MegaVision Network Management System - Manual (Page 45)

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. 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 Describe window displays with the
newly defined interface inserted above the highlighted line.
11. Choose OK in the Describe 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.
Modifying Device Settings.
After a device has been added, you can change set-up parameters or add/modify/delete an
interface through the Describe window.
Deleting Devices .
You can remove a device from a map via Main Window Edit/Delete menu item. You can also
select the desired device and press the Del key on your keyboard.
Submaps
MegaVision allows you to add a submap type icon to any map, easing visualization of your
network. Please note that terms “map” and “submap” means the same in this manual. You
can add any device type in a submap, including other submaps. To open a submap, double-
click on its icon. The submap from which it was called is automatically added, enabling you
to quickly navigate between maps. You can also jump between different submaps by adding a
submap and giving it the name of the map you want to jump to. You can also use the Open
Map window to Open/Add/Delete maps.
