4.6 Spanning Tree Protocol 

4.6.1 Theory 

The Spanning Tree Protocol can be used to detect and disable network loops, and to provide backup links between switches, 

bridges or routers. This allows the switch to interact with other bridging devices in your network to ensure that only one route 

exists between any two stations on the network, and provide backup links which automatically take over when a primary link 

goes down. The spanning tree algorithms supported by this switch include these versions:   

 

STP – Spanning Tree Protocol (IEEE 802.1D)   

 

RSTP – Rapid Spanning Tree Protocol (IEEE 802.1w)   

 

MSTP – Multiple Spanning Tree Protocol (IEEE 802.1s) 

 

The 

IEEE 802.1D Spanning Tree

 Protocol and 

IEEE 802.1w Rapid Spanning Tree

 Protocol allow for the blocking of links 

between switches that form loops within the network. When multiple links between switches are detected, a primary link is 

established. Duplicated links are blocked from use and become standby links. The protocol allows for the duplicate links to be 

used in the event of a failure of the primary link. Once the Spanning Tree Protocol is configured and enabled, primary links are 

established and duplicated links are blocked automatically. The reactivation of the blocked links (at the time of a primary link 

failure) is also accomplished automatically without operator intervention. 

 

This automatic network reconfiguration provides maximum uptime to network users. However, the concepts of the Spanning 

Tree Algorithm and protocol are a complicated and complex subject and must be fully researched and understood. It is possible 

to cause serious degradation of the performance of the network if the Spanning Tree is incorrectly configured. Please read the 

following before making any changes from the default values. 

The Switch STP performs the following functions: 

 

Creates a single spanning tree from any combination of switching or bridging elements. 

 

Creates multiple spanning trees – from any combination of ports contained within a single switch, in user specified 

groups. 

 

Automatically reconfigures the spanning tree to compensate for the failure, addition, or removal of any element in 

the tree. 

 

Reconfigures the spanning tree without operator intervention. 

Bridge Protocol Data Units 

For STP to arrive at a stable network topology, the following information is used: 

 

The unique switch identifier 

 

The path cost to the root associated with each switch port 

 

The port identifier 

 

STP communicates between switches on the network using Bridge Protocol Data Units (BPDUs). Each BPDU contains the 

following information: 

 

The unique identifier of the switch that the transmitting switch currently believes is the root switch 

 

The path cost to the root from the transmitting port
