Configure Spanning Tree Protocol
The Spanning Tree Protocol (STP) provides a tree topology for any arrangement of network
devices. STP also provides one path between end stations on a network, eliminating loops.
STP (also referred to as “classic” STP) provides a single path between end stations, avoiding
and eliminating loops. For information about configuring the gl
obal STP settings for the
switch, see
Configure the STP settings and view the STP status on page 179.
The switch support the following spanning tree versions:
• CST. Common STP. For information on configuring CST, see
Configure the CST settings
on page 181 and Configure the CST port settings on page 183.
• MSTP. Multiple Spanning Tree Protocol (MSTP
, also referred to as MST) supports
multiple instances of spanning tree to efficiently channel VLAN traffic over different
interfaces. For information on configuring MSTP, see
Manage the MST settings on
page 188 and Configure and view the port settings for an MST instance on page 191.
• RSTP. Rapid STP. Each instance of the spanning tree behaves in the manner specified in
IEEE 802.1w, Rapid Spanning
Tree (RSTP), with slight modifications in the working but
not the end effect (chief among the effects is the rapid transitioning of the port to the
forwarding state). For information on viewing the RSTP state, see
View the Rapid STP
information on page 187.
The difference between the RSTP and the traditional STP (IEEE 802.1D) is the ability to
configure and recognize full-duplex connectivity and ports that are connected to end
stations, resulting in rapid transitioning of the port to the forwarding state and the
suppression of
Topology Change Notification.
These features are represented by the
parameters pointtopoint and edgeport. MSTP is compatible with both RSTP and STP. It
behaves in a way that is appropriate for STP and RSTP bridges. An MSTP bridge can be
configured to behave entirely as an RSTP bridge or an STP bridge.
