Why are some interfaces labeled as IfIndex2,IfIndex3, etc.?
This happens if the device/interface has not responded to the SNMP requests sent by NetFlow Analyzer. Check the SNMP settings of the interface or manually edit the interface name from the Dashboard. NetFlow Analyzer uses port 161, and the public community string as default SNMP values. If the SNMP settings of your device are different, change the vaues in the Dashboard Interface View. If you need to change this globally, enter the new values in the same fields under Settings.
