Step 6 (Optional) If you know the specific value of the Engine ID on the device you would like to monitor,
check the “Engine” check box, and enter the value of the Engine ID. If the “Engine” check box is left
unchecked, then all NDE records exported by the device will be grouped into the same data source,
regardless of the Engine ID populated in the NDE packets (in most cases the Engine check box can be
left blank and you don't have to worry about the Engine ID value).
Some devices have multiple Engines which independently export NDE records. For example, on some
Cisco routers, NDE records can be exported by the Supervisor module as well as individual line cards.
The packets exported may have the same source IP address, but the Engine ID exported by the Supervisor
will be a different value than the Engine ID(s) exported by the line card(s). If you want to include only
one Engine in the data source, you must check the “Engine” box and provide the value of that Engine ID.
Step 7 (Optional) SNMP v1/v2c RO Community String: If SNMP v1 or v2c will be used to communicate with
the device, enter the community string that is configured on the device that is going to export NetFlow
packets to the NAM.
Step 8 (Optional) “Enable SNMP v3”: If SNMP v3 will be used to communicate with the device, fill in the
fields within the v3-specific dialog.
Step 9 (Optional) If desired, fill in the SNMP credentials for the device. If valid SNMP credentials are provided,
the NAM can upload readable text strings from the device to describe the interfaces on that device rather
than just displaying the interfaces as numbers. You may specify either SNMPv2c or SNMPv3
credentials. See Tabl e 2-9, SNMP Credentials.
Step 10 Click the Submit button.

privacy.
Mode: Auth and Priv SNMP will be used in a mode with both authentication and
privacy.
User Name Enter a username, which will match the username
configured on the device.
