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. For multiple details about different devices management please refer to
MegaVision online HELP .
There are two basic versions of MegaVision: MegaVision-WEB and MegaVision Classic.
Mega Vision -WEB
MegaVision-WEB runs on Win95/Win98/WinNT/Win2000. However, its rich GUI (graphical
user interface) can be accessed on ANY platform (see below).
There are two different ways, which MegaVision-WEB GUI can be accessed:
1. Local GUI is provided on the same PC, which is running MegaVision-WEB.
2. Remote WEB-Console GUI can be accessed from any computer (any OS, including
UNIX, Linux...), which is capable of running J ava-enabled WEB-browser (like
Netscape or Internet Explorer). There is NO specific console software required. J ust
start your WEB-browser and point it to the address: "http://<IP Address>/", where
<IP Address> is IP Address of the PC MegaVision-WEB is running on. This feature
allows to monitor/configure your network from any point in the world, which has
Internet/Intranet connection. It also allows managing supported devices from
standard NMS platforms (such as HP OV NNM UNIX, please see below)
Mega Vision Cla ssic
MegaVision Classic is an older version of MegaVision. It is kept mostly for backward
compatibility and capability of native integration with some NMS platforms.
MegaVision Classic runs on Win3.1/ Win95/Win98/WinNT/Win2000
MegaVision Classic can be installed as:
1. Standalone MS-Windows application. In this configuration it provides its own
mapping, alarm color-handling and polling capabilities. MegaVision Classic
Sta n d a lon e ver sion is k ep t for b a ck w a r d com p a tib ility on ly. It is str on gly
r ecom m en d ed u sin g Mega Vision -WEB a s a sta n d a lon e a p p lica tion .
MegaVision-WEB local GUI has all the capabilities of MegaVision Classic Standalone
and much more.
2. Plug-in application for HP OpenView Windows (version 7.1 and higher, including HP
OV Professional Suite).
3. Plug-in application for Castle Rock SNMPc 4.x or SNMPc NT 5.x.
4. Plug-in application for Cabletron SPECTRUM 4.0 rev1 and higher (WinNT 3.51).
5. Plug-in application for HP OV NNM (WinNT, Win2000).
When working as plug-in application MegaVision uses mapping and alarm color handling
features provided by the corresponding NMS platform.

Mega Vision Fea tu r es
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.
End-to-end network monitoring and configuration. Hierarchical maps allow graphical
presentation and inventory of the whole network.
•
•
•
•
•
•
•
•
•
•
In-band and/or out-of-band access via SLIP RS-232.
Multiple devices are monitored and controlled at the same time.
TFTP/BootP client/server.
RMON groups 1,2,3,9 GUI supported for any RMON capable device.
Automatic inactivity discovery of SNMP and TCP/IP devices.
Configurable immediate visual and sound notification of SNMP alarms/traps.
Virtual LANs graphical setup and display.
User defined alarms thresholds.
Adjustable polling intervals to limit network management overhead
Access security through use of passwords. Two levels of passwords allow monitoring
and display only (user) or monitoring, display and configuration of the devices
(supervisor).
MegaVision-WEB additionally contains the following features:
•
WEB-GUI interface. All the MegaVision screens may be accessed remotely via WEB
from ANY platform including UNIX/LINUX and HP OV NNM UNIX. (The local GUI
interface is still there).
•
•
Configurable E-mail Notification (through e-mail it can go to pagers, etc.);
Devices are being polled and receive traps, even if they belong to CLOSED MAP.
This feature basically takes out the limitation of the network size.
Services Monitor: possibility to monitor performance of mission-critical Layer-7
network services, such as e-mail, FTP, e-commerce (http) etc. Collecting history in log
files is available. Helps carriers (service providers) to track the SLAs (Service Level
Agreements) and can be used to discover the need for QoS (Quality of Services)
configuration.
•
MegaVision is designed with the network manager in mind. By using built-in tools for
monitoring up-to-the minute information and statistics, and reconfiguring the system as
network requirements grow and evolve, you can maintain a network that operates at peak
performance—maximum throughput, network stability, and minimal downtime.

