We have several switches sending STP traps to iMC reporting ports blocked and offline then online. After verifying that physical loops do not exist on these switches I turned to google and found that an end-point power cycle can sometimes cause the switch port to vet for a potential loop and do a quick block/offline/online and then once verified as a non-loop - leave the port in an enabled/forwarding state not withstanding sending traps for this loop-test to my iMC. From what I understand this is normal and by design.
My problem is: that I want to receive legit loop traps, but I don't give a rip when the switch is vetting a port but both scenarios send the same trap message to iMC. So it looks like I have to weed through the vetting traps to actually find the rare legit loop. Is there a way to filter the vetting traps and continue to receive the actual loop traps?
Thanks for any assistance
