Yes, we have got the detailed info. Thanks for your immediately response.
1. According to the memory log, we found that port 1/0/29 and 2/0/29 is flapping. Could you please double check these two port status?
2. According to spanning tree log, there is loop topo change. Could you please provide the network topo to us for further analysis?
3. I am afraid the traffic wasn't interrupted by these spanning tree log, right? As I think these log is normal, just dut to STP protocol detect topo tree changing, and adjust forwarding path.
OK I just sent what I could AND
Note on my switch there are not options for ' full memory dump ' and ' crash logs ' . In case you have a suggestion for those.
thank you for the help so far!

The proxmox system attached to that lag was having cluster communication issue.
I rebooted it and it has been OK for now as far as cluster. But we have been having off and on issues with that cluster. It occurs often when I was testing our 3 port lags [ see other thread ]. When I'd plug patch cable in to 3/0/1 , this cluster and some vm's would have time and network connect issues.
Per another thread it looks like we should use lag has mode 3 instead of 6 .
AND
could you teach me how to find the log that shows port flapping? I want to monitor that after changing the hash mode.
I figured out how to see the logs - create and download tech support file.
Will use the file to check and correct flapping. I'll report back in a few days or so.
