Discovery Type Pane

This is the first pane of the wizard:
Figure 29 Discovery Type Pane
It allows you to specify how the list of subnets to discover is determined:
Local subnet – Select this radio button and click Next to discover only
the subnet to which the 3Com Network Director PC is attached. The
discovery process queries the operating system to determine the
subnet mask for the local subnet. The wizard moves onto the Monitor
Core Devices and Links pane. (See
Pane on page 117.) This means that you cannot specify IP ranges
when using this option. If you wish to specify ranges for the local
subnet discovery you will need to use the Specify Subnets option and
add the details of the local subnet to the list of subnets to discover.
LAN subnets connected to the default router or gateway - Select
this radio button and click Next to discover all devices on the local
subnet (to which the 3Com Network Director PC is attached) and any
additional subnets that are one router hop away (but only via LAN
connections). 3Com Network Director establishes which subnets are
one hop away by querying the default router. As with the Local
Subnet option it is not possible to specify the IP address ranges for the
subnets to be discovered.
