Saving and Opening
Maps
To create a new empty map file and launch the Network Discovery wizard
select File > New. You are prompted to save the map if the current map
has changed.
Saving the map stores all of the information about the current map to a
set of map files. These include such information as:
■ The devices in your network and their attributes.
■ The topology of your network and how it is laid out within the map.
■ The events associated with your network.
■ Navigation details, including the currently viewed submap and the
zoom levels and pan settings for all submaps.
■ The options currently selected in the Tools > Options dialog box and
the View menu.
If you choose to either exit 3Com Network Director or open another map,
3Com Network Director may prompt you to save the map. This will occur
if:
■ The map was newly created and has never been saved.
■ Any of the above information has changed since the map was last
saved.
If you intend, in the future, to manage the same portion of network that
is currently discovered in the map 3Com recommends that you save the
map. This will prevent you having to rediscover that portion of network
when you next wish to view it.
It is good practice to save your map at regular intervals. To do this select
File
> Save. If the map is a newly created map and has never been saved
then you will be prompted for a file name to save the map files under. If
you have already saved the map and wish to save it under a new name,
select File
> Save As, which will prompt you for a new file name.
If you make changes to the above information in a map that you have
opened, or if you create a new map, and you do not subsequently save it,
then all the information associated with the map will be lost.
