I have several issues in my layer2 topology. This is a mixed switch environment (Dell and Cisco). Presently one of my Dell switches is the root bridge, and I want to promote the Cisco switch ( where my servers are attached) to the root bridge. I also have some protocol mismatches;
1. the cisco switches have LLDP, CDP and fast spanning tree running.
2. the dell switches have only spanning tree running.

I have ethernet ports flapping (going up and down) on every switch. What would be the best approach to clear these issues.
