9 2 Product Overview Developed by Hangzhou H3C Technologies Co., Ltd (hereinafter referred to as H3C), H3C WA series wireless local area network (WLAN) access points (APs) (hereinafter referred to as the WA series) can be widely applied in wireless networks providing WLAN services to users. The WA series can operate in both fat and fit modes. When they serve as fit APs, they need to cooperate with wireless controllers or unified switches; when they serve as fat APs, they can independently provide wireless access for WLAN users. The WA series allow you to switch between the two modes at the CLI to accommodate to different network sizes. Thus, flexibility is achieved. H3C WA series WLAN access points include WA2110-AG, WA2200 series, and WA2600 series. Table 2-1 shows the applicable models and working mode. The WA2110-AG supports a/b/g, and serves as fit APs to cooperate with wireless controllers or unified switches. The WA2200 series supports a/b/g, and can switch between the fit and fat modes to accommodate to different network sizes. The WA2600 series supports a/b/g/n, and can operate in both fat and fit modes. It provides an access rate of six times the traditional a/b/g network and covers a larger area. The WA 2600 series adopts 10 GE Ethernet interfaces as its uplink interfaces to implement wireless multi-media application.

10 3 Installation Preparations This chapter describes the preparations for installing WA series WLAN access points, including the preparation of installation tools and environment examination. The installation preparations for the H3C WA series access points depend on the installation environments (indoor or outdoor). For more information about the installation preparations of an AP model, see the installation guide or quick start of the AP. Installation Preparations Before installing your AP: Power on your AP, and connect it to an Ethernet. Check the corresponding LED status on your AP, and make sure that your AP works normally. Save the installation position, MAC address, and serial number of your AP, to facilitate the management and maintenance of APs by administrators. Determine whether installation accessories (for example, or power adapter) are needed according to the installation position and power supply mode of your AP. Order them in advance because some installation accessories are not shipped with your AP, and you need to purchase them yourself. Preparing Installation Tools When installing the AP, you may need the tools listed in Table 3-1. Choose the appropriate tools according to the installation environment. Table 3-1 List of installation tools Type of tool Indoor installation outdoor installation General tools Special tools 1-meter-long rulers, marking pens, knives, a percussion drill with appropriate bits, screw driver, and adjustable spanner Cable strippers, crimping pliers, and RJ-45 crimping pliers Digging tool, adjustable spanner, vices, and screw driver Cable stripper, crimping pliers, RJ-45 crimping pliers, waterproof tape, and fiber fusion splicer Auxiliary tools Ladders and rubber hammers Ladders 3-1

11 If you install the AP on a desk, none of the above tools is required. If you install the AP on top of or under eave of a building, no digging tool is required. Examining the Installation Site Before installation, examine the installation site to make sure that the AP will work in a good environment. You can examine the installation site from the following three aspects. Installation Site Selection Keep the AP away from places that are susceptible to high temperature, dust, inflammable, explosive, electromagnetic interference (high power radar, radio station, and transformer), unstable voltage, heavy vibration, or loud noise. The installation site should be dry, without any leakage, dripping, or dew. The AP should be at least 500 m (0.31 mi) away from the seaside and should not face the direction of sea wind. In engineering design, the site should be selected according to the network planning and technical requirements of communications equipment, as well as the considerations such as climate, hydrology, geology, earthquake, electric power, and transportation. Temperature and Humidity Requirements The temperature and humidity requirements depend on your AP model. For more information, see the installation guide or quick start of your AP. Power Supply The power supply mode depends on your AP model. For more information, see the installation guide or quick start of your AP. Grounding and Lightning Protection Table 3-2 Grounding and lightning protection requirements SN Item Requirements 1 Grounding resistance The earth resistance is usually required to be less than 5 ohms, and less than 10 ohms in an area with less than 20 thunderstorm days a year. If a piece of angle steel is buried as the earthing conductor, the earth resistance is required to be less than 10 ohms. In an area with a higher earth resistance, reduce the earth resistance by using brine or resistance reducing agent around the earthing conductor. The top of the earthing conductor should be at least 0.7 m (2.30 ft) away from the ground surface. In cold areas, the earthing conductor should be buried below the frozen soil layer. 3-2

