All of these network resource pools are visible on the Resource Allocation tab of the vDS, as
you can see in Figure 11.18.

Two steps are involved in setting up and using NIOC. First, you must enable NIOC on that
particular vDS. Second, you must create and coni gure network resource pools as necessary. The
i rst of these steps is already complete if you create a brand-new vDS with a version set to 5.5.0—
NIOC is enabled by default.
Perform the following steps to enable NIOC on an existing vDS:
1.
If it is not already running, launch the Web Client and connect to a vCenter Server
instance. Because NIOC relies on vDS and vDS is available only with vCenter, NIOC
cannot be used when connected directly to an ESXi host.
2.
Navigate to the Networking view using the navigation bar or the home screen.
3.
Select the vDS for which you want to enable NIOC.
4.
Right-click the vDS.
5.
Click Edit Settings.
6.
Select Enabled in the Network I/O Control drop down box, and then click OK.
This enables NIOC on this vDS. The Resource Allocation tab of the vDS object will note that
NIOC is enabled, as shown in Figure 11.19.
Along with actually enabling NIOC, you can also modify existing network resource pools or
create new resource pools, if you are using a vDS version 5.0.0 or above. For a version 4.1.0 vDS,
you can neither create new network resource pools nor edit the existing network resource pools.
A network resource pool consists of three basic settings:
The i rst value is
Host
Limit
. This value specii es an upper limit on the amount of network
trafi c, in Mbps, that this network resource pool is allowed to consume. Leaving Unlimited
selected means that only the physical adapters themselves limit the network resource pool.
