摘要： A method is disclosed for remotely monitoring network traffic through a generic network. A first data packet, which indicates a first destination network element, is received. A second data packet, which contains at least a part of the first data packet, is generated. The second data packet indicates a second destination network element that is configured to monitor network traffic. The second destination network element differs from the first destination network element.

摘要： Methods and devices are provided for detecting whether peer ports interconnecting two network devices can perform a novel protocol called Exchange Peer Parameters (“EPP”). If the peer ports are so configured to perform EPP, EPP services are exchanged between the peer ports. In a first phase, information is exchanged about peer port configurations of interest. In a second phase, the results of the exchange of information are applied to hardware and/or software of the respective ports, as needed.

摘要： Methods and devices are provided for non-disruptive monitoring of network traffic through one or more ports of a Fibre Channel network device. Preferred embodiments of the invention are used in conjunction with the switched port analyzer (“SPAN”) and/or remote SPAN (“RSPAN”) features. SPAN mode operation allows traffic through any Fibre Channel interface of a network device to be replicated and delivered to a single port on the same network device. Ingress SPAN allows the monitoring of some or all packets that ingress a specified port or ports. Egress SPAN allows the monitoring of some or all packets that egress a specified port or ports. RSPAN allows the delivery of the replicated traffic to a port on a remote network device. Filtering may be applied, for example, to SPAN packets having selected virtual storage area network numbers.
摘要翻译：提供了方法和设备，用于通过光纤通道网络设备的一个或多个端口对网络流量进行非中断监控。本发明的优选实施例与交换端口分析器（“SPAN”）和/或远程SPAN（“RSPAN”）特征结合使用。 SPAN模式操作允许通过网络设备的任何光纤通道接口的流量被复制并传送到同一网络设备上的单个端口。 Ingress SPAN允许监视进入指定端口的某些或所有数据包。出口SPAN允许监视某些或所有出口指定端口或端口的数据包。 RSPAN允许将复制的流量传送到远程网络设备上的端口。例如，可以将过滤应用于具有选择的虚拟存储区域网络号的SPAN分组。

摘要： N_Ports and F_Ports are provided with logic allowing designation of multiple virtual interfaces on a single host bus adaptor or other Fiber Channel interface, one virtual interface for each VSAN operating on the node interface. Node ports with this additional functionality are referred to as trunking N_Ports or TN_Ports. These ports have a functional design allowing creation of the multiple virtual interfaces as appropriate for the application at hand. This port design also includes logic for communicating with a peer fabric port to initialize and modify the configuration of the virtual interfaces on the TN_Port. A corresponding functional design and communication logic is provided for fabric ports, referred to herein as trunking F_Ports or TF_Ports.
