Spanning Tree Topology Change Connect resets
we are having some issues with our network being extremely slow. and after running wireshark I see a lot of RST (connect resets) which I believe is bad. I ran the command show log on our DELL 6248 switch stack and I see Spanning Tree Topology changes.
<189> OCT 01 04:56:10 192.168.0.3-1 TRAPMGR[125616720]: traputil.c(611) 1 %% Spanning Tree Topology Change: 0, Unit: 1
<189> OCT 01 04:58:12 192.168.0.3-1 TRAPMGR[125616720]: traputil.c(611) 2 %% Spanning Tree Topology Change: 0, Unit: 1
<189> OCT 01 05:06:12 192.168.0.3-1 TRAPMGR[125616720]: traputil.c(611) 3 %% Spanning Tree Topology Change: 0, Unit: 1
the date/time is wrong but that's what happening. How can I fix this?

Hi,
Try updating the firmware, https://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=CMXJ0&fileId=3462552503&osCode=NAA&productCode=powerconnect-6224&languageCode=EN&categoryId=NI
Is it showing which ports are changing? What does this switch connect to? Try turning off portfast.

I'm not seeing any port actually being listed as blocked. I ran no spanning-tree portfast on 1/g1 (connects to another switch)..
1/g45 (connects to firewall)
2/g43 connects to an access point..
this switch stack was setup to eliminate the other switches throughout and we have yet to transition everything over...
as for updating the firmware.. I can't do that until the weekend. This is a production environment and they don't seem to be having issues. I think at the moment I'm the only one that sees it as a big issue. Others just see it as a little slow.
Have anything else to check aside from updating firmware?

The other thing to do is to do the show spanning tree active after each change and see if you can isolate which port, it could be a connection issue on a specific port causing it to go up and down.

Does this mean the two ports listed are looped somehow?

This new switch stacking is connected to a series of other switch (being phased out)
I started checking cables and discovered 2 cables connecting two switches together so I removed the one and now I only see port 30 listed. which leads me to believe there is another loop somewhere.
Would this be correct? I have check the cables on these two switch but maybe there is a loop coming from one of the other switch throught this building.

It does sound like there may be another loop based on what you described.
