Set the MTU for a Network Pool Backed by Cloud Isolated Networks
You can specify the maximum transmission units (MTU) that vCloud Director uses for a network pool that is
backed by Cloud isolated networks. The MTU is the maximum amount of data that can be transmitted in one
packet before it is divided into smaller packets.
When you configure the virtual machine guest operating system and the underlying physical infrastructure
with the standard MTU (1500 bytes), the VMware network isolation protocol fragments frames. To avoid frame
fragmentation, increase the MTU to at least 1600 bytes for the network pool and the underlying physical
network. You can increase the network pool MTU up to, but not greater than, the MTU of the physical network.
If your physical network has an MTU of less than 1500 bytes, decrease the MTU of the network pool to match
the underlying physical network.
Prerequisites
Verify that you have a network pool backed by cloud isolated networks. Before you increase the MTU for a
network pool, you must ensure that the physical switch infrastructure supports an MTU of greater than 1500,
also known as jumbo frames.
Procedure
1 Click the Manage & Monitor tab and click Network Pools in the left pane.
2 Right-click the network pool name and select Properties.
3 On the Network Pool MTU tab, type the MTU and click OK.
vCloud Director modifies the MTU for the network pool and all other network pools that use the same vSphere
distributed switch.
VXLAN Network Pools
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.
When you create a provider vDC, a VXLAN network pool is created in vCloud Director. When you use this
network pool, VXLAN virtual wires are created in vCenter Server.
This pool is given a name derived from the name of the containing provider vDC and attached to it at creation.
You cannot delete or modify this network pool. You cannot create a VXLAN network pool by any other method.
If you rename a provider vDC, its VXLAN network pool is automatically renamed.
vSphere VXLAN networks provide the following benefits.
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)
For more information on VXLAN in a vCloud environment, see the vShield Administration Guide.
