many of these in log "Spanning Tree Topology Change Received"
Hello
at Monitoring > lags , lag 11 has had some "Packets received with Errors" . now there are about 20. last week 8 .
so I set up logging to go to a rsyslog server . just lag 11 has entries [ besides login/logout ] . the
here are some:
Jul 11 10:23:22 169.254.100.100-1 TRAPMGR[51016628]: traputil.c(658) 1710 %% Spanning Tree Topology Change: 0, Unit: 1 Jul 11 10:23:21 169.254.100.100-1 TRAPMGR[155922352]: traputil.c(658) 26719 %% Spanning Tree Topology Change Received: MSTID: 0 lag 11 Jul 11 10:23:21 169.254.100.100-1 TRAPMGR[155922352]: traputil.c(658) 26720 %% Spanning Tree Topology Change: 0, Unit: 1 Jul 11 10:23:23 169.254.100.100-1 TRAPMGR[155922352]: traputil.c(658) 26721 %% Spanning Tree Topology Change Received: MSTID: 0 lag 11 Jul 11 10:23:53 169.254.100.100-1 TRAPMGR[155922352]: traputil.c(658) 26722 %% Spanning Tree Topology Change Received: MSTID: 0 lag 11 Jul 11 10:23:53 169.254.100.100-1 TRAPMGR[155922352]: traputil.c(658) 26723 %% Spanning Tree Topology Change: 0, Unit: 1 Jul 11 10:23:55 169.254.100.100-1 TRAPMGR[155922352]: traputil.c(658) 26724 %% Spanning Tree Topology Change Received: MSTID: 0 lag 11
the lag target is a M4100-50G-POE+ . lag hash mode = 6 .
Question - could I have suggestions on how to fix that?
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.

Hi robfantini,
Welcome to the community!
These spanning tree log is due to topo change, please check whether there is port flapping or not in the switch?
Hope it helps!
