    53 In **vSwitch0 Properties** open the **NIC Teaming** tab, and choose the //"Route based on IP hash"// option for **Load Balancing**, and also choose //"No"// for **Fallback**. On the **General** tab one can adjust number of ports supported by the virtual switch. In the latter case reboot will be required for this new setting to take effect.
