Usage Guidelines
•
Three MST region attributes (configuration name, revision level, and configuration digest) define an
MST region as required by the IEEE 802.1Q 2005 standard. Switches that share the same values for
these attributes are all considered part of the same region. Currently each switch can belong to one
MST region at a time.
•
This command is available when the switch is operating in either the 1x1 or flat Spanning Tree mode.
