Make sure to reenable these security services after you discover and configure the switch.PoE ConsiderationsThe PoE and PoE+ power supplied by the GS310TP switch is prioritized in ascending port order (from port 1 to port 8), with a total power budget of 55 watts with a 67.5 watt power adapter. If the power requirements for the attached powered devices (PDs) exceed the total power budget of the switch, the PD on the highest-numbered port is disabled to make sure that the PDs that are connected to the higher-priority, lower-numbered ports are supported first.Just because a PD is listed as an 802.3at PoE powered device does notnecessarily mean that it requires the maximum power limit of the specification. Many PDs require less power, allowing all eight PoE+ ports to be active simultaneously.The following table describes the PoE and PoE+ classes and switch allocations.Device ClassStandardClassDescription PowerReserved by the Device PowerDelivered to the Device*0PoE and PoE+Default power (full)15.4W0.44W–12.95W1PoE and PoE+Very low power4.0W 0.44W–3.84W2PoE and PoE+Low power 7.0W 3.84W–6.49W 3PoE and PoE+Mid power 15.4W 6.49W–12.95W 4PoE+ onlyHigh power30.0W12.95W–25.5W* Calculated with the maximum cable length of 328 feet (100 meters).

无线网络技术期末考试复习
1.无线局域网通信方式主要有哪几种，具体内容是什么？答：(1) 红外线方式无线局域网。
红外线不能穿透非透明物体而导致基于红外线方式的无线局域网系统只能在无障碍物的视距内进行工作。
红外线局域网采用小于1 μ m 波长的红外线作为传输媒体，有较强的方向性，受太阳光的干扰大；支持1 ～2Mbps 数据速率，适于近距离通信。
(2) 基于射频方式的无线局域网。
射频简称RF，射频就是射频电流，它是一种高频交流变化电磁波的简称，每秒变化超过10000 次。
将电信息源(模拟或数字)用高频电流进行调制(调幅或调频) ，形成射频信号，经过天线发射到空中；远距离将射频信号接收后进行反调制，还原成电信息源，这一过程称为无线传输。
扩频包括：直接序列扩频和调频扩频，无线局域网主要应用扩频微波技术。
2.802.11MAC 报文可以分成几类，每种类型的用途是什么？答：(1)802.11MAC报文可分成数据帧、控制帧、管理帧三类。
(2)数据帧:用户的数据报文；控制帧:协助发送数据帧的控制报文；管理帧:负责STA和AP之间的能力级的交互，认证、关联等管理工作。
3.试述AP直连或通过二层网络连接时的注册流程。
答：(1)AP通过DHCPs erver 获取IP 地址；(2)AP 发出二层广播的发现请求报文试图联系一个无线交换机；(3) 接收到发现请求报文的无线交换机会检查该AP是否有接入本机的权限，如果有则回应发现响应；(4)AP 从无线交换机下载最新软件版本、配置；(5)AP 开始正常工作和无线交换机交换用户数据报文4.干扰实际吞吐率的因素有哪些？答：①不稳定是无线通讯的本性②无线环境不停的保持变化③物理建筑的构成④AP的位置⑤共享介质：用户数、数据量5、什么叫虚拟载波侦听，它有什么效果？答：虚拟载波监听的机制是让源站将它要占用信道的时间通知给所有其他站，以便使其他所有站在这一段时间都停止发送数据。
这样就大大减少了碰撞的机会。
“虚拟载波监听” 是表示其他站并没有监听信道，而是由于其他站收到了“源站的通知” 才不发送数据。

Application Note AN008 Wireless Development Kit – User GuideOverviewEZURiO’s Wireless Development Kit provides a platform for rapid prototyping of wireless connectivity, providing options for the development of Bluetooth, 802.11 and GPRS applications1. IntroductionThe EZURiO Wireless Development Kit is designed to support the rapid development of applications and software for the EZURiO range of Bluetooth and Wireless LAN modules. The development board will also allow you to develop applications and services for a Siemens MC55 GPRS module when connected to an external power supply.Package ContentsDevelopment Board The mother board is used to mount your chosen wireless module, providing the RS232 interface and access to all the module interface pins.USB cable The USB cable can be used as one of the options to provide power for the dev kit via the onboard connector.Serial cable RS232 interface cable to provide the communication between your host pc and your choice of wireless module. The serial cable canalso be used as an option to power the motherboard and modulefrom pin 9.Bluetooth USB adapter Versions of the Development Kit which include a Bluetooth module include a FREE USB Bluetooth adaptor and Windows protocols stack.Three Mounting Spacers Mounting spacers for securing your choice of Bluetooth or Wireless LAN module to the motherboardEZURiO terminal application PC based terminal emulation software, specifically designed to help the development and diagnostics of applications on the EZURiO range of modulesDocumentation A development kit user guide, board design circuit diagrams and aquick start guide2. Wireless Module Development BoardThe development board allows the EZURiO Bluetooth or Wireless LAN Module to be connected to a PC. The