Dear Sir, We are experiencing a discrepancy in interface status monitoring, where interfaces are showing an issue in SolarWinds, despite all services (ping, browsing, etc.) functioning normally. We have already engaged our hardware vendor (Sophos) to investigate potential hardware issues. After thorough analysis, Sophos confirmed that there are no hardware-related problems on their end. Given this, we kindly request your assistance in troubleshooting this issue within SolarWinds. What could be the cause of this discrepancy between actual network performance and the interface status reported by SolarWinds? How can we resolve this issue and ensure accurate interface status monitoring in SolarWinds? This discrepancy is causing concern, as management is inquiring about the persistent interface status issue despite the absence of any actual service disruptions. We appreciate your prompt attention and assistance in resolving this matter.

Why this interface is going critical ?

What is the media on the link, is it copper, is it fiber optic? Do you have a bad cable, dirty fiber optic? Have the cables been tested? Is the interface on the device showing any errors at the device level itself? Have you tried looking at the traffic with a packet sniffer? Are you getting a ton of TCP retransmits?

The reason are discarded packets on the interface. This is often caused by incorrect VLAN settings/congestion situations or others.
if this is an external interface (which I suspect) I would either switch off discard packages completely (this will unfortunately also switch off error packages) or set the threshold to a high enough level where it does not trigger any error
