18. STP

This chapter describes the following topics:

• Overview on page 520

• Spanning Tree Domains on page 526

• STP Configurations on page 538

• Per VLAN Spanning Tree on page 544

• Rapid Spanning Tree Protocol on page 545

• Multiple Spanning Tree Protocol on page 557

• STP and Network Login on page 569

• STP Rules and Restrictions on page 571

• Configuring STP on the Switch on page 572

• Displaying STP Settings on page 573

Using the Spanning Tree Protocol (STP) functionality of the switch makes your network more

fault tolerant. The following sections explain more about STP and the STP features supported by

XCM8800.

Note: STP is a part of the 802.1D bridge specification defined by the IEEE

Computer Society. To explain STP in terms used by the IEEE

802.1D specification, the switch will be referred to as a bridge.

XCM8800 supports the new edition of the IEEE 802.1D standard (known as IEEE 802.1D-2004)

for STP, which incorporates enhancements from the IEEE 802.1t-2001, IEEE 802.1W, and IEEE

802.1y standards. The IEEE 802.1D-2004 standard is backward compatible with the IEEE

802.1D-1998 standard. For more information, see

Compatibility Between IEEE 802.1D-1998 and

IEEE 802.1D-2004 STP Bridges on page 520.
