OI Group Latency alerts not appearing in Spectrum Events due to loopback agent-address

Issue/Introduction

OI Group Latency alerts sent from DX NetOps Performance Management reach the SpectroSERVER but do not appear in the OneClick Events tab. This occurs because the incoming SNMPv1 traps carry a loopback address (127.0.0.1) in the agent-addr field, which Spectrum ignores by default.

Cause

Spectrum correlates SNMPv1 traps using the agent-addr field in the PDU. If this field contains 127.0.0.1 or 0.0.0.0, the SpectroSERVER drops the trap to prevent incorrect mapping to the loopback interface of the server itself.

Resolution

Configure the Spectrum model to map traps using the packet's network IP header instead of the PDU agent-addr field:

1. Locate the device or EventAdmin model in the OneClick Explorer tab.
2. Select the model and click the Attributes tab in the Component Detail panel.
3. Search for the attribute map_traps_to_this_model_using_IP_header (Attribute ID: 0x12a6d or 0x3dc000b).
4. Change the value to Yes.
5. Trigger a test trap to verify the event now appears on the model.
