一个WSDL文档先是描述一系列称为端口的网络端点，然后定义与服务器交换的消息或数据的xml格式。
A WSDL document describes a series of network endpoints called ports, then defines the XML format for the messages or data being exchanged with the server.
将这种特殊的交换组合在一起就形成了WSDL端口类型。
This particular exchange is grouped together into a WSDL port type.
在本示例中，应用程序SOAP消息和WS - AT事务消息交换使用不同的端点url和TCP端口。
In this example, application SOAP messages and WS-AT transaction message exchanges use different endpoint URLs and TCP ports.
实施基本的交换机安全策略(包括：端口安全、聚合访问、除VLAN1之外的其他VLAN的管理等等)。
Implement basic switch security (including: port security, trunk access, management vlan other than vlan1, etc.)
您甚至可以使用它来识别在某个未经标识的端口上所交换的数据的类型。
You can even use it to identify the type of exchanged traffic on an otherwise unidentified port.
所有的计算机使用相同的端口号来交换信息，因此形成了一个通信环。
All machines exchange information using the same port number, thereby forming a ring for communication.
对于更大的集群，48端口可能还不够，所以可能需要更大的中心交换机。
For larger clusters, 48 ports might not be enough, so a larger central switch might be required.
这些命令把交换机上的端口1配置为执行聚合。
每个端口被连接到一个不同的SAN交换机。
由于使用更少的卡、线缆和交换机端口，虚拟I/O可以降低成本并简化服务器管理，同时仍然实现出色的网络 I/O 性能。
Virtual I/O lowers costs and enables simplified server management by using fewer cards, cables, and switch ports, while still achieving full network I/O performance.
如果无法到达这个网关，那么从您主机上的网络适配器到网关的物理连接可能有问题（例如交换机端口、线路和网卡有故障）。
If it isn't, there may be a problem with the physical connection from the network adapter on your host to the gateway (for example, a faulty switch port, cable, network card).
应该做的第一件事是，确保所有服务器使用全双工和最高的网络速度，并相应地匹配交换机端口。
The first thing you should do is make sure all servers are locked down to the highest speed possible using full duplex and the switch port is set to match.
使用以太网交换机，不会将数据包发送到所有端口，但是许多最新的交换机都提供了一个管理端口，该端口会将信息发送到所有的端口。
With Ethernet switches, packets are not echoed to all ports, but many modern switches provide a management port where the information is echoed.
交换机在其交换表中查找目标MAC地址，确定交换机出端口，通过该端口将帧转发至目的地。
The switch looks up the destination MAC address in its switching table, determines the outgoing interface port, and forwards the frame on to its destination through the designated switch port.
这些多端口网桥叫交换式集线器或以太网交换机。
These multiport bridges were called switching hubs or Ethernet switches.
用串口直连电缆连接到每台交换机的串行控制端口(9600、8 -N - 1、无流控制)，默认下不需要用户ID和密码。
Connect to the switch using the serial console port with a straight serial cable (9600, 8-n-1, no flow control) with default no user ID or password required.
直通式交换机不执行任何帧错误检查，它只查找帧的目的MAC地址，并从相应的交换机端口将帧转发。
Cut-through switches do not perform any error checking of the frame because the switch looks only for the frame's destination MAC address and forwards the frame out the appropriate switch port.
用串口直连电缆连接到交换机串行控制端口(9600、8 - N - 1、无流控制)。
Connect to the switch using the serial console port with a straight serial cable (9600, 8-n-1, no flow control).
如果你是管理着一个大型网络，好好去研究一下你的网络交换机的“端口安全”功能。
If you manage a large network, research your network switch's "Port Security" features.
有一个“端口安全”功能是允许你强制使你的交换机在每个端口只允许(IP地址对应的)一个MAC地址通过。
One "port Security" feature lets you force your switch to allow only one MAC address for each physical port on the switch.
确保测试每个物理服务器的双向通信，因为交换机对每个端口的入站和出站通信可能配置有误。
Make sure to test both ways from each physical server, as switch ports can be mis-configured for inbound and outbound per port.
选择适当的介质、线缆、端口和连接头来连接交换机跟主机或者其他网络设备
Select the appropriate media, cables, ports, and connectors to connect switches to other network devices and hosts
您可以在服务器之间拉起FibreChannel电缆和交换机，以模拟坏掉的FC 电缆；您可以禁用服务器/存储器的某个交换机端口，以模拟交换机失败。
And you can pull a Fibre Channel cable between your servers and switch to simulate a broken FC cable; you can disable one switch port of your server/storage to simulate a switch failure.
本文首先深入研究了单端口环网结构上全交换操作的实现算法。
First of all, this dissertation extensively studied the algorithms for complete exchange on single-port torus.
注意，现代交换机不会将 Ethernet数据包发送到每一个端口上，这通常会限制您从当前主机获取的信息量。
Note that with modern switches the Ethernet packets are not echoed to every port, which often limits the information you can extract to the current host.
这个体系结构由6个Ciscocatalyst交换机模块组成，每个模块有14个内部端口和4个外部的1gb端口。
The architecture consists of six Cisco catalyst switch modules with fourteen internal ports and four external 1gb ports each.
为了通过端口20 发送VLAN 383通信流，在Cisco交换机上输入以下命令
To configure VLAN 383 traffic over port 20, type the following commands on the Cisco switch
为了通过端口17发送VLAN 373通信流，在Cisco交换机上输入以下命令。
To configure VLAN 373 traffic over port 17, type the following commands on the Cisco switch.
