Feb 17, 2011 · 802.1q (standard) supports only one single instance of STP. native VLAN (Common Spanning Tree) - (let's say channel 1) one STP instance - (let's say channel 2) PVST (Cisco proprietary) Support one STP instance per each VLAN ; uses ISL trunk only. Doesn't support 802.1q

Sep 01, 2005 · With the support of IEEE 802.1Q and ISL trunking, a way was needed for interoperation between PVST and the IEEE 802.1Q concept of a single spanning tree for all VLANs. The PVST+ feature was introduced to address this requirement.

Support for Cisco's Per VLAN Spanning Tree plus (PVST+), allows a Ruckus device to run multiple spanning trees while also interoperating with IEEE 802.1Q devices. Ruckus ports automatically detect PVST+ BPDUs and enable support for the BPDUs once detected.

Enhanced PVST+ support allows a Ruckus device to interoperate with PVST spanning trees and the IEEE 802.1Q spanning tree at the same time. IEEE 802.1Q and PVST regions cannot interoperate directly but can interoperate indirectly through PVST+ regions.

Per-VLAN Spanning Tree (PVST) requires Inter-Switch Link (ISL). Per-VLAN Spanning Tree+ (PVST+) is an extension of the PVST standard. Per-VLAN Spanning Tree+ (PVST+) allows interoperability between CST and PVST in Cisco switches and support the IEEE 802.1Q standard.

Aug 25, 2006 · PVST allows the optimization of root switch placement for each VLAN and supports the load balancing of VLANs over multiple trunk links. 802.1Q is the IEEE standard for tagging frames on a trunk and supports up to 4096 VLANs.

May 28, 2017 · Behind the simple “plus” in PVST+ lurk quite subtle details that can make the difference between the two concepts very fuzzy, so the goal of this post is to give you a very brief explanation and I hope enough simple to grasp about PVST and PVST+ and their relationship with the standard IEEE 802.1q:
https://en.wikipedia.org/wiki/Spanning_Tree_Protocol
Spanning Tree Protocol standards. The first spanning tree protocol was invented in 1985 at the Digital Equipment Corporation by Radia Perlman. In 1990, the IEEE published the first standard for the protocol as 802.1D, based on the algorithm designed by Perlman.
