Overview MegaVision is a network management application. Its main function is managing a specific set of supported devices, however, it can discover and perform many functions with virtually any vendor SNMP or TCP/IP devices. It provides you with the consistent view of your whole network, helps with its configuration, monitoring and troubleshooting. This manual contains only generic MegaVision information, which is applicable to the whole system and all managed devices.
MegaVision Features MegaVision helps you to quickly configure the network. It detects network problems, provides device and port control, and offers real-time and historical graphical and statistical displays. Here is the list of main features applicable to both MegaVision Classic and MegaVision-WEB: • Rich user-friendly GUI full management for the supported family of products. • Ability to discover and monitor any vendor SNMP or TCP/IP compliant device.
Quick Start 1. Always reboot MS-Windows before installing MegaVision-WEB. Make sure that no other MegaVision version is running. 2. Install MegaVision-WEB by running "…/DISK1/setup.exe" from MegaVision-WEB CD or Installation Kit via "Start"/"Run" function of MS Windows. Follow instructions on the screen. This is a standard MS Windows installation. 3. After installation is completed start MegaVision via "Start"/"Programs"/"MegaVision WEB"/"MegaVision WEB" menu item of MS Windows.
Please, note the "password" is the same "password" which is used in the MegaVision-WEB Login screen. By default, after installation the supervisor's password is Empty String, so you may just press the "Login" button. 10. IMPORTANT TROBLESHOOTING INFO!!! If you are running Netscape, you do not need any additional configuration.
e. Close the Internet Explorer and enter it again. You should not see this error any more. 11. IMPORTANT TROBLESHOOTING INFO!!! If you do not succeed to see any independent window (only HTML-based screens inside your WEB-browser main window) it may mean that your WEB-browser does not support Java. For example, Internet Explorer/Netscape could be installed without Java option. In that case you should reinstall your WEB-browser and make sure that Java option is enabled. 12.
80 by default) enter: "http://a.b.c.d/”; b2. If you reconfigured the HTTP port value (e.g. port=2000) enter: "http://a.b.c.d:2000/" c) Use "Tools"/"WEB browser"/"Management Page" in order to get GUI access to all supported devices. You may leave the browser window open and switch to it whenever you need it. Please note that polling is done automatically and you will always see the most recent status in this window. d) Optional. You may perform step b. for any supported device located on the HP OV map.
Logging In When you start MegaVision, you can log in as user or supervisor. As a user, you can view network configuration and device status, but you cannot make any changes in the network. As a supervisor, you can view network configuration and device status, and change configurations and parameters of network devices.
MegaVision allows the network manager to switch between SUPERVISOR and USER modes while the program is running. To change modes, select Login from the Options menu, change modes, then choose OK. If you choose Cancel, the Login window closes and no changes are made. You can bypass the startup Login window and start MegaVision without operator intervention, in either USER or SUPERVISOR mode by setting up the Password window as described in the “Using Passwords” section in this chapter.
Using Passwords In its default configuration, MegaVision requires a password to login. You can also set up the Password window to start the program without a password.. To Change Password Settings As A User Or Supervisor 1. From the Options menu, choose Password. The Password dialog box opens. Figure 2. Password Window 2. Enter your correct Old password. Note: If you are logging in as a supervisor for the first time, press Tab in the Old Password field.
Main Window The MegaVision main window is the major gateway to all monitoring and control functions of devices on your network. The main window contains the map/submap - the graphical representation of your network. Each device that has been correctly added to the map appears as an icon with its device name. Double-clicking an icon opens the Device main window, which presents a graphical depiction of the device’s front panel. (See “About the Device Main Window” below.
5. 6. 7. 8. 9. 10. 11. 12. 13. Copy the selected device to buffer (for later paste) Cut: copy and remove the selected device from the map. Paste previously cut/copied device. Open the Describe window for the selected device. Open the SNMP Device Identify window for the selected device. Open the ARP Table for the selected device. Open the Alias Manager window for the selected device. Open the Alarms Log window. Open MegaVision’s help file.