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. The "Login" Screen will
appear. Choose SUPERVISOR and press OK with NO password.
4. Because it is your first time start, the "License Password" request screen will appear.
You need to enter your license password in order to continue. This password is
connected to the IP Address of the PC running MegaVision-WEB. You can obtain
your password via e-mail from "megavision@nbase-xyplex.com". Your e-mail request
for password must include the IP Address and MegaVision Serial Number (found on
the package).
5. Use MegaVision Main Menu "Map"/"Autodiscovery" or "Edit"/"Add" functions to add
devices icons to the MegaVision map. The device icons colors mean:
a. Green (OK): the device communication status is OK.
b. Red (Critical): there is no communication with the device.
c. Gray (Unknown): the device communication status is unknown.
d. Yellow (Warning): there are some warnings about this device in the alarms log.
e. Purple (Info): there are some info messages about this device in the alarms log.
Double-click on the device icon. The Device Main window appears. It usually
represents the device front panel with real-time status LEDs. Ports that are grayed-
out are inactive. Click on the Company/device logo symbol to enter the System
management subtree. Click on a port to enter the Port Management subtree. The
Main window menu or the Device Main window menu provides shortcuts to other
windows. If you need more information, use the ON-LINE HELP or the window-
specific HELP.
6. Use "Edit"/"Add Link”,” Map"/"Set Background Image”, "Edit"/"Add
Device"(SUBMAP) to create links, submaps and get the realistic view of your
network.
7. Use "Internet Options"/"E-mail configuration" and "Options"/"Alarms Configuration"
to configure alarms and e-mail notifications. Use "Monitor/Services Monitor" to
monitor mission-critical network services, such as e-mail, FTP, e-commerce, etc.
8. In order to get access via WEB you must leave your MegaVision-WEB running all the
time. You may reconfigure the HTTP port value via "Internet options"/"Set HTTP
Port" (by default this port is 80 but you may need to configure another value if you
have another WEB-server application (like Microsoft Internet Information Server)
running on the same PC.)
9. You may use the WEB-Console from any computer, which is connected to the
Internet/Intranet. Start the WEB-browser and point it to the following URL:
a. If you did not reconfigure the HTTP port value (it is 80 by default) enter:
"http://a.b.c.d/"
b. If you reconfigured the HTTP port value (e.g. port=2000) enter:
"http://a.b.c.d:2000/"
(where a.b.c.d is the IP Address of the PC running MegaVision WEB, e.g.:
192.168.1.97)
Your WEB-browser will show the "Remote Console" Login/Password Screen.
Download from Www.Somanuals.com. All Manuals Search And Download.
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. However, Microsoft Internet Explorer may give
you the following error: "Error: Security Exception while creating Server socket" If
you receive such error, please do the following configuration steps:
a. From the Internet Explorer main menu enter to the "Tools"/"Internet
Options"/"Security" screen.
b. Click on the "Trusted Sites" image.
c. Click on "Sites..." button. The "Trusted Sites" Screen will appear. Add the
following address to your trusted sites: "http://a.b.c.d" (where a.b.c.d is the IP
address of the computer running MegaVision-WEB. Do not forget to uncheck
the check box: "Require server verification (https:) for all sites in this zone"
(Otherwise, Internet Explorer will not allow to add the above address to the
trusted sites lists). Click "OK" to close the "Trusted Sites" screen.
d. Click on the "Custom Level..." button in the "Internet Options"/"Security"
screen. The "Security Settings" screen will appear. Scroll in the screen to find
"Microsoft VM/J ava Permissions/Custom" check box and check it. Click on
the "J ava Custom Setting..." button in the same screen. The "Trusted Sites"
Permissions screen will appear. Click on "Edit Permissions" bar and scroll in
the screen to ENABLE (check) ALL THE OPTIONS you see there. Please,
note that you do not compromise the security, because all the changes are
done ONLY for the trusted sites zone Confirm your changes by pressing the
"Apply"/"OK" button in all the screens.

