Networking Requirements

As shown in Figure 8-34, SwitchA and SwitchB set up a CSS.

MAD can be used to detect dual master switches with the same configuration on the network to reduce the impact of a CSS split on the network.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Configure MAD in direct mode on a specified port.

Procedure

  1. Configure MAD in direct mode on a specified port.

    # Configure MAD in direct mode on GigabitEthernet1/1/0/5.

    <HUAWEI> system-view
    [HUAWEI] interface gigabitethernet 1/2/0/0
    [HUAWEI-GigabitEthernet1/2/0/0] mad detect mode direct
    Warning: This command will block the port, and no other configuration running on
     this  port is recommended. Continue?[Y/N]:y
    [HUAWEI-GigabitEthernet1/2/0/0] quit

    # Configure MAD in direct mode on GigabitEthernet2/1/0/5.

    [HUAWEI] interface gigabitethernet 2/10/0/0
    [HUAWEI-GigabitEthernet2/10/0/0] mad detect mode direct
    Warning: This command will block the port, and no other configuration running on
     this  port is recommended. Continue?[Y/N]:y
    [HUAWEI-GigabitEthernet2/10/0/0] quit
    [HUAWEI] quit

  2. Verify the configuration.

    # Check detailed MAD configuration of the CSS.
