following attributes:
The Customer Name key builder requires configuration in the config/vpn.conf file. You must include
one row to correspond to each PE device VPN interface that export NetFlow packets to this NFC server.
The rows in this file contains five fields, in the following order: exporting device (PE) IP address,
interface name, name of the site to which this interface is connected, CE to which this interface is
connected, and customer name. These fields should be separated by commas. See the following example:

The exporting device (PE) IP address and interface name fields are required. You can include empty
strings for the remaining fields in each row if those fields do not need to be resolved. For example, if you
do not need to specify a site name, the site name fields can be left empty.