12 SN Item Requirements 2 3 Device protection ground (PGND) Grounding lead-in If a grounding strip is available, connect the yellow and green ground cable of the AP to the grounding strip. If you need to make a grounding cable, the cable should be with a cross-section area of at least 6 mm 2 (0.24 in 2 ) and a length of no longer than 3 m (9.84 ft). If no grounding strip is available, bury a piece of angle steel/steel tube at least 0.5 m (1.64 ft) long in the earth to serve as the earthing conductor. In the case of a piece of angle steel, the size should be at least 50 mm 50 mm 5 mm (1.97 in in in.); in the case of a piece of steel tube, it must be zinc-plated and have a wall thickness of at least 3.5 mm (0.14 in.). Weld the yellow and green ground cable of the AP onto the earthing conductor and use anti-erosion treatment on the welding joint. The grounding cable should be as short as possible and must not be coiled. Ensure that the grounding points of all the lightning arresters of the AP and the peer device of the AP are well grounded. A grounding lead-in is a metal conductor connecting a grounding net and a grounding strip. The grounding cable of the AP should be connected to the grounding strip. The grounding lead-in must be 30 m (98.43 ft) or shorter. A piece of zinc-coated flat steel with a cross-section area of 40 4 mm ( in) or 50 5 mm ( in) is recommended. Connect the grounding strip and the grounding lead-in of the AP through the yellow and green ground cable with an area of 35 mm 2 (1.38 in.), or weld them directly. Use anti-erosion treatment on the welding joint. 4 5 Power grounding (AC) Lightning arrester 6 Feeder 7 Outdoor lightning arrester Use a power cord with a protective earth (PE). Do not use a power cord with only an L line and an N line. The neutral line of the power cord should not be connected with the PGND of other communications equipment. The L and N lines cannot be connected In plain areas, the protection angle of the lightning rod should be less than 45 degrees. In mountainous areas or lightning areas, the protection angle should be less than 30 degrees. The lightning protection grounding (for example, the grounding of the lightning rod) should be connected to the earthing conductor of the equipment room. The antenna support is already prepared according to the design requirements. A feeder lightning rod is already installed and grounded according to the design requirements. Power lightning arrester, port lightning protector, and feeder lightning arrester are recommended for outdoor installations. The power lightning arrester and the feeder lightning arrester should be near the AP, and the network interface lightning arrester should be near the peer device of the AP. The network interface lightning arrester should be installed where the network cable is just led out of the room. 8 Network cable Use a shielded twisted pair cables for an AP used outdoors. Ensure that the devices at the two ends of the cable are well grounded. After you have completed the preparations, you can start installing the AP. 3-3

13 4 Installing an AP You can directly place an indoor model (including the enhanced model) on a desk. The rubber feet on the bottom of the AP help you to place it horizontally. Or you can fix it onto a wall, a ceiling, or a lifting pole by using the wall-mounting bracket. Support for the installation method depends on your AP model. For more information, see the installation guide or quick start of your AP. Some installation accessories (for example, wall-mounting brackets) are not shipped with your AP. Determine whether to order them as needed. 4-1

14 5 Logging In to an AP Before logging in to an AP, power on the AP and connect it to a network. For more information, see Powering on the AP and Connecting It to a Network. When an AP works in the fit AP mode, you cannot directly log in to and manage it, but you can control it through an access controller or a unified switch associated with it. You can use any of the following methods to log in to a WA series WLAN access point working in the fat AP mode: Logging in through the console port Logging in through telnet Logging in through SSH Logging in through web-based network management system Logging in through NMS Powering on the AP and Connecting It to a Network After installing the AP, perform the following steps before logging in to the AP. Step1 the AP and connect it to an Ethernet. For how to connect the power supply and connect your AP to a network, see the installation guide or quick start of the AP. Step2 Check the LEDs on the AP. 1) Power LED When the AP is powered on, the power LED is steady on. If the power LED is not on, it is possibly because the AP is not powered on. 2) Ethernet LED If the Ethernet LED is steady on, the AP is connected to the Ethernet. If the Ethernet LED is blinking, the AP is connected to the Ethernet, and data is being transmitted and received. For the description of the LEDs on the AP, see the installation guide or quick start of the AP. 5-1

