Over vi ew MegaVisio n is a ne twork man age ment applica tion. Its main fu nction is managing a spec ific set of support ed devices, however, i t can dis cover and perform many functions with virtual ly any vendor SNM P or TCP/IP devi ces.
MegaVision Features MegaVision hel ps you to quickly confi gure the network. It detects net work problems, provid es device and port co ntrol, and o ffers real- time and his torical graph ical and stati stical displays .
Quick Start 1. Always rebo ot MS- Window s before installing Meg aVision- WEB. Make sure that no other MegaVisi on version is runni ng. 2. Install MegaVisi on-W EB by running "…/DISK1/setup.exe" from MegaVision-WEB CD or Insta llation Kit via "Sta rt"/"Run" functi on of MS Windows .
Please, no te the "passwo rd" is the same "p asswor d" which is use d in the MegaVision-W EB Login screen. B y default, aft er installati on the supervis or's passwor d is Empty String , so y ou may just pre ss the "Login" but ton.

Logging In When you sta rt MegaVision, you can log in as us er or s upervisor. As a user, you can view network configurat ion and device st atus, but you cannot make any cha nges in the network. As a supervisor, you ca n view network configurat ion and device stat us, a nd change configu rations and p arameters o f netw ork dev ices.
MegaVisi on allows the net work manager t o switch between SUPE RVIS OR and USER modes while the program is running. To change modes, select Logi n from t he Options menu, change modes, then choos e OK. If you choos e Cancel, the L ogin window clos es and no changes ar e made.
Using Passwords In its defa ult configuration, MegaVision req ui res a password to logi n. You can also set up the Password wi ndow to start the progra m without a password.. To Ch ange Passw ord Set tings As A User O r Supe rvisor 1. From the Opt ions menu, choos e Passwor d.
Main Wind o w The MegaV ision main window is the major gatewa y t o all monit oring and control funct ions of devices on your network . The main wi ndow contains the map/submap - t he graphical representat ion of your network. E ach device that has been correctl y added to the map appears a s an icon with its d evice n ame.
5. Copy the selected device to buffer (f or later paste) 6. Cut: copy and remove the select ed device from the map. 7. Paste previ ous ly cut/copi ed devi ce. 8. Open the Describ e window for the select ed device. 9. Open the SNMP Device Identify wi ndow for the select ed device.
Adding Background I mages You may ad d a bac kgrou nd image to the main m ap by sele cting Se lec t Bac k gr ound Im age fro m the Map menu it em. Some bitmaps ar e included with MegaV ision, or you may s peci fy your own bitma p (only the .bmp forma t is supported).
Device Main Window Each device on t he MegaVisi on map has a main window that di splays the front pa nel of that device. From thi s panel you can quickly monit or the device’s operat ions in real time. LEDs on the port image buttons indicate activity, collisions, and flow control for each port on the device.
Control Wi ndows The Device Ma in Window provides access to a set of C ontrol Windows, through which the Network Manager can perform remote control operat ions on the managed devices, change the device parameters.
Graphics Support You can graphi cally view counters data as s peedometer, li ne, or bar gra phs. These alt ernate views o f data make it easie r to an alyze and compare s tatistic s at a gl ance. A tilin g optio n allows you to neatly lin e up s everal graphi c windows on the screen.
Speedometers This type of display shows the insta ntaneous value of a selected counter in a speedometer- like window. The window contains a moving indicator, the counter category, and the current value.
Line Graphs The line gra ph feature provides a wide variet y of options for moni toring and compari ng data. In its sim ple st form , one graph for each counter is displayed in separate windows showing current act ivity.
in a new window. Figure 11b. M ultiple Line Graphs. For some s tatistic- to-grap h conve rsions, y ou will ne ed to use the mu ltiply coefficients to properly scal e graph lines , especiall y when you use two counter ca tegories, where values might have large differences.

Autodiscover y The aut odiscovery process allows you to ea sily add network devices wit hout knowing thei r IP addresses . MegaVision polls each IP address within the given ra nge and adds devices automatic ally. To star t the auto discov ery proc ess, sele ct Autodiscovery from the Mai n Window menu Map item.
Links To help you vis ua lize your network confi guration, you may add l inks between devices on t he map. Links are added manually. T o add a link, select Add Link from the Main Wi ndow menu Edit item (picture d below ). The curre nt link is highlig hted (p 3p4 in th e figure ).
General Device Inform ation: SNMP Dev ice Identify Window The SN MP De vi ce Identi fy window provides you with a quick look at basi c information about a device — i tems such a s product type, up ti me, device lo cation, and contac t. The information is retrie ved v ia SNMP according to MIB-2 (R FC-1213) spec ification .
Generic SNMP and TCP/IP Devices, Monitoring services Generic SNM P Device. The Generic SNM P Device type all ows you to mana ge any SNMP complia nt device. The Generic SNM P Device window opens when you double cli ck on a Generic device i con. This windo w is similar to the SNMP De vice I denti fy window.

MegaVision allows to monitor performance of business -critical Layer 7 network services, such as e- mail, HTTP , FTP, D NS, e tc. The se rvices are le arned auto matic ally fo r any dev ice, which is loca ted o n the map .
directory contains information how to see/modify t he full list of monitored services. You can use the s tandard MegaVis ion Graphics Support (s ee the Graphics Su pport se ction) in o rder to view the corres ponding services performance graphs. You can configure Mega Vi sion to collect t he history performance data into a file for later analysis.
A lias Manager MegaVi sion allows you t o assign ali as es to MAC addres s es, easing i d ent ificati on of network devices and stations. Each network device (a workstation, switch, hub, printer, etc) has it’s own unique 12 hexa decimal digit M AC-Address.
If there is only a vendor part of M AC address, Mega Vision will a ppend the remaini ng digits. If there is no co rrespon ding alias entry j ust the MAC add ress w ill be d isplaye d. Plea se, no te that there a re some other windows (besi des Alias Manager ), which allow assign ing al iases to MAC Addresses, e .