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 J ava. For example,
Internet Explorer/Netscape could be installed without J ava option. In that case you
should reinstall your WEB-browser and make sure that J ava option is enabled.
12. Tip: while working with remote console via WEB browser there maybe physical
network problems or too slow Internet connection which can lead to the session
canceling because of timeouts. User is required to enter his password again to be
connected to the server and continue the work (security reasons). All the previous
session windows may stay on the screen, though they are not usable any more. In
that case it is recommended to close WEB browser and enter it again BEFORE
entering a new session. This will automatically close all the previous session
windows. (If you prefer not to close the browser, you can still close the old session
windows "one by one" using double-click on the windows upper left corner, however,
please note that the window will be closed only after three consecutive double-clicks)
13. Some known problems.
a. It is strongly recommended NOT TO INSTALL MegaVision-WEB on the
DRIVES, which belong to remote network computers. The issue is connected
to selecting MegaVision-WEB root directory. This may crash MegaVision
WEB server.
b. It is strongly recommended NOT TO USE long directory names like
"Program Files” as a root MegaVision directory. The issue is connected to
selecting MegaVision-WEB root directory. This may crash MegaVision WEB
server.
c. It is strongly recommended NOT TO USE SLOW computers as a WEB-
remote console (see MegaVision WEB platform requirements below). This
may lead to slow GUI and regular sessions canceling because of timeouts.

Wor kin g u n d er HP OV NNM UNIX
MegaVision-WEB GUI can be accessed from any standard NMS platform. Please, review the
following notes for HP OV NNM UNIX as an example how to organize such interface.
HP OV NNM Versions 5.x and higher allow to call WEB browser for any device icon, which is
located on the HP OV NNM Map. This feature may be used to provide seamless GUI access
to all managed devices.
Here are the steps you should perform.
a) Use HP OV NNM "Edit"/"Find"/"Object by Attribute"/"IP Address" to find the PC
which is running MegaVision-WEB (IP address" "a.b.c.d"). (Note: If you cannot find
such icon, you must create it manually via "Edit"/"Add Object").
b) Use "Right Mouse Button click"/"Object Properties" to open HP OV NNM "Object
Properties" Window. Select "General Attributes" and make sure that
"isHTTPsupported" and "isHTTPmanaged" properties are enabled. Enter the
"ManagementURL" like this: b1. If you did not reconfigure the HTTP port value (it is
Download from Www.Somanuals.com. All Manuals Search And Download.
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. In this case you can receive MegaVision-WEB GUI without looking for the
MegaVision-WEB PC Icon first.

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.) Choosing an icon makes that device the “current device”.
Additional commands are available through cascading menus of the menu bar, or by using
the shortcut icons under the menu items. Note, that you may move devices icons on the map
with your mouse by “dragging” them into the desired location.
Figure 3. Main Window
Shortcut Icons
Thirteen shortcut icons appear under the menu bar. From left to right, their functions are:
1. Add a device.
2. Delete the current device.
3. Add a link.

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 Con tr ol Win d ow s that contain additional configuration and performance
information. These sub-windows also allow you to control and change parameters of the
device.
In this manual the front panel of the Optical Access OptiSwitch 800R is used as an example.
If you have other supported devices installed on your network, the front panel display will
vary.

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 p er selected p or t. The Cnts
button will open a graph window, which allows seeing graphs for all the ports p er selected
cou n ter .
Figure 7. Graphics Image.
Figure 8 is an example of a window with graph support. Whenever you encounter a window
with graphic support elements, counter data can be viewed as a speedometer, line or bars
graph.

Speedometers
This type of display shows the instantaneous value of a selected counter in a speedometer-
like 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 Sp d m check box next
to a desired counter to open a Speedometer graph for this counter.
Figure 9. Speedometer.
The Op tn button opens the Speedometer Options dialog box. These options allow you to
reconfigure the speedometer. The band between the Critical value and the Max value
changes to red on 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 Lin e check box for the counter you wish to
view. A line graph for the counter displays. Figure 11a illustrates the Input Bytes activity for
port 2.
Figure 11a. Line Graph.
For more sophisticated analysis and comparison, multiple line graphs — up to 16 linear
graphs— can be included in a single window. You can view statistics in many configurations:
•
•
•
same counter for different ports (figure 7, Cn ts button);
different counters for a single port (figure 7, P or ts button);
different counters for different ports (figure 8, Change the port value);
To view another counter in the same window click the Lin e check box for that counter.
To view another counter in another window, choose New w in d ow s in the Ad d Gr a p h s As
section, then click the Lin e check box for that counter. 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 m u ltip ly 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. This allows you to view several counters that
have different dimensions in one graph window, for example, Received Bytes and
Transmitted Packets.
Buttons located below the graph (Figure 11a) allow you to obtain further information and
provide options for additional window configuration.
Stop - Halts recording of statistics on a graph. To resume drawing, click on the button again.
Help - Provides a brief description of graphics support features.
Options - Opens the Graph Options dialog box. Please, note that these options allow you to
reconfigure the Lines graph window parameters and polling interval for the parent window
(see figure 8.)