Specify the current domain to be in the active state. Disable the idle-cut function for the current ISP domain. Disable the location function of the self-service server. system is the default user group. You cannot delete the default user group but you can modify its configuration. The default configuration of the local user is as follows: The username is admin. The password is h3capadmin, case sensitive. The user level is 3 (manage level). The service type is telnet. The default a/b/g settings are as shown on the left column. The default rates depend on your AP model. By default, service template 1 with the authentication mode open system and SSID H3C is configured on the AP. The interface type supported by the AP. By default, the default IP address of VLAN-interface 1 is , and the subnet mask is The interface type supported by the AP. By default, WLAN-BSS32 is a hybrid port, and removes VLAN tags before forwarding packets from VLAN 1. By default, service template 1 is associated with radio interface WLAN BSS 32. The AP loads the configuration file with extension.xml after startup. The AP supports console and VTY user interfaces. By default, the authentication mode for VTY login is AAA. Besides the default configurations, you need to perform the following configurations to use a fat AP in your network: Specifying an IP Address for an AP Configuring WLAN Service Saving the Current Configuration 6-3

19 Specifying an IP Address for an AP Follow these steps to specify an IP address for the AP: To do Use the command Remarks Enter system view system-view Create VLANs vlan vlan-id1 [ to vlan-id2 ] Optional Using this command can create multiple VLANs in batches. Create a VLAN interface and enter VLAN interface view Assign an IP address to the VLAN interface Configure the description of the current VLAN Bring up the VLAN interface interface vlan-interface vlan-interface-id ip address ip-address { mask mask-length } description text undo shutdown Required If the VLAN interface already exists, you enter its view directly. If the VLAN interface does not exist, you need to create a VLAN and then enter VLAN interface view. Required IP address is assigned to VLAN-interface 1 by default. No IP address is configured for other VLAN interfaces. Optional VLAN interface name is used by default, for example, Vlan-interface1 Interface. Optional By default, a VLAN interface is in the up state. In this case, the VLAN interface is up so long as one port in the VLAN is up and goes down if all ports in the VLAN go down. An administratively shut down VLAN interface however will be in the down state until you bring it up, regardless of how the state of the ports in the VLAN changes. Configuring WLAN Service WLAN service configuration includes WLAN global configuration, country code, service template, and radio configuration. Follow these steps to configure WLAN service: To do Use the command Remarks Enter system view system-view Configure global WLAN parameters Specifies the time for which the link between AP and client ( power-save or awake ) can be idle Configure the keep alive timeout interval for the device Enable the fat AP to respond to the probe requests with the SSID null sent by the client wlan client idle-timeout interval wlan client keep-alive interval wlan broadcast-probe reply Optional By default, the idle timeout interval is 3600 seconds. Optional By default, keep alive function is disabled. Optional. By default,. the fat AP respond the probe requests with the SSID null sent by the client. 6-4

20 To do Use the command Remarks Specifying the Country Code Specify the country code Configuring a Service Template Create a WLAN service template. Disable the advertising of SSID in beacon frames Specify the maximum number of associated clients in a BSS Enable the authentication method Enable the service template Configuring the Radio of an AP Enter radio interface view Specify a radio type for the radio Map a service template to the current radio Specify a channel number for the radio wlan country-code code wlan service-template service-template-number { clear crypto } beacon ssid-hide client max-count max-number authentication-method { open-system shared-key } service-template enable interface wlan-radio interface-number radio-type { dot11a dot11an dot11b dot11g dot11gn } service-template service-template-number interface wlan-bss interface-number channel { channel-number auto } Required By default, the country code is CN. For more information about country code and country, see WLAN Service in the WLAN Command Reference in the H3C WA Series WLAN Access Points Command References. Required By default, a clear-type service-template has been configured. Optional By default, the SSID is advertised in the beacon frames. If the advertising of the SSID in beacon frames is disabled, the SSID must be configured for the clients to associate with the AP. Optional Required By default, open system authentication is enabled. If the current service template is of clear type, you can only enable open system authentication. If the current service template is of crypto type, you can enable open system or shared key authentication. Required By default, the service-template is disabled. Required Support for this command depends on your device model. Required Optional By default, auto mode is enabled. The working channel of a radio varies with country codes and radio types. The channel list depends on your device model. 6-5

