unconfigure mstp region


Unconfigures the MSTP region on the switch and returns all MSTP settings to their default values.

Syntax Description

This command has no arguments or variables.



Usage Guidelines

Before you unconfigure an MSTP region, we recommend that you disable all active STPDs in the region. This includes the CIST and any active MSTIs.

After you issue this command, all of the MSTP settings return to their default values, as described below:
  • Region Name—This indicates the name of the MSTP region. In the Extreme Networks implementation, the maximum length of the name is 32 characters and can be a combination of alphanumeric characters and underscores ( _ ).

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

  • Revision Level—This identifier is reserved for future use; however, the switch uses and displays a default of 3.


The following command unconfigures the MSTP region on the switch:
