Function

The mac-address flapping mac-syn-suppress disable command disables real-time MAC address synchronization suppression triggered by MAC address flapping.

The undo mac-address flapping mac-syn-suppress disable command enables real-time MAC address synchronization suppression triggered by MAC address flapping.

By default, MAC address synchronization suppression triggered by MAC address flapping is enabled.

Usage Guidelines

By default, real-time MAC address synchronization suppression is enabled on a device. With this function enabled, if a large number of real-time MAC address synchronization packets are generated due to persistent MAC address flapping, real-time MAC address synchronization suppression will be triggered. This will result in problems such as delay in obtaining DHCP addresses in terminal roaming scenarios. To address such problems, run the mac-address flapping mac-syn-suppress disable command to disable real-time MAC address synchronization suppression triggered by MAC address flapping.