21 To do Use the command Remarks Specify the maximum radio power max-power max-power Optional By default, the maximum radio power varies with country codes, channels, AP models, radio types and antenna types. If n is adopted, the maximum radio power also depends on the bandwidth mode. Specify the type of preamble preamble { long short } Optional By default, the short preamble is supported. Only b/g supports this configuration. Saving the Current Configuration You can modify the configuration on your device at the CLI. To use the modified configuration for the next startup, you must save it (using the save command) to the configuration file. You can save the configuration in either of the following two modes: Fast saving mode: Fast saving mode is implemented by using the save command without providing the safely keyword. The mode saves the file quickly but is likely to lose the existing configuration file if the device reboots or the power fails during the process. Safe mode. Safe mode is implemented by using the save command with the safely keyword. The mode saves the file more slowly that the fast saving mode but can retain the configuration file on the device even if the device reboots or the power fails during the process. The fast saving mode is suitable for environments where power supply is stable. The safe mode, however, is preferred in environments where stable power supply is unavailable or remote maintenance is involved. Follow a step below to save the current configuration: To do Use the command Remarks Save the current configuration to the specified file, but the configuration file is not set as the file to be used at the next startup Save the current configuration to the root directory of the storage medium and specify the file as the startup configuration file to be used at the next system startup up save file-url save [ safely ] [ backup main ] Required Use either command Available in any view 6-6

22 The configuration file must be with extension.cfg For the device that supports the main keyword, the execution of the save [ safely ] and save [ safely ] main commands has the same effect: The system saves the current configuration and specifies the configuration file as the main startup configuration file to be used at the next system startup. During the execution of the save [ backup main ] command, the startup configuration file to be used at the next system startup may be lost if the device reboots or the power supply fails. In this case, the device boots with the null configuration, and after the device reboots, you need to re-specify a startup configuration file for the next system startup 6-7

23 7 Software Maintenance The terminal output information may vary on your AP model. The configurations made on the WA2200 series throughout this chapter apply to WLAN APs. For the software maintenance process, see the specific configuration examples. Introduction Files Managed by the AP BootWare program file The BootWare program file is used by the AP to boot the applications; it is stored in the Flash of the device. The complete BootWare program file consists of the basic section and the extended section. Application files The AP provides one type of application file for device boot: main application file, which is stored in the Flash. Two main application files can exist in the AP as it supports fit and fat. For example, two main application files exist on a WA2200: WA2200_fit.bin or WA2200_fat.bin. When the AP works in the fat AP mode, you can use the boot-loader file file-url { main backup } command to specify either of them as the main application file. Configuration files With a file extension of.cfg, the configuration files contain the configuration information of the AP. Typically, the default configuration file is written into the Flash before the AP is delivered. The factory default configuration file is startup.cfg. Software Maintenance Approaches You can maintain the AP software in the following four ways: Upgrading the application files using the XMODEM protocol through a serial port Upgrading application files by using TFTP or FTP at the CLI. Upgrading application files through the web interface. Upgrading the application files automatically through an AC or a US (applicable to the fit mode only) 7-1

24 The WA series APs support upgrading the BootWare and application files of a specific version through upgrade package. Thus you do not need to upgrade the BootWare program separately. Figure 7-1 Software upgrade flowchart Start Comware application Uppgrade Comware? No Yes Select correct Comware application Select an upgrade method Load Comware through the network interface Auto upgrade through AC management (for fit mode only) Upgrade through the web interface Upgrade with XMODEM Upgrade with TFTP Upgrade at the CLI Upgrade with FTP Implement upgrade End BootWare Menus BootWare Main Menu Upon power-on or reboot of the AP, the console terminal connected with the AP displays the following information: System is starting...