Adding Background Images You may add a background image to the main map by selecting Select Background Image from the Map menu item. Some bitmaps are included with MegaVision, or you may specify your own bitmap (only the .bmp format is supported). Use Images editing programs (like MS Windows “Paint”) to create/edit bitmaps. Figure 4. Set Background Image • • • • If you have a background, but no longer want it, select the Set No Image radio button.
Device Main Window Each device on the MegaVision map has a main window that displays the front panel of that device. From this panel you can quickly monitor the device’s operations in real time. LEDs on the port image buttons indicate activity, collisions, and flow control for each port on the device. In addition to monitoring information, the Device main window provides you with access to sets of Control Windows that contain additional configuration and performance information.
Control Windows The Device Main Window provides access to a set of Control Windows, through which the Network Manager can perform remote control operations on the managed devices, change the device parameters. Although control windows come in a variety of layouts and perform different functions, most have a common set of features as can be seen in the following Port Configuration window. Figure 6. Control Window MPORTANT NOTE: Control Windows generally have OK, CANCEL and HELP buttons. 1.
Graphics Support You can graphically view counters data as speedometer, line, or bar graphs. These alternate views of data make it easier to analyze and compare statistics at a glance. A tiling option allows you to neatly line up several graphic windows on the screen. Statistics in any window that contains the Graphics image can be viewed as a graph. The Ports button will open a graph window, which allows seeing graphs for all the counters per selected port.
Speedometers This type of display shows the instantaneous value of a selected counter in a speedometerlike window. The window contains a moving indicator, the counter category, and the current value. This view is most helpful during situations such as excessive collisions, where you need to adjust system parameters to improve traffic flow. Click on the Spdm check box next to a desired counter to open a Speedometer graph for this counter. Figure 9. Speedometer.
Line Graphs The line graph feature provides a wide variety of options for monitoring and comparing data. In its simplest form, one graph for each counter is displayed in separate windows showing current activity. When you open a line graph window, the selected counter’s activity is dynamically recorded in one polling interval increments on the graph. Line graphs are especially useful for highlighting trends. Click the Line check box for the counter you wish to view. A line graph for the counter displays.
in a new window. Figure 11b. Multiple Line Graphs. For some statistic-to-graph conversions, you will need to use the multiply coefficients to properly scale graph lines, especially when you use two counter categories, where values might have large differences. By entering a multiply coefficient for a counter, its current graph value is multiplied by the coefficient.
Figure 12. Graph Options Dialog. 1. Polling Interval Changes the value for the Lines graph main window and its parent (see figure 8.) 2. Min Y, Max Y, Min t, Max t Changes the scaling ranges for the Y-axis and X (t) axis. If you check Automatic Change of Ranges, changes are made automatically. NOTE: For graphs, where the X-axis indicates time, the X check box should be always checked. Sometimes it is better to turn off the Y check box, especially when graphs have peaks. 3.
In addition to Line and Speedometer Graphs, MegaVision also supports bar graphs. You can display data from any counter with bars. You can add data from a counter to an existing bar graph (default), or generate a new graph Use bar graphs for comparing the relative amounts of two or more values. The basic rules for configuring bar graphs are the same as for line graphs. Figure 14. Bar Graph. The buttons at the bottom of the window have the same function as those in the line graphs window.
Alarms Alarms are activated by status changes in network devices. When MegaVision detects a change in a device, it generates an alarm. A beep is sounded and the alarm is recorded in the Alarm Log, indicating the date and time, the device in which it occurred, the severity, and a short description of the reason for the alarm. An alarm is also reflected in the device icon— the icon color changes according to the severity of the alarm.
Alarms Configuration Window You can change the severity level of any situation that calls for an alarm. You can choose to record or not record an alarm in the Alarm Log. You can also choose to receive e-mail notifications about some alarms. To open the Alarms Configuration window for the selected device click on the Alarms Configuration from the main window menu Options item. This window can be also accessed from the device specific functions menu by right mouse click. Figure 16.
Figure 17. E-mail Configuration window. After setting the necessary E-mail Configuration parameters you may send the control Email in order to make sure that e-mal notification works. Click on the Send E-mail button to open Send E-mail window. Figure 18. Send E-mail window. Clicking the OK button will send the message.
