Usage Guidelines

Usage Scenario

To ensure that only one switch becomes the master switch after a stack splits, thereby enhancing stack stability, run the mad detect mode direct command to configure MAD in direct mode on an interface.

Configuration Impact

Configuring MAD in direct mode on an interface blocks the interface. Disabling MAD in direct mode on an interface restores the forwarding function of the interface. If a loop exists on the network, a broadcast storm occurs.

Precautions

The undo mad detect command is not supported in the port group view. You can only run the undo mad detect mode direct command in the port group view to disable MAD in direct mode.

Example

# Configure MAD in direct mode on GigabitEthernet0/0/1.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] 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