The factory default configuration enables you to use all the basic functions upon AP power-on. If you perform configurations and save the configurations on the AP, the AP uses the configuration file you have saved for next startup. If you remove the current configuration file, namely, no configuration file exists on the AP, the AP starts with the factory default configuration upon next startup. If you disable the AP from booting with the default configuration (see Removing the Factory Default Configuration), it boots with null configuration. The filename you specified when saving the configuration file is used as the configuration filename for next startup. This startup mode is prior to the startup with the factory default configuration. If no configuration file exists on the Flash of the AP, it boots with the factory default configuration. The factory default configuration is set by the vendor of the AP, and you cannot modify it. Factory Default Configuration of a Fat AP For the factory default configuration of a fat AP, see Configuring Basic Functions for an AP Operating in Fat Mode. A fit AP has zero configuration. All the configuration and management are performed by ACs or USs. Removing the Factory Default Configuration Upon AP boot, when the prompt Press Ctrl+B to enter extended boot menu... appears, press Ctrl+B.

Fit/Fat Working Mode Switching The AP can work in the fat mode, or cooperate with an AC or a US to work in the fit mode, and it can switch between the fit mode and the fat mode. Before working mode switching, identify the current working mode of the AP to determine whether it needs to perform a mode switching. Switching the Working Mode Through the BootWare Menu The working mode of the AP depends on the main application file in its Flash. If the main application file in the Flash is XXXX_fit.bin, the AP works in the fit mode; if the main application file in the Flash is XXXX_fat.bin, the AP works in the fat mode. When setting the working mode through the BootWare menu, you need to judge whether the main application file in the Flash is consistent with the working mode. During the upgrade process, do not change the main application filename, thus to avoid inconsistency of the working mode that has been configured and the current working mode.

For more information about the rename command, see SSH2.0 in the Security Command Reference in the H3C WA Series WLAN Access Points Command References. Switching the Working Mode at the CLI Set the working mode to fit AP To set the working mode of the AP working in the fat mode to the fit mode, use the boot-loader file file-url { main backup } command: On a WA2200 series: <Sysname>boot-loader file wa2200_fit.bin main This command will set the boot file. Continue? [Y/N]:y The specified file will be used as the main boot file at the next reboot on slot 1! 7-10

33 Fat and fit files cannot be stored in the Flash at the same time due to the space limitation of the Flash of the AP. Therefore, before you switch the working mode of the AP from fat AP to fit AP, you need to delete the fat file in the Flash to release the space of the Flash. When deleting the fat file, use the delete /unreserved plus name of the file to be deleted in user view (you can view the file name using the dir command in user view). Then, use TFTP to download the fit file, and set the working mode of the AP to the fit AP mode. When you switch the working mode of the AP at the CLI, the configuration file used for next startup is set to null. After you reboot the AP, the system starts with the factory default configuration of the current mode. Set the working mode to fat AP To set the working mode of the AP working in the fit AP mode to the fat AP mode, you can execute the wlan ap-execute ap-name conversion-to-fatap command on the AC or US: For example, set the working mode of ap1_003 to the fat AP mode: <Sysname> system-view [Sysname] wlan ap excute ap1_003 concersion-to-fatap After setting the working mode of the AP at the CLI, you need to restart the AP to make your configuration take effect. You can use the wlan ap-execute ap-name conversion-to-fatap command on an AC or a US to set the working mode of the AP to fat AP only in the case that the AP running as a fit AP is associated with the AC or US and the fat AP version is stored in the Flash. Upgrading Applications Through the Serial Port XMODEM Overview To upgrade applications through a serial port, use the XMODEM protocol. XMODEM is a file transfer protocol that is widely used because of its simplicity and good performance. XMODEM transfers files via serial ports. It supports two types of data packets (128 bytes and 1 KB), two check methods (checksum and CRC), and error packet retransmission mechanism (generally the maximum number of transmission attempts is ten). The XMODEM transmission procedure is completed by the cooperation of a receiving program and a sending program. The receiving program sends a negotiation character to negotiate a check method. After the negotiation, the sending program starts to send data packets. Upon receiving a complete packet, the receiving program checks the packet using the agreed method. If the check succeeds, the receiving program sends an ACK character and the sending program proceeds to send the next packet. 7-11