development board provides RS-232 level conversion through a standard 9 way D type connector to all pins of the 40 way and a 50 way Hirose connecters used by Bluetooth or Wireless LAN modules.A separate connector is provided for PCM audio for use with the 40 way EZURiO Bluetooth modules. This can be connected to a customer’s own evaluation board or a range of codec accessory boards that EZURiO will make available.3.Getting to know the Development Board40 way connector50 way connector9 way DEERS-232 Level ShifterPSU Options:USB 2.1mm JackScrews orReset SwitchPCM Output4. Power SupplyMinimum Typical Maximum Input Voltage3.6V5V6VThe development board provides a number of options to provide power to the module.• 5V Power from a USB port• Power from an external power supply via screw terminals• Power from a external mains power block via a 2.1mm DC connector • Power via Pin 9 of the RS232 adaptorThe developer kit includes a USB cable to provide power to the development board. This should be plugged into a PC USB port, a USB hub, or a mains adaptor with a USB output. If a hub is used, it should be a powered USB hub to ensure that sufficient current is available at the port being used. Both the Bluetooth Intelligent Serial Module (BISMII) and the Wireless LAN (WISM) modules can be driven by the current available at a USB port.When using a Siemens MC55 GPRS modem in the development board, an external power supply with a minimum current capacity of 2A MUST be used and connected to the power supply terminals.Jumper JP2 is used to select an external power source on the screw terminals.SW1 (slide switch) provides the power on / off for the module but does not isolate the power from other components of the development board.S1 (push button TACT switch) provides a reset signal to both the 40 way and 50 way connectors. Note that the reset polarity is different for the 40 and 50 way pinouts. This is accomplished by circuitry on the development board, providing an active HIGH reset for the 40 way connector and an active LOW for the 50 way connector. Users connecting a reset signal to the test points one the board, should be aware that there is a 10kΩpulldown on the 40 way reset pin, and a open collector transistor connected to the 50 way reset pin. Refer to the schematics on the CD.An alternative method of powering the development kit is to supply power to Pin 9 of the RS232 connector. If this method is used, no other power supplies should be connected to the board. Jumper 8 on the development board needs to be moved to allow power to be derived from pin 9 of the serial port. In this mode the ring indicator will not be available from the RS232 interface.5.RS-232 Serial InterfaceThis provides a direct interface to any standard RS-232 port on a PC or peripheral. The 9 way D type connector can be plugged straight into a serial port on a PC or peripheral. If access to the serial port is restricted, the serial cable provided can be used to connect the development board to the PC.The development board contains a level shifter on the RX, TX, CTS, RTS, DTR, DSR, RI and DCD signals that converts between the 3.3V levels required on the module to the standard RS-232 levels.The level shifter can have its outputs permanently enabled, or enabled only when themodule is active, i.e. not in sleep mode. The latter is useful when a defined state is required at the RS232 interface as the module enters and exits its low power modes.The behaviour is determined by the setting of J10, which is located behind the USB socket at the rear of the board. The normal setting is Always Enabled.Note that the 50 pin formats of the WISM and the Siemens MC55 do not support the output line to drive this input. When using modules on the 50 pin connector J10 must be set to Always Enabled.J10 SettingsIf digital signal levels are required at the RS232 connector, these can be achieved by removing