Requirements for a Topology Discovery on page 609
The NSM Topology Manager is a tool provided in the NSM GUI that allows you to discover
and manage the physical topology of a network of devices connected to a Juniper
Networks EX Series Ethernet switch. The networkcan include J Series, M Series, MX Series,
and EX Series devices, as well as ScreenOS and IDP devices, IP phones, desktops, printers,
and servers. The Topology Manager also provides details about connections between a
device and the EX Series switch.
To use the Topology Manager, first add one or more EX Series switches to the device
manager in NSM. You can then use an added device as a seed device in initiating a
topology discovery.Alternatively, if there are no devices added or managed in NSM, you
can initiate a topology discovery by configuring preferred subnets; with this method, NSM
discovers all the IP addresses in the included subnets range.
In addition to having either a seed device or configuring preferred subnets, you also need
the following to initiate topology discovery:
The management IP address of the EX Series switch that acts as the seed IP address

SNMP credentials:
