There is UCS C210-m2 with six Gigabit Ethernet physical interfaces.
UCCX and two nodes are CUCM should be deployed on UCS.
Is supported the configuration vSwich with aggregated physical network interfaces in a load-balancing mode (IEEE 802.3ad)?
I found an official description of the settings teaming only here: http://docwiki.cisco.com/wiki/UCS_Network_Configuration_for_Unified_CCE
But this document for CCE.
