***** QUICK START FOR THE RoamAbout CONFIGURATOR APPLICATION ***** The RoamAbout Configurator has been developed to provide easy setup and software management of Digital RoamAbout wireless networks. This application has been designed SPECIFICALLY for RoamAbout wireless networks and can assist a user in two roles: as a setup/configuration tool for new Access Points, and as a management tool to assist the on-going management and support of Digital RoamAbout wireless networks. As such it includes a number of interesting features to make your RoamAbout wireless network easier to configure and manage, and even to allow it to perform better. FEATURES INCLUDE: - The ability to make parameters changes on multiple RoamAbout Access Points in a wireless network with a single command. - Built in integrity checking for many wireless parameter changes. This will warn the user if a common wireless network management mistakes is about to be made, or if the operation requested is unusual and usually not recommended. - Integrity checking of an existing wireless network configuration for consistent settings and common management errors. - Improved wireless network performance thru easy packet filtering and Digital recommended filter settings. - Integration with a BOOTP/TFTP application for simple Access Point software upgrades, also called flash upgrades. - The ability to manage an Access Point remotely, without a console. - Support for both Direct Sequence (DS) and Frequency Hopping (FH) technology. INSTALLATION The Configurator is a self installing product. It will add a Program Group called "RoamAbout". For full functionality, all RoamAbout Access Points should be at version V2.4 or greater. INTRODUCTION TO THE CONFIGURATOR MAIN WINDOW The main window of the configurator is broken into left and right half. The right half contains buttons which are used to invoke groups of management commands, while the left half is used to select one or more Access Points to receive a particular command. The left side of the main application window contains the Access Point managed list box. This is used to display a "managed list" of Access Points that the configurator knows about, and can therefore manage. Before a user can manage an Access Point (AP) with the configurator, the AP must be added to the managed list. Before discussing how this is done, a quick description of what should be in a managed list follows. It is recommended that all APs in a wireless domain be included in a managed list, and that different domains be represented by different lists. The managed list can be viewed as window into a database of information on a particular wireless domain. Wireless networks with multiple domains should have multiple managed lists. This easy to do, as managed lists can be saved and retrieved in the form of configuration files. (.cfg files) RoamAbout Access Points are added to the appropriate managed list in one of two scenarios. These two scenarios show the double role that the configurator has been designed to play: to be a setup tool for new Access Points, and to be a management tool for operating wireless networks. In the first scenario, the configurator is used to assist a user in the initial setup of an Access Point right out-of-the-box. As part of this initial setup procedure, the new Access Point is automatically added to the managed list of the configurator. In the second scenario, the configurator is incorporated into an existing wireless network. Since the Access Points are already setup, all that is needed is to make the configurator aware of them. In both scenarios, the "Setup/Add Access Point" button can be used to perform the desired action. SETTING UP A NEW ACCESS POINT When setting up a new Access Point, the first operation to be performed is to insert a PC Card and attach an antenna as specified in the User's Guide. The Access Point is then operational and the management settings are set to the default. In order to modify any settings the first step is often to load an IP address so that SNMP management communication can take place. The easiest way for this to occur is thru the console, menu option #8. However, for installations that do not wish to use the console, the IP address can be loaded on the Access Point with the configurator. To use the configurator you will need to know the hardware (MAC) address of the wired port from the front panel of the AP, and be able to reset the power to the Access Point when required. To set up an Access Point with the configurator, press the "Setup/Add New Access Point" button on the top right portion of the main window. The first operation is to ask you if you need to load an IP address. Answer appropriately. The procedure then walks the user through the Identification and Wireless Parameters management command dialog boxes to allow the user to minimally customize the Access Point. It is highly recommended that all fields in the "Identification" dialog be set to appropriate values, and that the fields in the Wireless Parameters dialog be set as needed. For DS technologies, this is usually the Domain ID, Beacon Key, Station Name settings, and DES encryption key (for DES equipped units); for the FH technologies this is often the Domain, Security ID, and Master Name settings. MANAGEMENT COMMAND DIALOG BOXES After all Access Points in the wireless domain have been represented in the managed list, the right half of the main window contains buttons that are used to invoke dialog boxes which can perform groups of management operations. At the top of each dialog is a combo box which contains a listing of all Access Points currently selected in the managed list. These dialogs have been designed to perform two purposes. They can display data (SNMP GETs) from a single AP at a time, and they can be used to modify data (SNMP SETs) on one or more Access Points at a time. When viewing data, the Access Point to which the displayed data applies is shown in the combo box at the top of the dialog box. When setting data, the default targets for set commands will be all selected APs in the managed list to allow for easy group sets. Access Points that are selected for sets are confirmed before proceeding. VIEWING DATA FROM ACCESS POINTS The easiest way to view Access Point data is to select an AP in the managed list box on the left half of the main window, and then press the button on the right half which corresponds to the information you are interested in to invoke the management dialogs. To view data from another AP, close the dialog box and repeat the process. An alternative method can be used to minimize the opening and closing of the dialog boxes. In this case, select some or all of the APs in the managed list and then choose a management function button to invoke a dialog. In order to view data from a particular AP, simply select that AP in the combo box at the top of the particular management dialog. The combo box is loaded with the APs selected in the managed list when the dialog box is invoked. SETTING DATA ON SINGLE OR A GROUP OF ACCESS