We have cutover to the Cisco Business Edition 6000M Svr (M4), Export Restricted SW (BE6M-M4-K9=) for UC. Two ports on this server are connected to our 2960S switch stack . The Server runs VmWare ESXi and the VMs related to UC – Communications manager, Unity Connection, IM & Presence, etc. We are using “IP Hash” for Load balancing and active/active failover for the server VM's. We are receiving the below error message in our syslogs

Can anyone tell me what would be the correct configuration for the switch ports and the ESXi for UCS? Our current port configurations are below.
interface GigabitEthernet1/0/39
description ESXI - UC Port 1
switchport mode trunk
spanning-tree portfast trunk
spanning-tree bpduguard enable
no ip igmp snooping tcn flood
end
NJ-MDF-2960-STACK#sh run int Gi3/0/11
