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
global STP settings for the switch, see Configure the STP settings and display the STP
status on page 226.
The switch support the following spanning tree versions:
•
CST: Common STP. For information about configuring CST, see Configure the CST
settings and display the CST status on page 229 and Configure the CST interface
settings on page 231.
•
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 about configuring MSTP, see Manage MST instances on
page 236 and Configure and display the interface settings for an MST instance on
page 239.
•
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 (the main effect is the rapid transitioning of the port to the
forwarding state).
