The type of VLAN encapsulation desired to be used on this trunk port. It is either a particular type, or 'negotiate' meaning whatever type results from the negotiation. negotiate(5) is not allowed if the port does not support negotiation or if its vlanTrunkPortDynamicState is set to on(1) or onNoNegotiate(5). Whether writing to this object in order to modify the encapsulation is supported is both device and interface specific.
