Configuring Rapid PVST+

Rapid per VLAN Spanning Tree (Rapid PVST+) is an updated implementation of STP that allows you to
create one spanning tree topology for each VLAN. Rapid PVST+ is the default Spanning Tree Protocol
(STP) mode on the switch.
Spanning tree is used to refer to IEEE 802.1w and IEEE 802.1s. If the text is discussing the IEEE 802.1D
Note
Spanning Tree Protocol, 802.1D is stated specifically.
This chapter describes the configuration of Rapid PVST+ on Cisco Nexus 3000 Series switches. It includes
the following sections:

Information About Rapid PVST+

The Rapid PVST+ protocol is the IEEE 802.1w standard, Rapid Spanning Tree Protocol (RSTP), implemented
on a per VLAN basis. Rapid PVST+ interoperates with the IEEE 802.1D standard, which mandates a single
STP instance for all VLANs, rather than per VLAN.
Rapid PVST+ is enabled by default on the default VLAN (VLAN1) and on all newly created VLANs in
software. Rapid PVST+ interoperates with switches that run legacy IEEE 802.1D STP.
RSTP is an improvement on the original STP standard, 802.1D, which allows faster convergence.
Note Spanning tree is used to refer to IEEE 802.1w and IEEE 802.1s. If the text is discussing the IEEE 802.1D
Spanning Tree Protocol, 802.1D is stated specifically.
