Preparing your Network for VXLAN Virtual Wires
You must prepare your network for VXLAN virtual wires by specifying a transport VLAN and enabling IP
multicast. These preparation steps need to be done only once - you can then create multiple VXLAN virtual
wires.
Prerequisites
Go through the following checklist to prepare for creating VXLAN virtual wires in your network:
n
Ensure that you have the following software versions
n
VMware vCenter Server 5.1 or later
n
VMware ESX 5.1 or later on each server
n
vSphere Distributed Switch 5.1 or later
n
Physical infrastructure MTU must be at least 50 bytes more than the MTU of the virtual machine vNIC
n
Get multicast address range from your network administrator and segment ID pool
n
Set Managed IP address for each vCenter server in the vCenter Server Runtime Settings. For more
information, see vCenter Server and Host Management.
n
Verify that DHCP is available on VXLAN transport VLANs
n
For Link Aggregation Control Protocol (LACP), 5- tuple hash distribution must be enabled
Associating Clusters with Distributed Switches
You must map each cluster that is to participate in a virtualized network to a vDS. When you map a cluster to
a switch, each host in that cluster is enabled for VXLAN virtual wires.
Prerequisites
VMware recommends that you use a consistent switch type (vendor etc.) and version across a given network
scope. Inconsistent switch types can lead to undefined behavior in your VXLAN virtual wire.
Procedure
1 In the vSphere Client, select Inventory > Hosts & Clusters.
2 Select a datacenter resource from the inventory panel.
3 Click the Network Virtualization tab.
4 Ensure that you are in the Preparation tab.
5 In Connectivity, click Edit.
The Prepare Infrastructure for VXLAN networking dialog box appears.
6 Select the clusters that are to participate in the virtual network.
