摘要： A method of automatically determining an attached device type for a multi-port LAN switch, and configuring the port based on the attached device type is provided. The method comprises setting a LAN switch port to a port mode, and determining, during a first period of time, whether an attached device is attempting to insert at the LAN switch port. If the attached device is attempting to insert during this first period of time, the method continues by configuring the LAN switch port in the port mode. If the attached device is not attempting to insert during the first period of time, the method continue by setting the LAN switch port in an adapter mode, transmitting a test frame to the attached device, and then determining, during a second period of time, whether a response frame is received from the attached device. If a response frame is received during the second period of time, the method further includes configuring the LAN switch port in the adapter mode.

摘要： A station in a communications network determines the mode (full-duplex or half-duplex) in which it communicates with a concentrator port by establishing a Registration routine between the station and the concentrator port. The station and concentrator port exchange frames which disclose the capabilities of the concentrator port. If the concentrator port has duplex capabilities, the station enters as a duplex station. Otherwise, the station enters in a half-duplex (token ring) mode.

摘要： In a local area network switch, a first mode of operation is selected wherein frames are examined for errors as the frames are passed from a source port to a destination port. The LAN switch calculates an error rate as a function of a percentage of the frames passing through the local area network switch which have errors. In response to the error rate exceeding a high error rate threshold, the operating mode is switched to a second mode wherein the entire frame is buffered and examined for errors before the frame is passed from the source port to the destination port. Thereafter, the operating mode may be returned to the first mode if the error rate falls below a low error rate threshold. The local area network switch may also change operating modes as a function of a trend, which indicates a rate of increase or decrease of the error rate.

摘要： A display and control system utilizes graphics for providing a clear, concise and intuitive interface between the user and a complex system. Icons are utilized for selectively representing components of the complex system, the components having a configurable relationship with one another. The display and control system further utilizes a predefined array defining locations for the icons to be positioned. In a first embodiment, the interface may be utilized in a network for assisting the user to configure the network and for providing real-time monitoring of the network at the interconnect device. In a second embodiment, a display and control system utilizes graphics for providing a clear, concise interface between the user and a workstation for configuring a file for use with an application software program in accordance with the hardware installed in the server workstation. Each embodiment utilizes a predefined array defining locations for the icons to be positioned.
