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 Table 2-9, SNMP Credentials.

Table 2-9 SNMP Credentials

	Field	Description
	Mode: No Auth, No Priv	SNMP will be used in a mode with no authentication and no
		privacy.
	Mode: Auth, No Priv	SNMP will be used in a mode with authentication, but no
		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.
	Auth Password	Enter the authentication password associated with the
		username that was configured on the device. Verify the
		password.
	Auth Algorithm	Choose the authentication standard which is configured on
		the device (MD5 or SHA-1).
	Privacy Password	Enter the privacy password, which is configured on the
		device. Verify the password.
	Privacy Algorithm	Enter the privacy algorithm, which is configured on the
