Cisco-SDWAN BFD SNMP traps display incorrect IP address values in DX NetOps Spectrum

Products

• Network Observability

Issue/Introduction

You observe that SNMP traps from the Cisco-SDWAN BFD MIB do not display IP address variables correctly within the DX NetOps Spectrum Events console. While Cisco provides the latest MIB, variables such as ciscoSdwanBfdSourceIp, ciscoSdwanBfdDestinationIp, ciscoSdwanBfdLocalSystemIp, and ciscoSdwanBfdRemoteSystemIp appear as unreadable or incorrectly formatted strings.

Environment

Spectrum Any

Cause

This issue occurs because the variables are mapped as String values ({S n}) in the Event Format file. Since the MIB defines these variables as the InetAddressIP type, the String format is incompatible and fails to decode the Octet-based IP information properly.

Resolution

To resolve this display issue, you must update the variable mapping in the Event Configuration to use the correct data type:

1. Open the Event Configuration editor in DX NetOps Spectrum.
2. Locate the specific event associated with the Cisco-SDWAN BFD traps.
3. Identify the varbinds for the IP addresses (typically varbinds 2, 3, 7, and 9).
4. Modify the mapping in the Event Format file by changing the S (String) prefix to O (Octet) for each identified variable:
   • Change {S 2} to {O 2}
   • Change {S 3} to {O 3}
   • Change {S 7} to {O 7}
   • Change {S 9} to {O 9}
5. Save the changes in the Event Configuration editor.
6. Refresh the view in OneClick by navigating away from the device and then back to it.

If the values still do not display correctly as Octets, you can alternatively try mapping them as Type IP Address using the A prefix (e.g., {A 2}).
