. VS_A -> VIP_A -> TG_...

Seems to work. Most things that are possible with TMSH are possible with iApps.

tmsh::create cm traffic-group /Common/TG_A
tmsh::create cm traffic-group /Common/TG_B

tmsh::create ltm virtual-address 10.1.1.1 traffic-group TG_A
tmsh::create ltm virtual-address 10.1.1.2 traffic-group TG_B

tmsh::create ltm virtual VS_A destination 10.1.1.1:80
tmsh::create ltm virtual VS_A destination 10.1.1.2:80

Hi,

Thank you for your response.

The problem is that creating a virtual-address using iApp, traffic-group argument is never taken into account.

I created an iApp with your example. After the first run, 10.1.1.1 is in traffic-group-cbv, not in TG_A.

The iApp template :

The Application Service :

The result :

Is it possible to ignore the traffic-group setting on the second screenshot?

After a little more research, it appears that this is intentional. The iApp itself (sys application service) has a traffic-group property, and all objects owned by the iApp are required to belong to the same traffic group. Attempting to change the traffic-group of one of the objects results in an error such as "can not be modified because it is in use by application (/Common/test.app/test) that does not have a matching traffic group." Furthermore, in my example from above, setting the iApp's traffic-group automatically changes the traffic group of both virtual-addresses.