Figure 19. Remote MegaVision-WEB GUI interface.
SNMP Management Information Base (MIB) Browser MegaVision provides an SNMP MIB browser. From the Main Window menu Control item, select MIBView. You can carry out any SNMP operation on the value of an object from any MIB listed in the MIB files list. Select a device from the Devices list and a MIB from the MIB files list. The MIB Objects list box displays a list of the MIB entries of the current MIB, together with Free Objects entries, which contain non-indexed variables.
Add, Remove, Change, and Compile buttons are used to add new MIBs to the MibView window. It is recommended to place the MIB file in the application’s MIBS directory. Important: There is no guarantee that new MIBs will be compiled properly. That is why those users, who want to use this feature, must have ability to analyze the output errors and understand ASN1 language.
Interfaces Monitoring MegaVision provides extensive monitoring performance of any SNMP devices interfaces, whether they belong to the supported set of devices or not. Interfaces monitoring may be accessed through the Monitor menu item on the main menu bar. The various options will be described below. Interfaces Table Window Enter this window via Monitor/Interfaces Table in the main menu bar or by clicking the Interfaces Table button in the Identify Window.
• Operational Status of the Interface (up/down/testing) – the current operational state of the interface. The testing state indicates that no operational packets can be passed. Double click on the desired interface line or click on the Statistics and Graphs per Interface button to open Interfaces Statistics (per interface) window (described immediately after this section, figure 22.) This action will display performance information about this particular interface.
The information is based on the ifTab (RFC1213, MIB-II). The counters are described there as follows: • Input Bytes - the total number of octets received on the interface, including framing characters. • Input Unicast Packets - the number of subnetwork-unicast packets delivered to a higher-layer protocol. • Input Non-Unicast Packets - the number of non-unicast (i.e., subnetworkbroadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.
Figure 23. Statistics and Graphs per Counter window Interfaces Utilization Window. You may enter this window from: 1. The Main Menu Bar (under Monitor) 2. The Utilization button in the Interfaces Table window 3. From the device window menu bar of certain devices.
Figure 24. Interfaces Utilization window The buttons at the bottom of the graphs have the same function as those in the line graphs window. This window shows the interface’s utilization in percent (right bar graphs) and the interface’s errors per second (left trend graph). The information is based on device Interface Table (ifTable from MIB-II, RFC1213). You can use the standard Graphics Support for this window (described in the “Graphics Support” section).
RMON Support MegaVision supports RMON Groups 1,2,3,9 for any RMON-capable device, which supports the same groups via SNMP. RMON Group 1 Statistics Window You can enter this window from: 1. The Main Window Menu Bar (under Monitor: RMON Group 1 Statistics) 2. From the device window menu bar of certain devices. Figure 29. RMON Group 1 Window. • • • • • The selected device is displayed in the Device Name field, but you can select any device on the map via the pull-down menu.
• This window shows the Control Table in the upper left corner. The table presents control entries for RMON Group 1. Each entry corresponds to one of the device’s interfaces. Usually this table contains entries for all of the interfaces on the monitored device. If this table is empty it may be due to one of the following: RMON Group 1 is not supported for this device or RMON Group 1 is supported but there are no control entries: You can create an entry for any interface by clicking on the Create button.
RMON Group 2 (History) Window You can enter this window from 1. The Main Window Menu Bar (Monitor: RMON Group 2) 2. From the device window menu bar for certain devices. Figure 30. RMON Group 2 Window. Information presented in the window includes: The History Control Table. This table presents control entries for RMON Group 2 (History). Each interface may have several corresponding entries in this table (the default is two entries per interface, with long and short reporting intervals).
Figure 31. Add RMON Group 2 Control Entry Window. You are required to enter some information, which describes how to collect statistics for reporting: 1. The desired Interface Number. 2. The Owner String to identify the entry owner (not required); 3. Number of Buckets: the requested number of discrete time intervals over which data will be collected. It is actually the number of samples. Values greater than 50 are not recommended.
