Per-VLAN Rapid Spanning Tree Groups

BLADEOS 6.5.2 Application Guide

PVRST is based on IEEE 802.1w Rapid Spanning Tree Protocol (RSTP). Like RSTP, PVRST mode provides rapid Spanning Tree convergence. However, similar to the way standard STP is enhanced by PVST+ (see “Per-VLAN Spanning Tree Groups” on page 117), PVRST is enhanced to allow per-VLAN STGs on the switch.

In PVRST mode, each VLAN may be assigned to one of 128 STGs, with each STG acting as an independent, simultaneous instance of STP. PVRST uses IEEE 802.1Q tagging to differentiate STP BPDUs.

PVRST mode is compatible with Cisco R-PVST/R-PVST+.

Configuring PVRST

This configuration shows how to configure PVRST for VLAN 1 assigned to STG 1, and VLAN2 assigned to STG 2.

1.Set the Spanning Tree mode to PVRST.

RS G8124(config)# spanning-tree mode pvrst

2.Configure port membership for each VLAN, then define the STGs for each VLAN.

By default, port 1 is a member of VLAN 1, which automatically assigned to STG 1, so no additional configuration is required for STG 1. However, for STG 2, port 2 if first added to VLAN 2, and then VLAN 2 is assigned to STG 2.

RS G8124(config)# vlan 2

RS G8124(config-vlan)# enable

RS G8124(config-vlan)# member 2

RS G8124(config-vlan)# stg 2

RS G8124(config-vlan)# exit
