BW2251 User Guide v1.0 Nov. 2013 Page 37 of 187 Network | WAPI Certificate Upload WLAN Authentication and Privacy Infrastructure (WAPI) is a Chinese National Standard for Wireless LANs (GB 15629.11-2003), which was initiated to resolve the existing security loopholes (WEP) in WLAN international standard (ISO/IEC 8802-11). WAPI works by having a central Authentication Service Unit (ASU) which is known to both the wireless user and the access point and which acts as a central authority verifying both. The WAPI standard (draft JTC1/SC6/N14619) allows selection of the symmetric encryption algorithm, either AES or SMS4, which has been declassified in January 2006 and passed evaluation by independent experts. Figure 47 – WAPI certification upload ASU Cert – uploading the ASU certification AP Cert – uploading the AP certification Network | Tr069 Settings TR-069 is the Broadband Forum technical specification entitled CPE WAN Management Protocol(CWMP). It defines an application layer protocol for remote management of end-user devices. As a bidirectional SOAP/HTTP-based protocol, it provides the communication between customer-premises equipment(CPE) and Auto Configuration Servers(ACS server). It includes both a safe auto configuration and the control of other CPE management functions within an integrated framework. The protocol addressed the growing number of different internet access devices such as modems,routers,gateways,set-top-boxes,and VOIP-phones for the end users. The TR-069 standard was developed for automatic configuration of these devices with Auto Configuration Servers(ACS). configure the remote management through TR069 ACS server(eg:BROWAN DMS server) Figure 48 – TR-069 settings Click Edit button and the similar page will be appeared.

(AP mode or Bridge mode) Domain – show the regulatory domain Static Channel / Auto Channel – show the channel that the access point will use to transmit and receive information If DCA (Dynamic Channel Allocation) is enabled, this will show Auto Channel and its channel number is chosen in auto channel selection. If use static channel selection, this will show Static Channel and its channel number. DCA (Dynamic Channel Allocation) is useful feature to help choose the best channel automatically and reduce interference among many Access Points. Band – show the working bands on which the radio is working. wlan1:four bands listed: 2.4GHz(11g only) , 2.4GHz(11n HT20) , 2.4GHz(11n HT20/40plus), 2.4GHz(11n HT20/40minus) wlan2: four bands listed:5GHz(11a), 5GHz(11n HT20) , 5GHz(11n HT20/40plus), 5GHz(11n HT20/40minus) . By default, the HT20/40 is recommended. Tx Power – show the BW2251 transmission output power (without antenna gain) in dBm. RTS Threshold –the AP sends Request to Send(RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send(CTS) frame to acknowledge the right to begin transmission. The default value is 2347.[recommend]. Fragment Threshold –It specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the fragmentation threshold. Setting the fragmentation threshold too low may result in poor network performance. Only minor modifications of this value are recommended. The default value is 2347.[recommend] Beacon Interval –the Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the AP to synchronize the wireless network. DCA – Enable or Disable DCA service. DCA can help to choose the best working channel automatically. And static channel selection will be forbidden if DCA is enabled. DCA(Dynamic Channel Allocation) solution automatically select the optimal operational frequency channel when power up and periodically monitors the environment and adjusts for the best operational frequency channel. DCA threshold – specify the value (in minutes) of DCA threshold. This threshold is been used to judge if there is no wireless users connected during this time. And if yes, BW2251 will monitor the environment and adjust channel for the best operational one. If wireless network environment is stable which means auto channel selection needn’t do frequently, set a big value for DCA threshold to gain a stable wireless users’ connection. If wireless network environment changes continually, frequent auto channel selection is needed. So set a relative small value for DCA threshold to let channel change based on wireless environment.

Wireless | Advanced BW2251 supports Multiple BSSID (MBSSID) function. You can configure up to 16 BSSIDs on BW2251 and assign different configuration settings to each BSSID. For wireless users, they can think BW2251 as single AP with multi-service supporting, including different security policy, different VLAN ID, different authentication etc. All the BSSIDs are active at the same time that means client devices can associate to the access point for specific service. Use the Wireless | Advanced menu to configure properties related to Multiple BSSID, including configure SSID, Hidden SSID, VLAN, and Security for each SSID. You can define different MBSSID if you configure AP mode in Wireless | Basic menu. Each BSSID can have its own SSID. In this case, Multiple BSSID is the same with Multiple ESSID. Wireless users can think BW2251 as multiple virtual APs, each supporting different service, and connects one SSID for the special services.

