What’s the MSTP Configuration on region-name

MSTP Configuration

Function Description

The multiple spanning tree protocol (MSTP) applies to the redundant network. MSTP is an improvement of STP and RSTP. MSTP prevents the proliferation and infinite cycling of the packets in the loop network. In addition, MSTP provides multiple redundant paths for VLAN data transmission to achieve the load-sharing purpose. The MA5680T/MA5683T/MA5608T supports MSTP, which is compatible with the STP and RSTP. It supports MSTP loop network that helps meet various networking requirements.

region-name

Function

The region-name command is used to set the region name of multiple spanning tree (MST) which bridges belong to. The MST region name is used to identify the MST region. Devices with different names are in different MST regions. After the MST region name is set, two devices with the same MST region name may be in the same MST region.

The undo region-name command is used to restore the default region name of MST. When users need to identify the MST region by using the default name or query the default MST region name, run this command. After that, the MST region name is in the hexadecimal form of device MAC address.

Format

region-name name

undo region-name

Parameters

Parameter Description Value
name Indicates the MST region name of the bridge. Character string type, a string of 1-32 case sensitive characters that consists of letters, digits, hyphens (-), and underscores (_).

Default: the hexadecimal form of device MAC address.

Modes

MST region mode

Level

Operator level

Usage Guidelines

  • Run the config command to enter global config mode, and then run the stp region-configuration command to enter MST region mode.
  • Two devices that belong to a same MST region meet the following requirements:
    • The region names are the same.
    • The revision levels are the same.
    • The configuration digests are the same. The configuration digest is calculated by VLAN mapping table of all the spanning trees and MD5-KEY through MD5 encryption algorithm.

Example

To set MST region name of the bridge as huawei-bridge, do as follows:

huawei(stp-region-configuration)#region-name 
{ string<S><Length 1-32> }:huawei-bridge

  Command:
          region-name huawei-bridge

To restore the default MST region name, do as follows:

huawei(stp-region-configuration)#undo region-name 

System Response

  • The system does not display any message after the command is executed successfully.
