This ESXi has currently a non-production VM From the Shares drop-down menu, set the relative priority of the traffic from this virtual machine as shares from the capacity of the connected physical adapter. problem. Could someone explain why its better to have a dedicated vmnic for each port group with a second card as standby rather than load balancing the two port groups over both vmnics. this causes intermittent connectivity issues as the OS continues trying to send traffic over a virtual function that is up, but it’s physical function is down. Select a load balancing algorithm to determine how the standard switch distributes the traffic between the physical NICs in a team. Hi, We have combination of both standard and distributed switch on our esx hosts. Hey, hope you are doing fine: Some quick questions Do you have any pending tasks? Is the host connected to vCenter? Do you have NSX DFW in place?
