Getting UDLD errors on 9300

JonFen1 — Thu, 09 Jan 2025 18:42:18 GMT

We just moved from Brocade to Meraki and some of our uplink ports are getting UDLD outbound errors on mainly the 9300. here are 2 different switches and different SFP modules and still getting the issue although we have some that are not getting any at all. We have an HPE core but I don't see how that can be the problem. Any thought or Ideas out there

I have had lots of issues with UDLD errors on the 9300. I think it has some issues in this area.

I'd turned UDLD off.

I have the same experience as well with the UDLD errors on the 9300 and have done the same.

how did you do that? I sent an email to Meraki support and they said it cannot be turned off

anyone ever hear more from Meraki on this? I too am seeing UDLD errors on the C9300 side of a EPL layer 2 link between a C9300 and a MS390.
