Hi Harry,

 

 

If all of the NICs are on the same subnet, you should be able to define a single VLAN and add the port(s) to the VLAN. You probably don't need to use multiple VM interfaces unless that's somehow adding resilience on the physical network.

 

 

On a normal LTM appliance, you wouldn't be able to define a virtual server on the management subnet. I assumed that would also be the case for the LTM virtual edition. I'd guess your scenario is working because TMM is using the management default route.

 

 

I would suggest defining the virtual servers on a switch port (vlan 52) and not using the management subnet. You can define a TMM route via the GUI under Networking >> Routes. For details on mgmt and TMM routing, you can check SOL