BW2251 User Guide v1.0 Nov. 2013 Page 109 of 187 Radio – specify which wireless interface of BW2251 is shown. [wlan1(2.4G)/wlan2(5G)] Mode – show the radio operation mode. (AP mode or Bridge mode) Domain – show the regulatory domain Static Channel / Auto Channel – show the channel that the access point will use to transmit and receive information If DCA (Dynamic Channel Allocation) is enabled, this will show Auto Channel and its channel number is chosen in auto channel selection. If use static channel selection, this will show Static Channel and its channel number. DCA (Dynamic Channel Allocation) is useful feature to help choose the best channel automatically and reduce interference among many Access Points. Band – show the working bands on which the radio is working. wlan1:four bands listed: 2.4GHz(11g only) , 2.4GHz(11n HT20) , 2.4GHz(11n HT20/40plus), 2.4GHz(11n HT20/40minus) wlan2: four bands listed:5GHz(11a), 5GHz(11n HT20) , 5GHz(11n HT20/40plus), 5GHz(11n HT20/40minus) . By default, the HT20/40 is recommended. Tx Power – show the BW2251 transmission output power (without antenna gain) in dBm. RTS Threshold –the AP sends Request to Send(RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send(CTS) frame to acknowledge the right to begin transmission. The default value is 2347.[recommend]. Fragment Threshold –It specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the fragmentation threshold. Setting the fragmentation threshold too low may result in poor network performance. Only minor modifications of this value are recommended. The default value is 2347.[recommend] Beacon Interval –the Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the AP to synchronize the wireless network. DCA – Enable or Disable DCA service. DCA can help to choose the best working channel automatically. And static channel selection will be forbidden if DCA is enabled. DCA(Dynamic Channel Allocation) solution automatically select the optimal operational frequency channel when power up and periodically monitors the environment and adjusts for the best operational frequency channel. DCA threshold – specify the value (in minutes) of DCA threshold. This threshold is been used to judge if there is no wireless users connected during this time. And if yes, BW2251 will monitor the environment and adjust channel for the best operational one. If wireless network environment is stable which means auto channel selection needn’t do frequently, set a big value for DCA threshold to gain a stable wireless users’ connection. If wireless network environment changes continually, frequent auto channel selection is needed. So set a relative small value for DCA threshold to let channel change based on wireless environment.
BW2251 User Guide v1.0 Nov. 2013 Page 110 of 187 Wireless users’ will be kicked off when DCA is processing (new operational frequency channel takes effect). DCA optional channel – show the channels only in which auto channel selection (DCA) will be processed to reduce interference. Only when DCA is enabled, DCA threshold and DCA optional channel will be shown. Preamble – if your wireless device supports the short preamble and you are having trouble getting it to communicate with other 802.11b devices, make sure that it is set to use the long preamble. Auto: using long preamble when there are clients not supporting short preamble connected , otherwise using short preamble. The default is Auto.[recommend] Short: always using short preamble. Long: always using long preamble. Slot Time – show the slot time policy when working in 2.4GHz band. Auto: using long slot time when there are clients not supporting short slot time connected in, otherwise using short slot time. The Switching between long and short slot time is automatic.

AC sendsrequest toRADIUS8. RADIUS reply authenticated or not Figure 307 – Client Remote Authentication Scheme (1) The Client initiates (1) authentication process. AC intercepts any access to the Internet via HTTP and redirects the client to the welcome, or login URL on AC. In order to render the custom login screen HTML page, the AC must be configured to (2) fetch .XSL script from a remote server, which in this case is a Web Application Server (WAS), or have custom .XSL uploaded on the AC. There is the ability to enable caching of .XSL scripts (see: User | Pages), thus avoiding fetching of the same document every time a client requests authentication. The AC (3) uses .XSL script to render HTML output, which is done by feeding a XML document to a parsed and prepared for rendering .XSL script. The latter XML document contains all needed information for Web Application Server like user name, password (if one was entered), user IP address, MAC address and NAS-Id. Custom .XSL script must generate initial welcome/login screen so that it embeds all the needed information in a HTML FORM element as hidden elements and POST data not back to the AC, but to the Web Application Server (5). Thereafter the client communicates directly with the Web Application Server.
BW2251 User Guide v1.0 Nov. 2013 Page 168 of 187 When the Web Application server has all needed data from the client, it must try to authenticate (6) the client. Authentication is done by the RADIUS server but through the AC. At this step the shared secret is used to make the connection between the WAS and the AC. The AC re-sends the authentication request to the RADIUS server (7). Depending on the status, appropriate authentication status must be returned back to the WAS but through the AC (8). In step (9), the Web Application Server knows the client authentication status and reports success or failure back to the client. The Web Application Server (WAS) must be configured as a free site in the Walled Garden area. There is an ability to skip the rendering initial user pages from the .XSL. See the following scheme when the user initial request is redirected to the specified location. Scheme 2: The remote authentication method when client with proxy authentication request is re-directed to the external server (WAS): Client AC WAS RADIUS Server1. Initial Request 2. Replay with HTTP redirect 3. Direct client communication with WAS 4. Client sends his/her login and password 8. WAS reports client status: authenticated or not 5. WAS tries toauthenticateclient6. AC sendsrequest toRADIUS7. RADIUS replay authenticated or not Figure 308 – Client Remote Authentication Scheme (2) The initial client request (1) can be redirected to the specified location, as redirection URL on the Web Application server. In such case the client who wants to authenticate gets the redirection from AC (2). In other words the AC intercepts any access to the Internet via HTTP and redirects the client to the defined welcome, or login URL on WAS (also see: User | Pages). The further actions are the same as described in the Scheme 1 (Figure 307 – Client Remote Authentication Scheme (1)). The WAS location URL under welcome page redirect must be configured as a free site in the Walled Garden area. To define such redirection URL use the user | pages menu. Enable welcome page, set the redirect setting and specify the redirect location for such authentication process (also see: User | Pages).
