  • Obtaining path information related to a bridged network
    Publication number: 20050053006
    Abstract: Path information is obtained in a bridged network by generating an L2 frame with a special MAC address in the header and a target MAC address embedded in the payload of the frame. The special MAC address in the header of the frame triggers the collection of path information as the frame traverses the bridged network while the target MAC address in the payload of the frame is used to forward the frame in the bridged network. In an embodiment, the destination MAC address of the frame is set to a special MAC address that identifies the frame as a “trace-path” frame, for example, a multicast MAC address.