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.

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 have four severity
levels, each represented by a different color: Critical, Warning, Normal, and Informational.
Please note that a lot of alarms are actually generated by SNMP Traps, which are sent by
different network devices.
Alarm Notifications
In addition to an audible sound notifying you of an alarm condition, the color of a device icon
corresponds to the latest alarm with the highest severity. When an event received cancels
any previously received alarm, and the color of the icon is updated to reflect the new status of
the device.

SNMP Management Information Base (MIB) Browser
MegaVision provides an SNMP MIB browser. From the Main Window menu Con tr ol 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. The name and
value of the selected MIB Object are displayed in editable text and value boxes. You traverse
through the MIB tree by clicking on the desired entries.
Figure 20. MIBView Window
MIBView enables the user to Get the value of any object from any one of the MIBs that are
listed in the mibs.all file (located in the application’s root directory). The MIB variable is
displayed either as a text in the edit box, or as a value in a combo-box (if it is enumerated in
the MIB). Users can also use the Next button to perform SNMP Get-Next operation or the
Set button to change the value of an object. The name of the current device is displayed and
can be set via the upper combo-box. Users can select MIB from the “MIB files” list box.
There are some other buttons, which help the MIB browsing process. Click on the Mon itor
button to poll selected MIB-variable every 1 sec. Click on the Stop button to stop polling
(monitoring). Click on the GetEn t r y button to get the whole SNMP TABLE ENTRY (the
entry index must be entered first).

Ad d , R em ove, Ch a n ge, and Com p ile 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.
Im p or ta n t:
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. Please, note also, that usually there is no need to add new MIBs, because a
lot of standard and private MIBs are already included by default.

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 Mon itor /In ter fa ces Ta b le in the main menu bar or by clicking the
In ter fa ces Ta ble button in the Identify Window. The Interfaces Table window displays
information about a device’s interfaces. It based on the information from the ifTab (RFC1213,
MIB-II). Any SNMP-compliant device must support Interfaces Table.
Figure 21. Interfaces Table.
Below is a list of information presented in the Interfaces Table, regardless of the interface
type:
•
•
•
In ter fa ce Nu m b er – number of interface (corresponds to ifIndex from MIB-2)
In ter fa ce Descr ip tion - a textual string containing information about the interface.
In ter fa ce Typ e - the type of interface, distinguished according to the physical/link
protocol(s) immediately ‘'below' the network layer in the protocol stack.
In ter fa ce Sp eed - an interface's current bandwidth in bits per second. For
interfaces, which do not vary in bandwidth, or for those where no accurate estimation
can be made, this object should contain the nominal bandwidth.
•
•
MAC Ad d r ess - the interface's address at the protocol layer immediately ‘below’ the
network layer in the protocol stack. For interfaces, which do not have such an
address (e.g., a serial line), this object should contain an octet string of zero length. If
the address does not have an alias, then the raw address will be displayed.
Otherwise, the current alias name will be displayed. The user may add/edit aliases
via the ARP Add/Edit window, Alias Manager Window, or other windows, which
allow aliases editing.

•
Op er a tion a l Sta tu s of th e In ter fa ce (u p /d ow n /testin g) – 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 St a tistics a n d Gr a p h s p er
In ter fa ce button to open In ter fa ces Sta tistics (p er in ter fa ce) window (described
immediately after this section, figure 22.) This action will display performance information
about this particular interface.
Press on the Sta tistics a n d Gr a p h s p er Cou n ter button to open In ter fa ces Sta tistics
(p er cou n ter ), window (described after Interface Statistics window, figure 23.). This action
will display performance information about all the interfaces on this particular device
The Utiliza tion button brings up a graph window representing the interfaces utilization.
This window is described later in this section (figure 24.)
Interfaces Statistics (per Interface) Window
This window shows the interface statistics counters for the selected interface. Enter this
window via the Statistics and Graphs per Interface button in the Interfaces Table Window.
By default the interfaces numbers next to all the counters correspond to the selected
interface, but you may change them. The counters are updated in real time, based on the
polling interval. You can use the standard Graphics Support for the windows counters .You
can select various counters per interface to display graphically via the check boxes. If you
want to graph data from another interface, use the Intf# fields to select the desired interface
number.
Figure 22. Interfaces Statistics (per interface) window

