Jumbo Frames
The Nutanix cluster setup should have configured the NICs to the largest supported MTU size (jumbo
frames). This can be verified in Network Connections. Go to the properties of the NICs for the
ExternalSwitch, Cluster, and LiveMigration, and then click Configure. Click the Advanced tab and verify
that Jumbo Packet value is set to the highest value (typically, 9014 bytes) and modify if not currently set to
the highest value.
NOTE: The NIC for the InternalSwitch will have a jumbo frame size of 64,000. This must be verified from
the registry as the GUI properties window will not display this high value properly.
NOTE: Jumbo frames must be enabled also on the physical switch.
