Clearing a udld tx/rx loop detection error

stevestewart1 — Thu, 27 Jun 2024 16:20:50 GMT

We had an udld tx/rx loop detection error a few weeks ago that has been resolved but the port that it occurred on is still showing that error even though nothing is plugged up to it, is there a way to clear this error message so the port will no longer show orange and show the warning...?

I was able to clear it by bouncing the port

I am sorry I am not sure what that is or how to do that could you please explain it?

unfortunately, that did not work, I even plugged my laptop into that port and cycled the port and it shows my laptop connected to it but still has the orange color and the UDLD notification for that port

Have you checked to make sure there isn't a problem with the cabling?

Note that sometimes there may be a delay in dashboard information updates.

The cabling should not be an issue, I have a desktop connected directly to that port on the switch now, you are correct about it taking some time to update the cloud with changes so I am going to leave the desktop plugged into the port for the rest of the day and evening to see if it makes any difference, thank you all for the replies and I will repost tomorrow on any status positive or negative

Hello all, I am also experiencing this same issue clearing a UDLD error on a specific port. I have removed the loop, connected another device to this port and it is still amber on the port list. How do I remove this notification? I have bounced the port. Bounce the SW next?

Bouncing or restarting the Switch during an upgrade to the Firmware fixed the issue for me, I would recommend the restart of the switch but would only do it during an upgrade and planned maintenance, to avoid network interruptions,

I found that even though it was showing a loop there was no impact to my environment, I hope this helps and I hope that a restart will get rid of that pesky

Amber port indicator for you too.

Hi Team,

I have also been observing the same issue for the past 10 days on the specific interface where the WAN link is terminated. All services are functioning normally, and the link appears to be stable with no impact on performance. However, the Meraki portal continues to generate alerts for this interface.

Requesting your support to investigate and advise on the next steps.
