Edit the settings of either a system or user-defined network resource pool to change the priority of the traffic that is associated with the pool in Network I/O Control version 2.

Prerequisites

Procedure

  1. In the vSphere Web Client, navigate to the distributed switch.
  2. On the Configure tab, expand Resource Allocation.
  3. Select a network resource pool from the list and click Edit.
  4. In the Limit text box, set a limit on the bandwidth that the VM network adapter can consume.
  5. 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.

  6. (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.

Results

Network I/O Control version 2 applies the new settings for bandwidth control to the VMkernel and virtual machine adapters on the distributed port groups that are associated with network resource pool.
