Spanning Tree Protocol

[Supertech26]

I need basic and simple explanation for

1) root bridge

2) non root bridge

3) root port

4) designated port

5) blocking port

6) There is three switches with same mac address ( 0001.C714.6038) and which one of this will be root bridge, non root bridge, root port, designated port, blocking port.

i. There is no possibility with same mac address for 3 switches.Even vendor can t be make the product as each vendor has unique MAC code. The root bridge election is combination of lowest bridge ID and MAC address. If the bridge ID is equal on all switches then it will look into ti lowest mac address which are unique.
