Overview

The BGP tab all chart does not display data in the NTA Web Console.

Environment

All NTA versions

Cause 

The devices are not configured to send the Autonomous System numbers (ASN) in the flows.

 

Resolution

 

  1. Install Wireshark on the system.
  2. Start the Packet Capture Wizard. 
  3. Select the interface you would like to capture traffic.
  4. Apply a capture filter to only see the net flow traffic.
    Sample filter for the default port which is 2055.
  5. Leave the trace to run for 15 minutes.
  6. You can apply the following display filters to check for the ASN:
    1. cflow.srcas != 0  (Filter for source address not equal to 0)
    2. cflow.dst != 0      (Filter for source address not equal to 0)
  7. If you have BGP configured, you will see the traffic displayed.
  8. Configure the device to send BGP in the flows. Please contact your device vendor for full procedures for your specific devices.