POINTS By specifying a group of Access Points and then invoking a dialog, you have followed the first step needed to perform a powerful function, group sets. With group sets, the changes you make to data in the dialog can be propagated to any number of Access Points with a few keystrokes. After modifying data in a management function dialog, the data field turns red. This is to make it clear which pieces of data will be modified with a subsequent set command. Editing data also causes the OK button to become active. This is the dialog button which is to be pressed to commit to the changes made in the dialog. (Cancel will exit the dialog without making any changes.) If a single AP has been selected in the managed list, the specified changes are invoked right away to that single Access Point. If multiple APs have been selected (including all), a group set command will be performed on all Access Points selected. However, before the changes occur a selection box will be appear asking the user to confirm the group of APs which are to be modified. Access Points can be removed from the group set list at this point by deselecting them. Pressing OK at this point causes the configurator to issue a set command on all red data items to all selected APs. The group set functionality was designed to easily change domain-wide parameters such as Domain ID and Beacon Key for Direct Sequence technology, or Domain and Security ID for Frequency Hopping technology. Protocol filters are another value which is often set on a domain-wide basis, and this performance enhancing action is easily accomplished as well. INTEGRITY CHECKING AND WARNINGS When many wireless parameters are modified, the configurator has logic built into it which will warn a user if they are performing an operation which may be a common mistake for a wireless network manager. This warning can be overridden in all cases, but these warnings are designed to help an inexperienced wireless network manager set the network up in a consistent way. In addition, certain parameters in the wireless network can be tested for consistency at any time in an operating wireless domain. These checks are performed by making a selection under the Integrity main menu choice. Wireless network parameters, operating modes, and firmware revisions are some of the values that can be integrity/consistency checked at any time. Note that the subset of Access Points that are included in an integrity check are only those that are selected in the AP managed list box. Therefore it is recommended that the "Select All" button be pressed to select all Access Points in a domain before running the check(s). ACCESS POINT SOFTWARE (FLASH) UPGRADES The software running inside the Access Point can be easily upgraded with the configurator. In order to have your Access Point operating at its best, it is recommended that an AP be running the latest revision of the AP software. If you feel that the Access Point is not running as intended, the first step in the problem resolution should be to load the latest AP firmware. Should you wish to load the Access Point with an upgraded version of the firmware, it is suggested that you copy the .bin file to the same directory as the configurator. As part of the flash upgrade, the configurator will ask for the location of the .bin file, and the default location will be the configurator directory. After obtaining this information, a BOOTP/TFTP loader called the NetRider Loader will be launched by the configurator, and a flash upgrade request will be made to a single Access Point. Some things to note here. First, a flash upgrade command, or a reset command of any sort cannot be made to a group of Access Points. Second, be aware that a major version flash upgrade may cause the loss of the IP address on the Access Point, so the IP address may have to be reloaded, and management communications with that Access Point will be lost in the meantime. Third, you will see the flash load happen on the UI of the NetRider Loader. After this happens, the Access Point will still need to process the new software, and will be unavailable for a few minutes afterwards. The easiest way to know this has completed is to look for normal flashing of the front panel lights. Until this happens, trying to read data from the Access Point with the configurator will fail because the AP is not responding. CONFIGURATION FILES AND THE SELECTION MENU The "managed list" is a term that has been assigned to a domain of Access Points being managed by the configurator. These APs are listed in the managed list box on the left half of the main window. These managed lists can be saved and retrieved in the form of configuration files. To save a list of Access Points to a configuration file, use the standard File "Save" or "Save As" menu choices. The standard file open is used to read a managed list configuration into the configurator. As part of using the managed list, Access Points are added and occasionally deleted from the list. One method of adding an Access Point to the managed list was described in the section entitled "Setting Up a New Access Point". A second method of adding an AP is available under the selection menu. By choosing Selection/Add and specifying an IP address when prompted, an Access Point is added to the managed list. It is recommended that this method only be used on preconfigured APs, because the configurator uses Identification information it gets from the Access Point to create an entry in the managed list. If this information is still blank because it has been configured before, the list entry will be confusing to read. As another part of controlling the display characteristics of an entry in the managed list, the user has the ability to specify whether or not to show IP address and Location information as part of the entries in the list. It is recommended that the user enable the display of these parameters in the Selection menu as it helps in identification. OPTIONS The options selection in the configurator's main menu allows the user to customize the SNMP R/W community string, and the timeout/retry parameters for SNMP commands. In addition, the toolbar and status bar can be selected or deselected as part of the options menu. When modifying a community string, there are typically one of two primary scenarios in mind. The first is the case where the Access Points already have a user specified community string, and the configurator must use that community string to obtain SNMP information. In this case, the R/W community string is modified in the community string dialog box, and the "Change community string on AP also" check box is left blank. The second scenario occurs when a user wishes to change the R/W community string on an Access Point itself. In that case, the user makes a change to the R/W Community field and checks the "Change community string on AP also" check box. This causes a change command to be sent to the AP, and the configurator also changes its internal community string to keep in sync with the Access Point.
