Adding an NTA data source device
You can add devices as data sources for NTA using the Add feature on the Device Management page.
However, you must be an administrator to add, modify, or delete devices that are used as data sources
in NTA.
To add an NTA data source device:
1. Select Service > Traffic Analysis and Audit > Settings.
2. In the Settings area of the Traffic Analysis and Audit page, click the Device Management link.
NTA displays all devices that are data sources for the NTA service module in the Device List
displayed in the main pane of the Device Management page.
3. Click Add.
The Add Device page appears. You can add data source devices by adding devices manually or
by selecting devices from the IMC Platform.
• If you add data source devices manually, the devices do not consume licenses of the IMC
Platform. However, you cannot manage these devices, including monitoring performance,
configuring backups, and receiving syslog or trap packets from parsing devices.
• If you add data source devices by selecting devices from the IMC Platform, you can manage
the devices by using the basic network management function of the IMC Platform. However,
these devices consume licenses of the IMC Platform. For more information about adding
devices to the IMC Platform, see IMC Intelligent Management Center v7.1 Enterprise and
Standard Platform Administrator Guide .
After you have added a device to NTA as a network flow data source, in order for it to become available
for analysis task configurations and reporting, you must also select it by using the NTA Server
Management feature. For more information about selecting a device by using the NTA Server
Management feature, see " Managing NTA servers ," specifically " Modifying an NTA server
configuration ."
You must also configure the device to forward NetStream, NetFlow, or sFlow traffic to the NTA server. For
more information about configuring a router or switch to forward NetStream, NetFlow, or sFlow data to
a collector, see the vendor documentation. For more information about configuring the NTA server as a
collector, see "
Managing NTA servers ."
Adding data source devices manually
To add data source device manually:
1. In the Device IP field, enter the IP address of the device.
Make sure the IP address communicates with the NTA server correctly. You cannot modify this field
after you have specified it.
2. In the Name field, enter the name of the device.
You cannot modify this field after you have specified it.
3. In the Description field, enter the description for the device.
4. In the SNMP Community field, enter the SNMP Read community string of the device.
