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 282 and Configure the CST interface
settings
on page 284.

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 289 and Configure and display the interface settings for an MST instance on
page 292.

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).

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 messages. These features are
represented by the ‘pointtopoint’ and ‘edgeport’ parameters. 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.

PVST: Per-VLAN Spanning Tree (PVST) provides a unique instance of spanning tree
for each VLAN. For information about configuring PVTP, see Configure the
PVST/RPVST VLAN settings
on page 296 and Configure the PVST and RPVST interface
settings
on page 299.

RPVST: Rapid Per-VLAN Spanning Tree (RPVST) provides a unique instance of
spanning tree for each VLAN with each instance behaving in the manner specified
in IEEE 802.1w, Rapid Spanning Tree (RSTP). Compared to PVST, RPVST provides a
faster spanning tree convergence in response to Layer 2 topology changes.

For information about configuring RPVTP, see Configure the PVST/RPVST VLAN
settings
on page 296 and Configure the PVST and RPVST interface settings on page
299.

NOTE: For two bridges to be in the same region, the force version must be
802.1s and their configuration names, digest keys, and revision levels must
match. For additional information about regions and their effect on network
topology, refer to the IEEE 802.1Q standard.
