4.4.9 Network monitoring configuration

You can monitor the network to control network connection for devices. You can also automatically block the network connections of computers which are determined to have insufficient security measures. The following figure shows a system configuration in which network monitoring is used.

[Figure]

To monitor the network, you must install an online managed computer with the network monitor enabled (computer that monitors the network) for each network segment.

Do not clear the following check boxes in the Basic settings in the agent configurations assigned to the computer that monitors the network.:

Communicate with the higher system
Periodically notify the higher system of the information collected from the computer

In the Network List view of the Inventory module, select one computer for each network segment group (for each broadcast domain), and then enable the network monitor.

Important: When you use the network monitor, NX NetMonitor and JP1/NETM/NM cannot be used with JP1/IT Desktop Management 2. Before using the network monitor, you must first uninstall any instances of NX NetMonitor and JP1/NETM/NM from the computers within the network segment.

Tip

When you enable the network monitor for a computer, the network monitor agent is installed on that computer.

You can also install JP1/IT Desktop Management 2 - Network Monitor on the online managed computer from the distribution media, and then enable the network monitor.

If the network monitor is enabled, a computer that is newly connected to the network is automatically discovered, and network connections within the network segment are controlled according to the network monitor settings. Note that the network monitor can be enabled on only one computer in a network segment.

Tip: Ensure that the computer with the network monitor enabled is running 24 hours a day. While the computer is turned off, the network monitor cannot control network connection nor discover devices.

Tip

You can join multiple VLANs (Virtual LANs) by using the VLAN trunk connection function to monitor multiple subnetworks (VLANs) on a single computer (and a single network card), provided that the following prerequisites are satisfied.

The network card of the computer that monitors the network supports EEE 802.1Q (VLAN).
Tagged VLAN and trunk connection (passing multiple VLANs) can be set on the port of the switch to which the computer that monitors the network is connected.
