vlanPortIslAdminStatus 1.3.6.1.4.1.9.5.1.9.3.1.7

Indicates the administrative status set on the trunk port while the operational status is the one that indicates whether the port is actually trunking or not. If the status is set to off(2), the port is permanently set to be a non-trunk. If the status is set to onNoNegotiate(5), the port is permanently set to be a trunk and no negotiation takes place with the far end to try to ensure consistent operation. If the status is set to on(1), the port initiates a request to become a trunk and will become a trunk regardless of the response from the far end. If the status is set to desirable(3), the port initiates a request to become a trunk and will become a trunk if the far end agrees. If the status is set to auto(4), the port does not initiate a request to become a trunk but will do so if it receives a request to become a trunk from the far end.
