Prerequisite Description
CoS priority tag for system traffic The distributed switch does not have network resource pools that have a CoS tag
assigned.
User-defined network resource
pools
The distributed switch does not contain user-defined resource pools for virtual machine
bandwidth control.
Resource allocation policy override No distributed port groups on the switch allow overriding the Network I/O Control policy
on individual ports.
6 If the distributed switch contains user-defined resource pools, transfer the shares from the user-
defined resource pools in version 2 to shares of individual VM network adapters in version 3, and
click Next.
Transferring the shares enables you to keep certain bandwidth allocation settings of virtual machines.
Note The limits on user-defined network resource pools are not preserved during the conversion.
7 Review the upgrade settings and click Finish.
What to do next
n
Assign a reservation bandwidth quota to a group of virtual machines that are connected to the switch
by creating network resource pools and associating them with the distributed port groups to which the
virtual machines are attached. See Create a Network Resource Pool and Add a Distributed Port
Group to a Network Resource Pool.
If you have transferred the original shares from version 2, they are enforced when you associate
network resource pools with the port groups of the switch.
n
Allocate bandwidth from the quota to individual virtual machines by using shares, reservation, and
limit. See Configure Bandwidth Allocation for a Virtual Machine.
Enable Network I/O Control on a vSphere Distributed
Switch
Enable network resource management on a vSphere Distributed Switch to guarantee minimum bandwidth
to system traffic for vSphere features and to virtual machine traffic.
Prerequisites
Verify that the vSphere Distributed Switch version is 5.1.0 and later.
Procedure
1 In the vSphere Web Client, navigate to the distributed switch.
2 From the Actions menu, select Edit Settings.
3 From the Network I/O Control drop-down menu, select Enable.
4 Click OK.