The information is based on the ifTab (RFC1213, MIB-II). The counters are described there
as follows:
•
•
•
•
In p u t Bytes - the total number of octets received on the interface, including framing
characters.
In p u t Un ica st P a ck ets - the number of subnetwork-unicast packets delivered to a
higher-layer protocol.
In p u t Non -Un ica st P a ck ets - the number of non-unicast (i.e., subnetwork-
broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.
In p u t Disca r d ed P a ck ets - the total number of inbound packets which were
chosen to be discarded even though no errors had been detected to prevent their
being deliverable to a higher-layer protocol. One possible reason for discarding such a
packet is to free up buffer space.
•
•
•
•
In p u t E r r or P a ck ets - the number of inbound packets that contained errors
preventing them from being deliverable to a higher-layer protocol.
In p u t Un k n ow n P r otocol P a ck ets - the number of packets received via the
interface, which were discarded because of an unknown or unsupported protocol.
Ou t p u t Bytes - the total number of octets transmitted out of the interface, including
framing characters.
Ou t p u t Un ica st P a ck ets - the total number of packets that higher-level protocols
requested be transmitted to a subnetwork-unicast address, including those that were
discarded or not sent.
•
Ou t p u t Non -Un ica st P a ck ets - the total number of packets that higher-level
protocols requested be transmitted to a non-unicast (i.e., a subnetwork-broadcast or
subnetwork-multicast) address, including those that were discarded or not sent.
Ou tp u t Disca r d ed P a ck ets - the number of outbound packets, which were chosen
to be discarded even though no errors had been detected to prevent their being
transmitted. One possible reason for discarding such a packet could be to free up
buffer space.
•
•
•
Ou t p u t E r r or P a ck ets - the number of outbound packets that could not be
transmitted because of errors.
Ou t p u t Qu eu e Len gth - the length of the output packet queue (in packets).

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
Au tod iscover y function (see the Au tod iscover y section later).
Ad d in g Devices Ma n u a lly.
MegaVision requires specific parameters to establish communication with a device. You must
supply a name and address, specify communication type, enter polling durations, and SNMP
community names.
In order to add device manually:
1. Select Ad d from the Main Window menu Ed it item. The Devices Typ es window
opens:
Figure 35. Devices Types Window
2. Select a desired device type. Choose GENERIC for any unsupported SNMP device.
Choose TCPIP for any device, which does not support SNMP. Choose SUMBAP in
order to add a new map/submap to the current map.
3. A Describe window for the device opens.
Download from Www.Somanuals.com. All Manuals Search And Download.
Figure 36. Describe Window.
4. In the Na m e field, type a map name for the device.
5. In the SNMP Com m u n ity Na m es 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 Notep a d field to note additional comments about the device.
7. The In ter fa ces list defines all IP interfaces available to the device for
communication with the network. The first interface on the list receives the highest
priority for establishing communication. If communication cannot be established
through that interface, the next interface is tried. You enter interface specifications
in the Defin e In ter fa ce Window.
8. To define new interfaces choose Ad d in the Descr ibe window. You may also modify
the existing interface. To do this, select it and press Mod ify button or double-click on
the interface line. The Defin e In ter fa ce Window opens.
Figure 37. Define Interface Window.

9. In the IP Ad d r ess field, enter the IP Address for the interface. Select an interface
from the In ter fa ce Typ e list. Choose Eth er n et when this interface is connected to
the Ethernet LAN. Choose SLIP when the interface is connected to the serial line.
Enter values for P ollin g In ter va l, Tim e-Ou t, and Number of R etr ies.
CAUTION: Set the Polling Interval time with care. Setting it to a high value may
cause a slow response to network errors, while setting it to a low value may flood the
network with large quantities of management traffic. It is recommended that you use
the default value of 10 seconds, however, if you have more than 1000 devices on all
the maps, you should probably increase this value. It also depends on the fact how
powerful your NMS PC is.
10. Choose OK to add/modify the interface. The Descr ibe window displays with the
newly defined interface inserted above the highlighted line.
11. Choose OK in the Descr ibe Window. The icon representing the new device now
appears on the map. If communication has been successfully established, the device
icon will become green. If communication has not been established, the device icon
will become red.
After a device has been successfully defined, it is polled at every poll interval to check the
communication status. The device’s configuration is automatically learned after initial
connection is established.
Mod ifyin g Device Settin gs.
After a device has been added, you can change set-up parameters or add/modify/delete an
interface through the Descr ibe window.

