[Linkk]

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

[shinepothen]

Thank you for the reply

I am attaching the show output

MRF-DC-CORE-SW# show spanning-tree topo-change-history received
