[. . . ] · If you selected ASCII as your key type, enter any combination of 0-9, a-z, and A-Z. · If you selected HEX as your key type, enter hexadecimal digits (any combination of 0-9 and a-f or A-F). These are the RC4 encryption keys shared with the stations using the access point. Example of Configuring a WDS Link When using WDS, be sure to configure WDS settings on both access points on the WDS link. For example, to create a WDS link between the pair of access points MyAP1 and MyAP2 do the following: 1. Open the Web User Interface for MyAP1 by entering the IP address for MyAP1 as a URL in the Web browser address bar in the following form: http://IPAddressOfAccessPoint where IPAddressOfAccessPoint is the address of MyAP1. Navigate to the WDS tab on MyAP1 Web User Interface. Wireless Distribution System - 158 Professional Access Point Administrator Guide The MAC address for MyAP1 (the access point you are currently viewing) will appear as the Local Address at the top of the page. Start by entering the MAC address for MyAP2 as the Remote Address, and fill in the rest of the fields to specify the network (guest or internal), security, and so on. Navigate to the radio settings on the Web User Interface (Advanced menu's Radio tab) to verify or set the mode and the radio channel on which you want MyAP1 to broadcast. Remember that the two access points participating in the link, MyAP1 and MyAP2, must be set to the same mode and be transmitting on the same channel. For this example, suppose that you are using IEEE 802. 11b mode and broadcasting on Channel 6. (Choose Mode and Channel from the drop-down lists on the Radio tab. ) 5. Now repeat steps 1­4 for MyAP2: · · · · · Open the Web User Interface for MyAP2 by using MyAP2's IP address in a URL. Configure a WDS interface for data exchange with MyAP1, starting with the MAC address for MyAP1. Navigate to the radio settings for MyAP2 to verify that it is using the same mode and broadcasting on the same channel as MyAP1. Be sure to save the settings by clicking Update. Updating Settings To apply your changes, click Update. Wireless Distribution System - 159 Professional Access Point Administrator Guide Wireless Distribution System - 160 Professional Access Point Administrator Guide Time Protocol The Network Time Protocol (NTP) is an Internet standard protocol that synchronizes computer clock times on your network. NTP servers transmit Coordinated Universal Time (UTC, also known as Greenwich Mean Time) to their client systems. NTP sends periodic time requests to servers, using the returned time stamp to adjust its clock. The timestamp is used to indicate the date and time of each event in log messages. The following sections describe how to configure the Professional Access Point to use a specified NTP server: · · · Navigating to Time Protocol Settings Enabling and Disabling a Network Time Protocol (NTP) Server Updating Settings Navigating to Time Protocol Settings To enable an NTP server, click the Advanced menu's Time Protocol tab, and update the fields as described below. Time Protocol - 161 Professional Access Point Administrator Guide Enabling and Disabling a Network Time Protocol (NTP) Server To configure your access point to use a network time protocol (NTP) server, first enable the use of NTP, and then select the NTP server you want to use. (To shut down NTP service on the network, disable NTP on the access point. Time Protocol - 162 Professional Access Point Administrator Guide ) Field Network Time Protocol (NTP) Description NTP provides a way for the access point to obtain and maintain its time from a server on the network. Using an NTP server gives your access point the ability to provide the correct time of day in log messages and session information. (See http://www. ntp. org for more general information on NTP. ) Choose either to enable or to disable the use of a network time protocol (NTP) server: · Enabled · Disabled NTP Server If NTP is enabled, select the NTP server that you want to use. [. . . ] The Professional Access Point supports the configuration of a wireless VLAN. This technology is used on the access point for the virtual guest network feature. VPN A Virtual Private Network (VPN) is a network that uses the Internet to connect its nodes. It uses encryption and other mechanisms to ensure that only authorized users can access its nodes and that data cannot be intercepted. Glossary - 320 Professional Access Point Administrator Guide W WAN A Wide Area Network (WAN) is a communications network that spans a relatively large geographical area, extending over distances greater than one kilometer. A WAN is often connected through public networks, such as the telephone system. [. . . ]
