Actually the job of root guard is to errdisable any links that receives a superior BPDU in order to protect the root. Just a friendly reminder that it could lead to traffic loss or silo'd switches in the real world :)

Hi I am using the Proctor lab Switches and they are all 3560, and I can still lower priority on cat 3 when I configured root guard on Cat 1. The job of the root guard is to prevent any other switches from becoming root bridge. Any definition why I can lower priority on Cat 3 all though I configured root guard on CA1?
