Configure the port mode on your switch based on the plan for the VxRail logical networks, and whether you are going to use VLANs to segment VxRail network traffic.
- Access mode: The port accepts untagged packets only and distributes the untagged packets to all VLANs on that port. This is typically the default mode for all ports. This mode should only be used for supporting VxRail clusters for test environments or temporary usage.
- Trunk mode: When this port receives a tagged packet, it passes the packet to the VLAN specified in the tag. To configure the acceptance of untagged packets on a trunk port, you must first configure a single VLAN as a Native VLAN. A Native VLAN is when you configure one VLAN to use as the VLAN for all untagged traffic.
- Tagged-access mode: The port accepts tagged packets only.