the level shifter and populating the PCB pads that are then exposed with zero ohm links.6. SoftwareThe development board will connect any EZURiO Bluetooth or Wireless LAN Module to theserial port of a PC or other device. From a PC you can communicate with the module using any Terminal Emulator software such as HyperTerminal, Procomm or the EZURiOTerminal application supplied.EZURiO Terminal is a terminal emulation application capable of running on Windows 98, Me, 2000 and XP operating systems. It was developed specifically to aid development and testing of EZURiO Modules. It allows connection to serial devices using any combination of the following communications parameters:COM Port: 1 to 255Baud rate: 300 to 921600Parity: None,EvenOdd,Data Bits: 7 or 8Stop Bits: 1 or 2CTS/RTSHandshaking: NoneorThe benefits of using EZURiO Terminal are:•Status of DSR, CTS, DCD and RI are continuously displayed•DTR on the host PC can be directly controlled via a check box•RTS can be directly controlled•BREAK signals can be sent•Scripts can be run to assist•Additional built-in features speed developmentEZURiO includes a “Data Transfer Test” mode allowing data to be sent as fast as the handshaking will permit. This feature is useful for testing the bit transfer rate of a Bluetooth connection.The EZURiO terminal application is provided on the CD within this kit; updates are also available from our website: 7. Interface Specification7.1 Serial port connectorThe pin-out for the 9 way D type connector is shown in the table below.Note: The direction is as seen from the Module’s perspective.Pin Description Signal Direction1 Data Carrier Detect DCD Output2 Transmit Data TD Output3 Receive Data RD Input4 Data Set Ready DSR Input5 Ground GND ---6 Data Terminal Ready DTR Output7 Clear To Send CTS Input8 Request To Send RTS Output9 Board Power or Ring Indicator RI or Power Output7.2 Module Breakout connectorsAll of the pins from the 40 way and 50 way connectors, WITH THE EXCEPTION OF Vccare available on each of two rows of plated through holes on the long sides of the board. These translate directly to the pin layout of the module receptacles, allowing access to all of the module pins. Pin 1 is indicated by an ident on the silk screen.The format of the holes allows the fitting of your choice of connectors, or they can be used for directly soldering test wires to the board. Both are laid out on a standard 0.1” (2.54mm) pitch.7.3 PCM InterfaceThe Development board provides a dedicated audio interface for the Bluetooth modules. The pins provide the developer with access to the module’s PCM lines as well as providing power to allow additional audio hardware to be developed. EZURiO has developed a range of audio codec interface boards that can be plugged directly onto this interface to support audio application development.7.4 Board configuration jumpersJumper DescriptionJP1 Breaks the supply to the module for current measurementsJP2 Selects external power supply for Siemens modulesJP8 Selects pin 9 powerJ10 Selects low power mode for RS-232 level shifter8. Other Features8.1 Power Consumption MeasurementA removable jumper JP1 is provided to break the supply line directly to the modules, allowing the current consumption to be measured. For normal operation JP1 must be fitted.Note that this only measures the current consumption of the module, and not of the level shifter or other peripheral circuitry.8.1 USB AccessUSB access can be provided to allow a direct USB connection to a Bluetooth HCI module. To do this remove resistors R17 and R18 from the development kit and replace them with zero Ohm links.Note that if this is done and the unit is then connected to a USB host port, it will be powered from that same port. Do not attempt to use any other power source for the development kit when operating in this mode.This is not relevant for modules with a UART interface.9.

