7 For each selected cluster, type the VLAN used for VXLAN transport.
For information on retrieving the VLAN ID of the VXLAN VLAN, see the vSphere Networking
documentation.
8 Click Next.
9 In Specify Transport Attributes, type the Maximum Transmission Units (MTU) for each virtual distributed
switch. MTU is the maximum amount of data that can be transmitted in one packet before it is divided
into smaller packets. VXLAN traffic frames are slightly larger in size because of the encapsulation, so the
MTU for each switch must be set to 1550 or higher.
10 Click Finish.
You have now pooled your compute resources and are ready to create VXLAN virtual wires on demand.
Assign Segment ID Pool and Multicast Address Range to vShield Manager
You must specify a segment ID pool to isolate your network traffic, and a multicast address range to help in
spreading traffic across your network to avoid overloading a single multicast address.
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 Click the Segment ID tab.
6 Click Edit.
The Edit Settings dialog box opens.
7 Type a range for segment IDs. For example, 5000-5200.
8 Type an address range. For example, 224.1.1.50-224.1.1.60.
9 Click OK.
Create a VXLAN Virtual Wire
Prerequisites
Your network is prepared for VXLAN virtual wires.
Add a Network Scope
A network scope is the compute diameter spanned by your virtualized network and may contain multiple
VXLAN virtual wires.
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 Click the Network Scopes tab.
