摘要： A network device with unified management including at least one port operable at any one of a plurality of media standards, port apparatus coupled to the port(s) that monitors and controls the port(s) for each of the media standards, and a management system that interfaces the port apparatus to manage the port(s) in a unified manner with respect to all of the media standards. The management system manages each of the ports in a unified manner regardless of the particular supported media standards. In one embodiment, the network device includes a memory and maintains multiple sets of statistical information per port. The port apparatus stores the first and second sets of statistics in the memory. The management system receives a statistics request and provides a unified statistic or a corresponding statistic from either the first or the second set of statistics. For port intrusion detection and prevention, one or more ports are assigned one or more authorized source addresses. The port apparatus disables a port for all media standards if an unauthorized source address is received at that port. The management system ensures that the port is disabled for all media standards.

摘要： A network device with selectable traps that improves network management by enabling a system manager or administrator to select between multiple trap definitions. The network device includes a memory that stores a management database including a plurality of trap definitions and a programmable parameter for selecting any one of the trap definitions. The network device further includes management processing logic that executes a management agent that issues traps according a selected one of the trap definitions depending upon the programmable parameter. In the embodiment described herein, the management database includes the standard Ethernet.TM. Repeater MIB implemented according to RFC 1516 including a first trap definition and the Ethernet.TM. Hub MIB by Novell including a second trap definition. The management agent issues traps according to either one of the trap definitions depending upon the programmable parameter.

摘要： A communication protocol detection system for enabling a network system to detect and interface one or more network devices each operating according to at least one of a plurality of different communication protocols. In one embodiment, a network interface card (NIC) is capable of operating according to one of two different communication protocols, such as the 10Base-T and 100Base-TX Ethernet Standards. The NIC includes two corresponding transceivers, where the transceivers are interfaced to a network connector for interfacing an external network device. Control logic initially enables the 10Base-T transceiver to determine if link pulses are detected. If link pulses are detected, the 100Base-T transceiver is enabled to determine if it detects the link pulses. If so, the 100Base-T transceiver is used to establish communications, and if not, the 10Base-T transceiver is used. Preferably, the 100Base-T transceiver is re-enabled a predetermined number of times to determine if the network device is a 100 Mbps device. In another embodiment, a repeater includes a plurality of interface circuits, each including a plurality of transceivers. Each of the transceivers of each of the interface circuits of each port is connected to a corresponding repeater module through an array of buses. Control logic enables the transceivers one at a time within each interface circuit and correspondingly monitors the corresponding link signal. When an enabled transceiver detects link pulses, that transceiver is used to establish communications. If a link signal indicates termination of communications, enabling of the transceivers one at a time is resumed.

摘要翻译：一种通信协议检测系统，用于使得网络系统能够检测和接口一个或多个网络设备，每个网络设备根据多个不同的通信协议中的至少一个操作。在一个实施例中，网络接口卡（NIC）能够根据诸如10Base-T和100Base-TX以太网标准的两种不同的通信协议之一进行操作。 NIC包括两个相应的收发器，其中收发器连接到网络连接器，用于连接外部网络设备。控制逻辑最初使10Base-T收发器确定是否检测到链路脉冲。如果检测到链路脉冲，则使能100Base-T收发器来确定它是否检测到链路脉冲。如果是这样，则使用100Base-T收发器来建立通信，如果不是，则使用10Base-T收发器。优选地，100Base-T收发器被重新启用预定次数，以确定网络设备是否是100Mbps设备。在另一个实施例中，中继器包括多个接口电路，每个接口电路包括多个收发器。每个端口的每个接口电路的每个收发器通过总线阵列连接到相应的中继器模块。控制逻辑使收发器在每个接口电路内一次一个，并相应地监视对应的链路信号。当使能的收发器检测到链路脉冲时，该收发器用于建立通信。如果链路信号指示通信终止，则恢复一次一个收发器的使能。