Mini-Circuits USB RF SP8T Switch 产品说明书
USB-1SP8T-63HUSB RF SP8T Switch50Ω 10 to 6000 MHzSolid stateCase Style: QM2280Product OverviewMini-Circuits’ USB-1SP8T-63H is a low cost, absorptive SP8T switch with USB control. The fast switching, solid state switch operates from 10 MHz to 6000 MHz with 200 ns typical switch transition speed. High linearity (+50 dBm typ IP3), and high isolation (80 dB typical) allow the model to be used for a wide variety of RF applications.Full software support is provided for USB control, including our user-friendly GUI application for Windows and a full API with programming instructions for Windows and Linux environments (both 32-bit and 64-bit systems). The latest version of the full software package can be downloaded from https:///softwaredownload/solidstate.html at any time.The USB-1SP8T-63H is housed in a compact, low profile, rugged metal case (6.5” x 2.00” x 0.475”) with 9 SMA (F) connectors (COM,and J1 to J8), a USB Mini-B port for power and two data bus connectors for Master / Slave connections to other modules.The Big Deal• Very high isolation, 80 dB typ• High speed switch transition, 200 ns typ • High power handling, +30 dBm max • Daisy-chain control of up to 35 modulesTypical Applications• Cellular handset / BTS testing• High volume production testing / ATE • Design verification testing• RF signal routing / switch matricesModel No.DescriptionQty.USB-1SP8T-63H Switch Matrix1Included AccessoriesMUSB-CBL-3+2.6 ft USB cable1Rev.

The most significant factor is the host PC, influenced by CPU load and USB protocol. The time shown is an estimate for a medium CPU load and USB 2.0 connection.7 Current consumption specified for a single unit without any slave modules.8 Pass through current is the maximum current handling of a unit with slave modules attached. If controlling a large number of slave modules additional power supplies should be included to ensure this limit is not exceeded.

The module connected to the PC USB port will be assigned address 0 (Master), the first module connected to it will get address 1(slave) and subsequent modules incrementing up to address 34 (slave).Connections between modules will be made using the serial in/out ports with the module connected to the PC as a master and all others as slave modules. All control will be through the master module (address zero) which is the only one communicating with the PC. Serial control out port of each module should be connected to the serial control in port of the next module. Power will be supplied from the PC via the master module up to a maximum of 500mA.If connecting USB-1SP8T-63H units in series, additional power supply will generally be needed every six to nine modules. If mixing modules of different types ensure the max current through any unit does not exceed 500mA. All power supplies should be connected to the module via the module’s USB port, connecting an additional power supply will automatically cut off power draw from the serial control in port for that module.The Serial master/slave bus allows connecting modules of different types to the same daisy chain as long as all support Mini-Circuits Dynamic addressing setup. To add a new module to the set up simply connect the module to the setup and refresh the address listing, no need to reset any of the existing modules or assign addresses manually.Connecting slave units should be done only with control cables provided by Mini-CircuitsinchmmOutline Dimensions ( )A B C D E F G H J K LWT.

安全协议的分析与思考
认证和加密的次序 会话密钥产生的复杂度与安全通道的粒度有关
对应用层安全来说，由于需求明确，通常采用一次一密， 对应用层安全来说，由于需求明确，通常采用一次一密，会话密 钥的产生比较简单 对传输层安全来说，安全保护的是某个连接。（如 协议， 对传输层安全来说，安全保护的是某个连接。（如SSL协议，虽 。（ 协议 然可用于保护所有的应用层协议，但在邮件保护中， 然可用于保护所有的应用层协议，但在邮件保护中，由于邮件服 务器到本地的路径是用POP/MAPI协议 ，所以需要分段 所以需要分段SSL，较 务器到本地的路径是用 协议 所以需要分段 ， 为复杂） 为复杂 对于网络层安全（ ），安全通道保护的可能是某个数据 对于网络层安全（如IPSEC），安全通道保护的可能是某个数据 ）， 也可能是一个端－ 也可能是LAN-LAN，因此会话密钥 流，也可能是一个端－端，也可能是 ， 的生成最为复杂。 的生成最为复杂。 对于链路层安全来说，安全保护只限于一截链路， 对于链路层安全来说，安全保护只限于一截链路，加密算法和密 钥分发都不宜复杂
