A method of transmitting data between an interface device and an inter-switch link includes receiving a frame on the inter-switch link and determining whether the frame's payload is an encapsulated frame and forming a modified frame when the frame's payload is an encapsulated frame. The header of the modified frame includes a subset of data from the received frame's header. A link interface device is also featured. The link interface device includes a data transmitting and receiving unit, frame type circuitry, and frame modification circuitry. The data transmitting and receiving unit couples the device to an inter-switch link to transmit and receive data frames on the link. The frame type circuitry can receive data frames from the transmitting and receiving unit and can determine whether a payload segment in the received data frame is an encapsulated frame. The frame modification circuitry is coupled to the frame type circuitry and can modify frame header segment data when the payload segment in the received frame is an encapsulated frame.
