Now, PVST and PVST-Plus were proprietary spanning tree protocols that accommodated multiple VLANs. So, you can tune them basically on a VLAN by VLAN basis. Now, the concepts in PVST and PVST-Plus were standardized in the 802.1w specification, Known as the Rapid Spanning Tree Protocol or RSTP for short now RSTP includes other enhancements to help improve Convergence and so let's kind of go through what those look like. So the first thing is the RSTP port states have changed So the first port state is the discarding and in this state the switch ports can be enabled But the port does not forward any traffic to ensure a loop is not created Now the state combines the early port states of disabled blocking and listening So, BPDUs are going to be received and transmitted while in a discarding state.