When you open RMON Group 2 Window or select any History Control Table Entry, two Trend Graph Windows open (in addition to the main window) to reflect the History Table Information graphically: • • Interface Errors per interval (right window). Interface Utilization per interval in % (left window). While in the RMON Group 2 Window, you may jump to any other device without selecting it in the main map via the Device Name box (in the bottom right corner of Figure 30).
interfaces, but may be empty as well (this is the default ). If this table is empty, it is due to one of the following reasons: • RMON Group 3 is not supported on this device. • RMON Group 3 is supported but there are no control threshold entries. You can create a threshold entry for any interface by clicking on the Create button. The Add RMON Group 3 window opens. Figure 33.
• Rising Event Index: The Index from the Events Table (see below) which corresponds to Rising Event. • Falling Event Index: The Index from the Events Table (see below), which corresponds to Falling Event. • Start Up: The start-up alarm, i.e., conditions for an alarm to be sent as a result of the first sample. You may select from: Rising, Falling, or RisingOrFalling. • Owner String: String to Identify the entry owner (usually not required).
• Event Description • Community: A value for the trap being sent when the event is triggered. Note that all the traps are reflected in the Alarms Log. You may view the Alarms Log by selecting the Monitor: Alarm Log main menu item. • Owner String: A string to identify the entry owner (usually not required). Press OK in the Add Event (RMON Group 9) window. If the Create operation fails, it may mean that RMON Group 9 is not supported on this device.
Adding and Deleting Devices. Describe Window. Before you can manage a device, you must first define the device, provide parameters to establish communication, and select an interface. Only the SUPERVISOR may add devices and modify their attributes. Please note that you may add devices either manually or using Autodiscovery function (see the Autodiscovery section later). Adding Devices Manually. MegaVision requires specific parameters to establish communication with a device.
Figure 36. Describe Window. 4. In the Name field, type a map name for the device. 5. In the SNMP Community Names section, type a Community Name for GET and a Community Name for SET. (The default values are “public” for Get operations and “private” for Set operations.) 6. Use the Notepad field to note additional comments about the device. 7. The Interfaces list defines all IP interfaces available to the device for communication with the network.
9. In the IP Address field, enter the IP Address for the interface. Select an interface from the Interface Type list. Choose Ethernet when this interface is connected to the Ethernet LAN. Choose SLIP when the interface is connected to the serial line. Enter values for Polling Interval, Time-Out, and Number of Retries. CAUTION: Set the Polling Interval time with care.
Figure 38. A map with a submap. There are two ways to create a submap. 1. The first way will create a submap and place the submap icon on the map. Select Add from the Main Window menu Edit item. The Devices Types window opens. Choose SUMBAP in order to add a new map/submap to the current map. The Describe Submap Window opens. Enter a submap name in the Name field and click the OK button. Figure 39. Describe Submap Window. 2. The second way will create a submap without placing the submap icon on the map.
The newly created map opens immediately after you click OK in the New Map window. Note that you may also use the Open Map window to delete maps or open any of the previously created maps. Figure 40. Open Map Window. Cutting, Pasting, Dragging, and Dropping There are several operations, which can make working with submaps easier: cut, paste, and drag & drop. You can also move devices icons on the map with your mouse by “dragging” them into the desired location.
Autodiscovery The autodiscovery process allows you to easily add network devices without knowing their IP addresses. MegaVision polls each IP address within the given range and adds devices automatically. To start the autodiscovery process, select Autodiscovery from the Main Window menu Map item. Autodiscovery window opens. Figure 43. Autodiscovery Window Click on the Start Discovery button after entering the desired options. • Discovery Type: You may choose to discover: 1) Only supported SNMP devices.
Links To help you visualize your network configuration, you may add links between devices on the map. Links are added manually. To add a link, select Add Link from the Main Window menu Edit item (pictured below). The current link is highlighted (p3p4 in the figure). To rename an existing link, double-click on it. Both of these actions open the Describe Link window. In this window, you can name the link and select its color and width.
General Device Information: SNMP Device Identify Window The SNMP Device Identify window provides you with a quick look at basic information about a device — items such as product type, up time, device location, and contact. The information is retrieved via SNMP according to MIB-2 (RFC-1213) specification. You can open the window via Main Window menu Monitor/Identify item. Figure 43.
