Spanning Tree Protocol Configuration
Spanning Tree Protocol (STP) is a Layer 2 protocol that ensures a loop-free topology for any bridged
local area network (LAN). STP allows a network design to include spare (redundant) links to provide
automatic backup paths if an active link fails. STP creates a spanning tree within a mesh network
of connected Layer 2 bridges and disables those links that are not part of the tree, leaving a single
active path between any two network nodes.
The Management application supports the following types of STP:

STP or RSTP configuration on a port VLAN

You can configure STP and RSTP attributes from the VLAN View tab or the Product View tab.
1. Perform one of the following tasks to select the VLAN on which STP or RSTP will be configured:
2. Click the STP button on the VLAN Manager dialog box to display the STP Configuration dialog

STP—The Spanning tree protocol (IEEE 802.1d) is a link layer network protocol that ensures a
loop-free topology for any bridged LAN.
RSTP—Rapid Spanning Tree Protocol (IEEE 802.1w internet standard) is a refinement of STP,
which provides for faster spanning tree convergence after a topology change.
MSTP – Multiple Spanning Tree Protocol (IEEE 802.1s internet standard) allows several VLANs
to be mapped to a reduced number of spanning-tree instances. This is possible since most
networks do not need more than a few logical topologies. Each instance handles multiple
VLANs that have the same Layer 2 topology.
MSTP allows formation of MST regions that can run multiple MST instances (MSTI). Multiple
regions and other STP bridges are interconnected using one single Common Spanning Tree
(CST).
•
On the VLAN View tab, expand the list of VLANs and select one or multiple VLANs on which
STP, RSTP, or MSTP will be configured.
•
On the Product View tab, expand the product, product group, or IP subnet folder that
contains the products on which the VLAN you want is configured. Then expand the entry to
display its VLAN and select the VLAN where STP or RSTP will be configured. You can select
more than one VLAN from this tab
For either view, you can use the Search tool to look for the VLAN on which STP or RSTP will be
configured.
Either of these methods enables the STP button on the VLAN Manager dialog box.
box.
The products on which the VLAN is configured appear on the dialog box.