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. The Alias
manager includes the 6-digit vendor codes for most vendors. Once an alias defined it will be
shown in many MegaVision windows instead of raw MAC-address.

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 Alia s Ma n a ger ), which allow assigning aliases
to MAC Addresses, e.g. Ad d /E d it AR P En t r y window, which is accessible via ARP Ta ble

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 J ava-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 uses native MS-Windows GUI, however the list of supported NMS
platforms is limited to:
1) HP OpenView Windows (version 7.1 and higher, including HP OV Professional
Suite).
2) Castle Rock SNMPc 4.x or SNMPc NT 5.x.
3) Cabletron SPECTRUM 4.0 rev1 and higher (WinNT 3.51).
4) HP OV NNM (WinNT, Win2000).
It is recommended using MegaVision Classic for the above PC NMS platforms. If you need to
manage MegaVision supported devices under UNIX based platforms, use MegaVision-WEB.
Mega Vision -WEB u n d er HP OV NNM UNIX
MegaVision-WEB GUI can be accessed from any standard NMS platform. Please, review the
following notes for HP OV NNM UNIX as an example how to organize such interface.
HP OV NNM Versions 5.x and higher allow to call WEB browser for any device icon, which is
located on the HP OV NNM Map. This feature may be used to provide seamless GUI access
to all managed devices.
Here are the steps you should perform.
1. Use HP OV NNM "Edit"/"Find"/"Object by Attribute"/"IP Address" to find the PC
which is running MegaVision-WEB (IP address" "a.b.c.d"). (Note: If you cannot find
such icon, you must create it manually via "Edit"/"Add Object").
2. Use "Right Mouse Button click"/"Object Properties" to open HP OV NNM "Object
Properties" Window. Select "General Attributes" and make sure that
"isHTTPsupported" and "isHTTPmanaged" properties are enabled. Enter the
"ManagementURL" like this: b1. If you did not reconfigure the HTTP port value (it is
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/"
3. 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.
4. Optional. You may perform step b. for any supported device located on the HP OV
map. In this case you can receive MegaVision-WEB GUI without looking for the
MegaVision-WEB PC Icon first.

Mega Vision Cla ssic u n d er HP Op en View Win d ows
The following directions describe how to install a MegaVision for HP OpenView for MS-
Windows. 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.
Under the MS-Windows Program Manager (or File Manager), go to the disk1 folder and run
SETUP.EXE from the MegaVision Classic Installation kit. This is a standard MS-Windows
installation. Select MegaVision for HP OV option.
When the software has completed the installation, select the OpenView group in the
Program Manager window and Run the HP OpenView application. MegaVision starts
automatically.
To define a new device with HP OV
1. Select Add from the HP OV Edit menu. The Add window opens.
2. Select Components in the pull-down menu. Scroll down the icon window until the
required device icon appears. Choose the icon representing the device you wish to add.
(The cursor changes shape.)
3. Drag and drop the device icon to the HP OpenView map window. The device icon is
added to the map and a MegaVision Describe window opens. See “Ad d in g a n d Deletin g
Devices, Descr ibe Win d ow ” section for additional information.
4. Click OK to return to the HP OpenView main window. A submap with the newly defined
device icon displays. The device icon in the submap is colored, according to HP OpenView
color codes to reflect the current device status. From this point on, the windows are as
described for the MegaVision standalone version, with the exception of the submap
window. To open the device main window, double-click on the device icon.
5. For more information on running HP OpenView, refer to the HP OpenView user
manuals.
IMPORTANT! If you are using HP OV Autodiscovery:
After all the devices are discovered and added to the map:
1. Close discovery process.
2. Save the map. ("File->Save" or "File->Save As");
3. Open the same map again: ("File->Open");
Note that otherwise MegaVision will not get information about newly discovered devices.
Double-click on the device will lead to the error message: "Device is not registered"

Mega Vision Cla ssic u n d er Ca stle Rock SNMP c Networ k Ma n a ger
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. SNMPc (or
LANDesk or InterView/Win, CiscoWorks) must be installed before MegaVision. After
MegaVision installation, it will start automatically when SNMPc starts. Open a new map.
Add some devices to the map or do SNMPc Autodiscovery. SNMPc will automatically assign
the correct icons to the MegaVision devices. When adding devices manually make sure that
the "Icon" field equals "AUTOICON”, “Type" field equals "Agent" and "Exec" field equals
"auto.exe". Double-click on the device icon will open MegaVision device main window.
IMPORTANT: If you are using SNMPc support for HP OpenView, do not install MegaVision
for SNMPc. Use MegaVision for HP OV instead. After MegaVision for HP OV installation,
MegaVision will manage all the MegaVision devices. SNMPc will manage all the others.

