STP Commands

This chapter describes commands for: 

Creating, configuring, enabling, and disabling Spanning Tree Protocol (STP) on the 

switch

Enabling and disabling Rapid Spanning Tree Protocol (RSTP) on the switch

Enabling and disabling Multiple Spanning Tree Protocol (MSTP) on the switch

Displaying and resetting STP settings on the switch

STP

STP is a bridge-based mechanism for providing fault tolerance on networks. STP is a part of the 
802.1D bridge specification defined by the IEEE Computer Society. To explain STP in terms 
used by the 802.1D specification, the switch is referred to as a bridge.

STP allows you to implement parallel paths for network traffic and ensure that redundant paths 
are:

Disabled when the main paths are operational.

Enabled if the main path fails.

RSTP

The Rapid Spanning Tree Protocol (RSTP) IEEE 802.1w provides an enhanced spanning tree 
algorithm that improves the convergence speed of bridged networks. RSTP takes advantage of 
point-to-point links in the network and actively confirms that a port can safely transition to the 
forwarding state without relying on any timer configurations. If a network topology change or 
failure occurs, RSTP rapidly recovers network connectivity by confirming the change locally 
before propagating that change to other devices across the network. For broadcast links, there is 
no difference in convergence time between STP and RSTP. 

RSTP supersedes legacy STP protocols, supports the existing STP parameters and 
configurations, and allows for seamless interoperability with legacy STP.
