Set the MTU for a Network Pool Backed by Cloud Isolated Networks
You can specify the maximum transmission unit (MTU) Cloud Director uses for a network pool that is backed
by Cloud isolated networks. MTU is the maximum amount of data that can be transmitted in one packet before
it is split into smaller packets.
When both the virtual machine guest operating system and the underlying physical infrastructure are
configured with the standard MTU (1500 bytes), then the VMware network isolation protocol will fragment
frames. To avoid frame fragmentation, you should increase the MTU to at least 1524 bytes for both 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.
In the unlikely case that your physical network has an MTU of less than the standard of 1500 bytes, then you
should decrease the MTU of the network pool to match the underlying physical network.
Prerequisites
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 Edit Network Pool.
3 On the Network Pool MTU tab, type the MTU and click OK.
Cloud Director modifies the MTU for the network pool and all other network pools that use the same vNetwork
distributed switch.
