We have a c7000 chasis with the ability to have 8 uplinks per ESX host. Only 6 are currenlty active.

I have a Virtual Switch with multiple vlan port groups and all the VMs are working fine.

Recently we've been asked to setup network load balancing for one of our VMs, so we had our Virtual Connect engineer activate the last two uplinks. We then created a new vSwitch and added the two new uplinks to this vSwitch. We then moved the VM to this new vSwitch, but we get no connectivity. What could be the issue? We also added the appropriate VLAN ID.

The VConnect engineer says everything is configured correctly and networking TEAM says the appropriate trunking is setup, so we are at a loss...