34 If the check fails, the receiving program sends a NAK character and the sending program retransmits the packet. Modifying Serial Communication Parameters In actual applications, you need to make the serial interface baud rate higher to save updating time or make it lower to guarantee transmission reliability. This section introduces how to adjust the serial interface baud rate. Enter the BootWare main menu. For the WA2200 series, WA2600 enhanced APs, and WA2600 outdoor APs, select 2 to enter the serial interface submenu, and then select 3 from the submenu to modify the baud rate. For the WA2600 series indoor APs, select 2 to enter the serial interface submenu, and then select 5 from the submenu to modify the baud rate. ===============================<BAUDRATE SET>=============================== Note:'*'indicates the current baudrate Change The HyperTerminal's Baudrate Accordingly <Baudrate Avaliable> <1> 9600(Default)* <2> <3> <4> <5> <0> Exit ============================================================================ Enter your choice(0-5): Select an appropriate baud rate. For example, select 5 for bps. The following information appears: Baudrate has been changed to bps. Please change the terminal's baudrate to bps, press ENTER when ready. Now that the serial interface baud rate of the AP has been changed to 115,200 bps while that of the terminal is still 9,600 bps, the AP and the terminal cannot communicate with each other. Change the baud rate to 115,200 bps in HyperTerminal. Step1 Disconnect the terminal connection in HyperTerminal, as shown below: Figure 7-2 Disconnect the terminal connection Step2 Choose File > Properties. In the Properties dialog box, click Configure and select 115,200 in the Bits per second drop-down list box. 7-12

35 Figure 7-3 Modify the baud rate Step3 Select Call > Call to reestablish the connection. Figure 7-4 Reconnect the call Then, press Enter in the serial interface submenu. After downloading files with a changed baud rate, timely change the baud rate back to 9,600 bps in HyperTerminal to ensure the normal display on the console screen when the system boots or reboots. Upgrading an Application Upgrading an application through the serial port is implemented in the submenu of the serial port. Enter the BootWare main menu, and select 2 to enter the serial port submenu. For more information about this menu, see Serial interface submenu. Upgrade main application wa2200_fat.bin: 7-13

36 Step1 Change the communication baud rate by referring to Modifying Serial Communication Parameters. Select 2 from the serial interface submenu. The following prompt appears: Please Start To Transfer File, Press <Ctrl+C> To Exit. Waiting...CCCCCCCCCCCCCCCCCCCC Step2 Select Transfer > Send file in the HyperTerminal window. The following dialog box appears: Figure 7-5 Send File dialog box Step3 Click Browse to select the application file to be downloaded, and select Xmodem from the Protocol drop-down list. Then click Send. The following dialog box appears: Figure 7-6 Download the file using XMODEM Upon successful download, the system displays the following information: Download successfully! bytes downloaded! The system prompts you to name the application downloaded to the current storage medium: Input the File Name: 1) If the input file name is different from the existing one, the downloaded application is given this name, for example: 7-14

