Configuring jumbo frames is a best practice for both VMware vMotion and vSAN networks, both of which are core components of Cloud Foundation. All the switch ports on the modular switches and up to the aggregation switches used to connect multiple Dell PowerEdge MX7000 chassis enclosures together must be configured for jumbo frames. It is also recommended to configure jumbo frames on the VXLAN network. The validation phase run as part of the Cloud Foundation installation process tests end-to-end connectivity of all specified devices, but fails if the jumbo frames are not correctly configured.
