Create a Network Resource Pool in Network I/O Control Version 2

Create user-defined network resource pools to customize bandwidth allocation when the traffic that flows through a physical network adapter becomes intensive.

Prerequisites

• Verify that the vSphere Distributed Switch is version 5.1 and later.
• Verify that Network I/O Control on the distributed switch is version 2.
• Enable Network I/O Control on the distributed switch. See Enable Network I/O Control on a vSphere Distributed Switch.

Procedure

1. In the vSphere Web Client, navigate to the distributed switch.
2. On the Configure tab, expand Resource Allocation.
3. Click New.
4. Enter a name and optionally a description for the network resource pool.
5. In the Limit text box. enter bandwidth limit, in Mbps, for the network resource pool with regard to the connected physical adapters on the host.
   By default, no limit on the traffic is applied.
6. From the Physical adapter shares drop-down menu, enter the shares from the physical adapter capacity that the virtual machines or the VMkernel adapters associated with the network resource pool have.

   Network I/O Control applies the configured shares when the connected physical adapter becomes saturated.

   You can select an option to set a pre-defined value, or select Custom and enter a number from 1 to 100 to set another share.

7. (Optional) From the CoS priority tag drop-down menu, select the QoS tag for marking the system or virtual machine traffic that is associated with the network resource pool, and click OK.
   The QoS priority tag represents an IEEE 802.1p (CoS) tag for defining priority of the traffic from the virtual machines associated with the resource pool at Layer 2 of the network protocol stack.

What to do next

Associate one or more distributed port groups with the network resource pool to apply the settings for bandwidth control on virtual machines. See Add a Distributed Port Group to a Network Resource Pool.
