I reade in the documentation that the Path Cost have to 4 for a port in 1000M. But on my network, i have a lot of Port that have a Path Cost to 19 or 100 in 1000M.If i change manually this information, the path coth change automatically after a few seconds.
I would like to know if it's a real problem, and how can i change this information?
Thanks a lot!
One of the first things I would suggest doing is to ensure the switch firmware is up to date, this will help ensure the switch is running as smooth as it can.
Page 261 of the user guide starts the spanning tree commands, including costs. I would read through these commands to ensure the proper commands are being run.
Here are some good articles on spanning tree.
If you are still seeing the same issue after looking through this material and steps. If you can supply us with what commands you are running, and the output you are seeing after running these commands.
