Submaps can contain shortcut symbols, that indicate that the device
that is linked to is not contained in the current map. For more
information see
“Shortcut Symbols” on page page 186 .
There are various methods that can be used to navigate between the
top-level map and its submaps. For more information see
“Navigation”
on page 182 .
The Ungrouped
Network View
When you choose to view the devices in your network without grouping
them by subnet, 3Com Network Director displays the layer-2 (physical)
topology of your network in a single top-level map containing all of the
devices discovered on your network. This view does not show:
■
The subnets in your network. Consequently links from routers and
layer-3 devices to the subnets they are logically connected to are not
shown. In this view the devices that are contained within the subnets
are shown in the top-level map.
■
The device groups in your network. Any device groups within your
network are expanded within this view so that the devices they
contain are shown in the top-level map.
Devices
Each icon on the map represents a device on your network that has been
discovered by 3Com Network Director through use of the
Network
Discovery wizard, or has been added to the map manually. For more
information see “The Network Discovery Wizard” on page 109 . For
information about adding single devices to the map see “Adding Items to
the Map” on page 202 .
If you are only interested in your network infrastructure, and do not wish
to view the end stations on your network then turn off the
View
>
Show
End Stations option. This will simplify the contents of your map by hiding
all of the end stations. If you turn off this option then you may also wish
to relayout your map. For more information see
“Modifying the Map
Layout” on page 200 .
Device Icons
Each of the basic icons used to represent devices on your network has an
image contained within it to show the type of device represented.
