About Topology Manager Preferences
The topology discovery engine performs a topology discovery according to your
preferences. Clicking
Preferences
in the tool bar opens the Topology Preferences Dialog.
The topology preferences dialog has three tabs:
•
Default Credentials Tab on page 642
•
Refresh Interval Tab on page 642
• Preferred Subnets Tab on page 642
Default Credentials Tab
This tab contains a table where each row represents a set of credentials that you can
add or delete. The topology discovery engine uses default SNMP settings in the absence
of specified SNMP settings. You cannot delete credential SNMP version 1 or version v2c
with the community string “public”, because NSM uses it as the default setting. When
adding credentials, you must specify a community string if you choose versions SNMPv1
or SNMPv2c. If you choose version SNMPv3, then you also need to specify the following
parameters:
•
USM User Name
•
Authentication Type and Password
• Privacy Type and Password
Refresh Interval Tab
This tab allows you to set the interval at which the topology discovery engine must
discover the network topology. You can set a particular time of day or regular intervals.
The time of your initial discovery serves as the basis of calculation for future discoveries.
Preferred Subnets Tab
This tab allows you to specify whether a particular subnet is to be explicitly included in
the discovery. You can specify a list of allowed and denied subnets. You must specify
included subnets because topology discovery happens only for those included subnets
that you configure. Discovery does not take place if there are neither included subnets
nor seed devices (managed devices). If you configure both included and excluded subnets,
discovery happens only for included subnets and not for excluded subnets. When adding
a subnet to either the allowed or denied list, specify the subnets base IP address and the
subnets mask number.
Adding Discovered Devices to NSM
After a topology discovery, you can view a list of M Series, MX Series, J Series, EX Series,
IDP, and ScreenOS devices that are not yet managed by NSM by selecting the
Manager
Map
tab. You can add any of the devices on the list to NSM by following these steps.
1.
Select and right-click on a device in the map. NSM launches a wizard to help you add
devices to be managed.
