Rapid Per-VLAN Spanning-Tree (PVST+) Cisco Switch Configuration

- Instance of RSTP per VLAN
- Improves detection of indirect failures over classic spanning tree (802.1D)
- Even if network doesn't have any layer 2 loops you still should enable spanning tree for protection against unexpected layer 2 loops

Switch(config)#spanning-tree mode rapid-pvst
