13.1 Spa nning Tre e Pro to c o l O ve rvie w

The Switch supports Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP) and Multiple
Spanning Tree Protocol (MSTP) as defined in the following standards.

• IEEE 802.1D Spanning Tree Protocol

• IEEE 802.1w Rapid Spanning Tree Protocol

• IEEE 802.1s Multiple Spanning Tree Protocol

The Switch also allows you to set up multiple STP configurations (or trees). Ports can then be assigned to
the trees.

13.1.1 Wha t Yo u C a n Do

• Use the

Spa nning Tre e Pro to c o l

Sta tus

screen (

Section 13.2 on page 138

) to view the STP status in the

different STP modes (RSTP, MRSTP or MSTP) you can configure on the Switch.

• Use the

Spa nning Tre e C o nfig ura tio n

screen (

Section 13.3 on page 138

) to activate one of the STP

modes on the Switch.

• Use the

Ra pid Spa nning Tre e Pro to c o l

screen (

Section 13.4 on page 139

) to configure RSTP settings.

• Use the

Ra pid Spa nning Tre e Pro to c o l Sta tus

screen (

Section 13.5 on page 141

) to view the RSTP status

.

• Use the

Multiple Ra pid Spa nning Tre e Pro to c o l

screen (

Section 13.6 on page 142

) to configure MRSTP.

• Use the

Multiple Ra pid Spa nning Tre e Pro to c o l Sta tus

screen (

Section 13.7 on page 144

) to view the

MRSTP status.

• Use the

Multiple Spa nning Tre e Pro to c o l

screen (

Section 13.8 on page 146

) to configure MSTP.

• Use the

Multiple Spa nning Tre e Pro to c o l Sta tus

screen (

Section 13.9 on page 150

) to view the MSTP

status.

13.1.2 Wha t Yo u Ne e d to Kno w

Read on for concepts on STP that can help you configure the screens in this chapter.

(Ra pid) Spa nning Tre e Pro to c o l

(R)STP detects and breaks network loops and provides backup links between switches, bridges or
routers. It allows a switch to interact with other (R)STP -compliant switches in your network to ensure that
only one path exists between any two stations on the network.

The Switch uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allows faster convergence of the
spanning tree than STP (while also being backwards compatible with STP-only aware bridges). In RSTP,
topology change information is directly propagated throughout the network from the device that
