• Tagged-access mode – The port accepts only tagged packets.
Do not enable Link Aggregation on VxRail Switch Ports
Do not use link aggregation, including protocols such as LACP and EtherChannel, on any ports directly connected to VxRail nodes.
VxRail Appliances use the vSphere active/standby configuration (NIC teaming) for network redundancy. However, LACP could be
enabled on non-system ports, such as additional NIC ports or 1G ports, for user traffic.
VxRail uses vSphere Network I/O Control (NIOC) to allocate and control network resources for the four predefined network traffic
types required for operation: Management, vSphere vMotion, vSAN and Virtual Machine. The respective NIOC settings for the
predefined network traffic types are listed in the tables below for the various VxRail Models.
