Create an Isolation-Backed Network Pool
To create an isolation-backed network pool, create a VMWNetworkPool element whose type attribute has the
value FencePoolType, and POST the element to your cloud's add link for networkPools.
An isolation-backed network pool is backed by one or more vCenter isolated networks, and provides traffic
isolation from other hosts. The system provisions isolated networks automatically. Before creating an isolation-
backed network pool, consider using the VXLAN pool that is created automatically when you create a Provider
vDC
vSphere VXLAN networks are based on the IETF draft VXLAN standard. These networks support local-
domain isolation equivalent to what is supported by vSphere isolation-backed networks. In addition, they
provide:
n
logical networks spanning layer 3 boundaries
n
logical networks spanning multiple racks on a single layer 2
n
broadcast containment
n
higher performance
n
greater scale (up to 16 million network addresses)
Prerequisites
n
Verify that you are logged in to the vCloud API as a system administrator.
n
Verify that you know your cloud's add URL for networkPools. See “Create a Network Pool,” on
page 222.
n
Verify that at least one vCenter server attached to your cloud has network resources available. See
“Retrieve a List of Available Portgroups and Switches from a vCenter Server,” on page 203
Procedure
1 Choose a vCenter server to provide a switch for the network pool.
2 Create a VMWNetworkPool element that specifies the properties of the network pool.
3 POST the VMWNetworkPool element you created in Step 2 to your cloud's add URL for networkPools.
