23. Spanning Tree Protocol 23 This chapter provides the following examples: • Configure Classic STP (802.1d) • Configure Rapid STP (802.1w) on page 352 • Configure Multiple STP (802.1s) on page 353 The purpose of Spanning Tree is to eliminate loops in the switch system. There are three STPs: Classic STP (802.1d), Rapid STP (RSTP, 802.1w), and Multiple STP (MSTP, 802.1s). While STP can take 30 to 50 seconds to respond to a topology change, RSTP is typically able to respond to changes within a few seconds. RSTP can revert back to 802.1d in order to interoperate with legacy bridges on a per-port basis. This drops the benefits it introduces. In Multiple Spanning Tree Protocol (MSTP), each Spanning Tree instance can contain several VLANs. Each Spanning Tree instance is independent of other instances. This approach provides multiple forwarding paths for data traffic, enabling load balancing, and reducing the number of Spanning Tree instances required to support a large number of VLANs. Configure Classic STP (802.1d) The example is shown as CLI commands and as a Web interface procedure.

Spanning Tree Protocol

This chapter provides the following examples:

•

Configure Classic STP (802.1d)

•

Configure Rapid STP (802.1w)

on page

352

•

Configure Multiple STP (802.1s)

on page

353

The purpose of Spanning Tree is to eliminate loops in the switch system. There are three

STPs: Classic STP (802.1d), Rapid STP (RSTP, 802.1w), and Multiple STP (MSTP, 802.1s).

While STP can take 30 to 50 seconds to respond to a topology change, RSTP is typically

able to respond to changes within a few seconds. RSTP can revert back to 802.1d in order to

interoperate with legacy bridges on a per-port basis. This drops the benefits it introduces.

In Multiple Spanning Tree Protocol (MSTP), each Spanning Tree instance can contain

several VLANs. Each Spanning Tree instance is independent of other instances. This

approach provides multiple forwarding paths for data traffic, enabling load balancing, and

reducing the number of Spanning Tree instances required to support a large number of

VLANs.

Configure Classic STP (802.1d)

The example is shown as CLI commands and as a Web interface procedure.
