Usage Guidelines

Two switching devices belong to the same MST region only when they have the following same configurations:

• MST configuration name

• Mappings between MSTIs and VLANs

• MST region revision level

MSTP is a standard protocol, the MSTP revision level of a switching device is 0 by default. If the revision level of some devices from a specified manufacturer is not 0, you must change the MSTP revision level of devices to be the same to compatible with the spanning tree calculation in an MST region.

Example

• Set the MSTP revision level of the switching device to 5.
