You must use either 802.1d or DEC to interconnect all bridges in a network using

All of Cabletron's bridge products have the ability to use either the 802.1d or DEC
Spanning Tree version, or they can be set so that no version is in effect. (A bridge
should be set to None if there are no redundant loops incorporated within the
