You cannot create a LAG with one port of ESM1, and one port of ESM2.
There are some limited options available for the server ports - see http://www.intel.com/support/motherboards/server/mfsys25/sb/CS-028603.htm
What kinds of teaming are supported?
Adapter Fault Tolerance and Adaptive Load Balancing are supported with a single switch. Switch Fault Tolerance is supported with dual switches and a mezzanine card, and is set via Device Manager or the NIC driver.
