Re: Need Help in figuring out why these STP logs are getting Generated (Informational Logs)
Hi,
could you provide us more information?
What version of STP are you running? Is anything changed in your global config (timer)? Do you have a root configured?
Could you post the first half (before the interfaces) of "show spanning-tree"
show spanning-tree topo-change-history received
show spanning-tree topo-change-history originated
