> # FC Interfaces Trunk Config

> Field | Description
> --- | ---
> Admin | The trunking mode configured by the user. When set to nonTrunk, the port negotiates and converts the link into non-trunking mode. This port and the peer port's OperTrunkMode will not carry multiple VSAN traffic. When set to trunk, the port negotiates and converts the link into trunking mode only if the peer port is trunk or auto. When set to auto, the port is willing to convert the link to a trunk link only if the peer port is trunk.
> Oper | The current trunking mode of the port.
> Allowed VSANs | The list of VSANs which are allowed to be received/transmitted on the port when the port is operating in trunking mode. Only ports operating in trunk mode can belong to multiple VSANs.
> Up VSANs | The list of VSANs whose operational state is up, that this port is associated with. Only ports operating in trunk mode can be associated to multiple VSANs. This is applicable to only ports operating in trunk mode.
