Browsing the network

Edit online

Browse the network using the Network Views to visualize the network based on geographical or other groupings. For example, you can browse discovered subnets or device classes. Network Views also highlights discovery issues by showing you devices that the discovery was unable to access or unable to classify.

Before you begin

Before you can work with network views, the first network discovery must have successfully completed, either as part of the installation or immediately following installation.

Restriction: The Administrator user, itnmadmin, has network views assigned by default, so that when you log in with this user, you can view the topology. By default, itnmuser has OOB network views assigned, but other user profiles may not have any network views assigned by default.

Procedure

Click the Incident icon and select Network Availability > Network Views.
In the Network Views tree on the left of the widget, browse the network by expanding network view nodes of interest.
Here are some examples:
- To browse subnets, click the + symbol next to the Subnets node.
- To browse VLANs, click the + symbol next to the Global VLANs node.
- To browse device classes and see devices grouped into categories such as Linux™, Sun, and Cisco, click the + symbol next to the Device Classes node.
  Note: Devices which the discovery process could not access using SNMP appear in the NoSNMPAccess sub-node, under the Device Classes node.
Click a network view.
The network map displays subnets and devices in that network view. Faulty devices are displayed with an associated event icon.