Mega Vision Cla ssic u n d er Spectr u m 4.0 for Win d ows NT
MegaVision Classic can function as an application for Cabletron Spectrum 4.0 rev. 1 and
higher, running on Windows NT 3.51. This section contains important information about
running MegaVision and managing supported devices on the Spectrum platform:
• Pre-Installation Notes
• Installing MegaVision
• Running MegaVision
• Receiving SNMP traps from MegaVision Devices
• Troubleshooting
Pre-Installation Notes
You must install MegaVision on every Windows NT machine, which is supposed to run
SpectroGRAPH. Any Spectrum user planning to use MegaVision must have Full Control
permissions to the MegaVision directory tree. Please check that you have enough disk
memory. 20MB is required. Verify that Spectrum is correctly installed on your Windows NT
machine:
1. Go to the command prompt
2. From the prompt type: echo %SPECROOT%
The Spectrum directory path appears. Usually it is “C:\WIN32APP\Spectrum”, but there
are possible other values like “c:\progra~1\spectr~1”.
Installing MegaVision Classic
1. Reboot your Windows NT machine.
2. Login as Local Administrator.
3. Place the MegaVision install CD in the CD drive.
4.Under the Windows NT Program Manager (or File Manager), go to the MegaVision Classic
disk1 folder and run SETUP.EXE. Follow the instructions on the screen.
The installation process puts a “MegaVision Close” icon into the Spectrum Program Group.
Normally this icon is not used. Use it ONLY if you want to close MegaVision (e.g. to free the
memory).
Running MegaVision Classic
1. Start SpectroGRAPH.
2. You may use Spectrum Autodiscovery or manually add new supported devices to Spectrum
views.
Important: When adding manually, please use GnSNMPDev Model Type. Supported
switches are represented by “SNMP BRIDGE” images, supported hubs are represented by
“SNMP HUB” images. Navigate to the desired view and click on the image which represents
any supported device to make the image current.
3. Click on the right mouse button to open the Spectrum Icon Submenu. Find the MegaVision
item and select it there. The first time you do this, the “MegaVision Started!” Window-
Message appears. After clicking on OK, the MegaVision Device Window with real-time status
LEDs appears.
MegaVision automatically recognizes the device type. If the SNMP device is not recognized,
the MegaVision Generic SNMP Device Window opens. If you navigate to any
other device and select the MegaVision item, the MegaVision Device window opens
immediately. This is because MegaVision is already running.
Troubleshooting
Read this section only if you experience problems with MegaVision running under Spectrum.
If You Cannot Find The “MegaVision” Item In The Icon Submenu After MegaVision
Installation:
Download from Www.Somanuals.com. All Manuals Search And Download.
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
<SpecDir>\SG-Support\CsIib\GnSNMPDev directory, (<SpecDir> 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.Act(0,0,Script(“MegaVision”,0x117a7,0x1006e,0x10024,0x1027f,0x100
71,
0x110c4)) The string should appear in the end of every file before “} ” string.
3. Compare the files to the same files in the MegaVision directory..
If You Have Problems Starting MegaVision From The Spectrum
Icon Submenu:
1. In the SpectroSHELL prompt change your working directory to:
<SpecDir>/SG-Support/CsScript (<SpecDir> is a Spectrum directory)
These two files must be present: MegaVision and sendspec.exe
2. If these files do not exist, follow these commands to create them in that directory:
cp <MegaVision Dir>/exe/sendspec.exe <SpecDir>/SG-Support/CsScript
cp <MegaVision Dir>/megavisi.scr <SpecDir>/SG-Support/MegaVision
If you have problems viewing devices front panel (e.g. the sizes of the modules are not correct
and you cannot see all the modules) or some data screens seem misaligned, please change
these Windows Settings:
Change “Control Panel”/”Display”/”Settings”/”Font size” to “Small Fonts”.
