156 CHAPTER 5: WORKING WITH THE MAP
The map and the tree work in conjunction with each other. When you
select a device, subnet or device group within the tree it is also selected in
the map and vice versa. Once you have made your selection: you can use
the pull-right menu, in either the tree or the map, to perform an action
on that item.
Components The following section describes the principal features of the map and the
tree and the operations you can carry out from them.
Map Structure The map provides two basic views of your network topology, depending
upon whether or not you choose to view the devices in your network
grouped by subnet or as individual devices. Within each view you can
navigate around the map, and focus on particular areas of the topology
that are of interest to you.
To change from one view to another, toggle View
> Group Map by
Subnet.
The Grouped
Network View
The default view shows the devices in your network logically grouped by
IP subnet. This view is hierarchical, consisting of:
■ The top-level map — This map presents a logical layer-3 view of your
network, showing the routers and layer-3 switches, the links between
them, and which IP subnets they are logically connected to.
■ Submaps — These present logical groupings of the devices on your
network. There are two types of submap:
■ Subnets — are automatically created by 3Com Network Director
during Network Discovery, and allow you to view the network
broken down into separate IP subnets. Each subnet contains all
devices with related IP addresses.
