The set protocols spanning-tree mstp revision-level command sets the revision level of the MST region.
set protocols spanning-tree mstp revision-level <level>
Specifies the revision level of the MST region. The value is an integer that ranges from 0 to 65535. The default value is 0.
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.
- Set the MSTP revision level of the switching device to 5.
