To verify the bridge priority of a switch, use the show spanning-tree command. In Example 3-4, the priority of the switch has been set to 24,576. Also notice that the switch is designated as the root bridge for the spanning-tree instance. Example 3-4 Verifying the Root Bridge and BID
Per VLAN Spanning Tree + (PVST+) – It is a spanning tree standard developed by Cisco for its devices which finds the root bridge per VLAN. It is a Cisco default version of STP. It finds separate 802.1d spanning tree instance for each VLAN. It also provides backward comparability with 802.1d or CST. What are Spanning Tree Bridge Priority (Switch Priority Every Bridge (Switch) Participating in a Spanning Tree Protocol network is assigned with a numerical value called Bridge Priority (Switch Priority) Value. Bridge Priority (Switch Priority) Value is a 16-bit binary number. By default, all Cisco Switches has a Bridge Priority (Switch Priority) value of 32,768.

Because Spanning Tree Protocol operates on Layer 2 of your network, you can enable this feature without any impact to Firebox performance. In a Spanning Tree implementation, your network topology has a tree structure. A root bridge switch is located at the bottom of the tree.
