This read-only enumerated value, in a table row keyed by VXLAN ID and interface name, reports how incoming VLAN tags on a Layer 2 interface are treated as VXLAN payload: all(1), fromSublayer(2), or default(255). It affects whether an admin sees the original customer VLAN tag preserved inside the VXLAN-encapsulated frame or stripped before encapsulation, which matters for multi-tenant tag preservation. A setting of all(1) on this interface means every ingress tag is carried through as payload rather than being adjusted or removed.
