Figure 6-11. Spanning Tree Protocol Window

The Spanning Tree Protocol window displays the following information:

Spanning Tree Version

The version shows the Spanning Tree Protocol type employed by this bridge:

IEEE 802.1d

DEC LAN 100

None

You must use either 802.1d or DEC to interconnect all bridges in a network using
parallel bridges. By default, a Cabletron bridge turns on the 802.1d Spanning Tree.
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
network.)
