Usage Guidelines

Although this command is displayed in the CLI, it is reserved for future use. Please do not use this command.

If you accidentally configure this command, remember that each switch in the region must have the same MSTP configuration attributes, also known as MSTP region identifiers. These identifiers consist of the following:
  • Region Name—The name of the MSTP region.

  • Format Selector—The number used to identify the format of MSTP BPDUs. The default is 0.

  • Revision Level—An unsigned integer encoded within a fixed field of 2 octets that identifies the revision of the current MST configuration. MSTP revision level can be set from 0 to 65536, with the default being 3. The revision number is not incremented automatically each time that the MST configuration is committed.


The following command returns the MSTP revision number to 3, the default revision number:

configure mstp revision 3