Generic SNMP and TCP/IP Devices, Monitoring services Generic SNMP Device. The Generic SNMP Device type allows you to manage any SNMP compliant device. The Generic SNMP Device window opens when you double click on a Generic device icon. This window is similar to the SNMP Device Identify window. Generic SNMP devices may send standard SNMP traps (alarms) and MegaVision is able to receive them. There are two types of Generic SNMP Devices: GENERIC and ROUTER.
Figure 45. TCPIP device icon and TCPIP device main window Monitoring Services. MegaVision allows to monitor performance of business-critical Layer 7 network services, such as e-mail, HTTP, FTP, DNS, etc. The services are learned automatically for any device, which is located on the map. The Services Monitor window may be accessed via Main Window menu Monitor/Services Monitor item, or via device specific menu, which pops up by right mouse click on the selected device. Figure 46.
directory contains information how to see/modify the full list of monitored services. You can use the standard MegaVision Graphics Support (see the Graphics Support section) in order to view the corresponding services performance graphs. You can configure MegaVision to collect the history performance data into a file for later analysis. Click on the Configure Collecting… button to enter the Services Configuration window. Figure 47.
Alias Manager MegaVision allows you to assign aliases to MAC addresses, easing identification of network devices and stations. Each network device (a workstation, switch, hub, printer, etc) has it’s own unique 12 hexadecimal digit MAC-Address. This MAC-Address is associated with the network interface, used to connect the device. The first 6 digits denote the device vendor. The user may assign an alias to any complete MAC address or the 6-digit vendor code.
If there is only a vendor part of MAC address, MegaVision will append the remaining digits. If there is no corresponding alias entry just the MAC address will be displayed. Please, note that there are some other windows (besides Alias Manager), which allow assigning aliases to MAC Addresses, e.g. Add/Edit ARP Entry window, which is accessible via ARP Table window.
TereScope™ Management In order to optimally integrate the TereScope™ Wireless Optical links into complete network solutions, the TereScope™ products are SNMP manageable. Each of the two transceiver units of the wireless optical link is equipped with a separate management 10 Base T interface. Through this interface TereScope™ systems can be managed through Optical Access MegaVision™ SNMP Web Based management software as indicated in the picture.

Running MegaVision as a plug-in application for different NMS platforms There some differences between the way MegaVision-WEB and MegaVision Classic work under standard NMS Platforms. MegaVision-WEB uses its Java-based WEB interface to access its GUI from different platforms. Please, note that in order to achieve such integration there should be a PC running MegaVision-WEB server plugged somewhere in the network, which runs 24x7 collecting management data.
MegaVision Classic under HP OpenView Windows The following directions describe how to install a MegaVision for HP OpenView for MSWindows. Following that are instructions for adding a device, which is necessary before you can access the device with MegaVision. Before you install MegaVision software, you must have MS-Windows and HP OpenView for MS-Windows, version 7.1 or higher (including HP OV Professional Suite) installed on the management station.
MegaVision Classic under Castle Rock SNMPc Network Manager SNMPc version must be 4.x or SNMPc for Win-NT (5.x). Please note that MegaVision has two different options for SNMPc 4.x and SNMPc NT (5.x). There is some Network Management products, that are based on SNMPc, e.g.: a) Fibronics InterView/Win. b) Intel LANDesk Network Manager. c) Cisco CiscoWorks. If you have SNMPc or one of the products you may use MegaVision for SNMPc to manage all the supported different vendors devices from one platform.
MegaVision Classic under Spectrum 4.0 for Windows NT MegaVision Classic can function as an application for Cabletron Spectrum 4.0 rev. 1 and higher, running on Windows NT 3.51.
1. Check that the current image represents an SNMP device. The “MegaVision” item should not appear within non-SNMP devices. 2. In the DOS prompt or SpectroSHELL prompt, change your working directory to \SG-Support\CsIib\GnSNMPDev directory, ( is a Spectrum directory) There are three ASCII files if interest there: Large.Bas, Small.Bas, The.OPR You may view/edit them using any DOS editor or the “vi” editor under SpectroSHELL. These files should contain the following string: Script.
