Hello ! 

 

I have a problem of my network, when i change PVST to PVRST, the addresses of the switches are removed after 3sc. I learned that when RSTP detects au topolgy change, It flushes the MAC addresses associated with all these ports.


Ok but i don't understand the problem on my network, why he detects a topology change ? It's a problem or it's normal ?

And this command on the Switch 4 and 3:

Sorry if my english is a bit broken,

 

Thanks for your help