37 Input the File Name:wa2200_fat.bin Updating File flash:/ wa2200_fat.bin done! Return to the BootWare main menu, and enter the file control submenu to set the application as the main application. The system will boot with this application at the next boot. For more information about how to set the main application, see Set the selected file as the main application program (loaded when the system starts).. 2) If the input file name is the same as the existing one, the system prompts: The file is exist,will you recover it? [Y/N] If you select Y, the system overwrites the original application, and the AP boots with the new application at the next boot. If you select N, the system prompts: Cancel to overwrite the file. Failed! The system cancels overwriting the existing application, and the upgrade fails. The size of an application is typically big. Even if you change the baud rate to bps, the upgrade process takes about 30 minutes. Therefore, it is recommended that you upgrade an application through an Ethernet. Upgrading Applications Through TFTP at the CLI The Trivial File Transfer Protocol (TFTP) is a TCP/IP protocol used for file transfer between client and server. It provides a simple and low-overhead file transfer service. TFTP provides unreliable data transfer over UDP and does not provide any access authorization and authentication mechanism. It employs the timeout retransmission method to implement best-effort delivery of data. Compared with FTP, TFTP has a much smaller software size. Setting Up an Upgrade Environment Set up an upgrade environment as shown in Figure 7-7 and Figure 7-8. Figure 7-7 Set up an upgrade environment 7-15

In the example, the IP address of VLAN-interface 1 of the AP is , and that of the PC is As shown in Figure 7-8, AP serves as the TFTP client, and the PC serves as the TFTP server. Connect AP and PC through a PoE switch. In the example, the IP address of VLAN-interface 1 of AP is , and that of the PC is Enable TFTP Server on the PC and set the path where the application file is stored. The TFTP server software is not provided with the AP. Make sure that it is available by yourself. Displaying the System Files and Available Space of the Storage Medium Use the dir command on the console terminal to view the files contained in the current file system and the available space. <Sysname>dir Directory of flash:/ 0 -rw Apr :04:49 wa2200_fat.bin 1 -rw Apr :01:37 startup.cfg 2 -rw Apr :01:27 config.cwmp 3 -rw- 33 Apr :01:27 system.xml KB total (7234 KB free) <Sysname> Table 7-4 dir command output description Field Description Directory of flash:/ rw The current directory name r: The file or directory is readable. w: The file or directory is writable KB total (7234 KB free) If the available space of the flash is not enough, the upgrade fails. 7-16

39 Upgrading an Application. You can download an application from a TFTP server to your AP, and upgrade the original application with the new one. The configuration takes effect at the next boot of the AP. # Download application file wa2200_fat.bin from the PC to the AP. <Sysname>tftp get wa2200_fat.bin The file wa2200_fat.bin exists.

If the file name already exists on the AP, the system prompts whether to overwrite the file on the AP. You need to choose Y or N for confirmation. For information about the tftp command, see FTP and TFTP in the Fundamentals Command Reference in the H3C WA Series WLAN Access Points Command References. You can update a configuration file in the way you update an application file. A configuration file can be modified by a text editor. You can modify a configuration file and then download the modified configuration file to the AP, and the modification takes effect after the AP reboots. Backing Up an Application To back up an application, you can upload the application from your AP to a TFTP server. # Upload application file wa2200_fat.bin on the AP to the PC, and save it as wa2200_fat.bin. <H3C> tftp put wa2200_fat.bin wa2200_fat.bin File will be transferred in binary mode Sending file to remote TFTP server. Please wait... TFTP: bytes sent in 13 second(s). File uploaded successfully. 7-17

40 When you back up an application, if the file name already exists on the AP, the system does not output any information, but directly overwrites the existing file. For information about the tftp command, see FTP and TFTP in the Fundamentals Command Reference in the H3C WA Series WLAN Access Points Command References. To back up a configuration file, use the same method. Table 7-5 Output description of commands for application upgrade and backup when the AP serves as a TFTP client Output tftp get wa2200_fat.bin The file wa2200_fat.bin exists. Overwrite it?

Prompt you whether to overwrite the existing file. The file is downloaded and upgraded. Upload the file from the AP to the TFTP server. The file is uploaded and backed up successfully. Upgrading the Applications Through FTP at the CLI When the application file is large, you can also upgrade it using FTP to save upgrade and maintenance time. As an application layer protocol in the TCP/IP suite, the File Transfer Protocol (FTP) is mainly used for file transfer between remote hosts. FTP provides reliable, connection-oriented data transfer service over TCP. Compared with TFTP, the FTP software is much bigger. The AP can only serve as the FTP client, rather the FTP server to provide FTP services.
