VLAN-specific MTUs ensure a consistent MTU across all network device hops in a session. OneFS allows multiple VLANs on a single interface, providing support for multiple workloads. The interfaces support multiple VLANs and the associated MTUs for those VLANs. A VLAN’s MTU must be less than or equal to the parent interface’s MTU. If the parent interface is not explicitly configured, it will inherit the MTU of the VLAN with the greatest MTU.
