Feature Summary
Feature Descriptions
802.1s Multiple Spanning Tree
The Alcatel Spanning Tree implementation provides support for the IEEE 802.1s Multiple Spanning Tree
Protocol (MSTP), 802.1W Rapid Spanning Tree Algorithm and Protocol (RSTP), and the 802.1D Span-
ning Tree Algorithm and Protocol (STP). All three supported protocols ensure that there is always only
one data path between any two switches for a given Spanning Tree instance to prevent network loops.
802.1s MSTP is based on 2003 802.1Q standard. MSTP allows the configuration of Multiple Spanning
Tree Instances (MSTIs) in addition to the CST instance. Each MSTI is mapped to a set of VLANs. As a
result, flat mode can now support the forwarding of VLAN traffic over separate data paths.
