Hello,

you can use the root guard feature to prevent any new switch to become root:

"Spanning Tree Protocol Root Guard Enhancement"

In addition make sure you do not run into VTP issues (like deleting all VLANs) following f.e. this guideline:

"Adding a VTP Client Switch to a VTP Domain"

Hope this helps!

Regards, Martin
