Usage Guidelines

Usage Scenario

By default, if MAC address flapping detection is enabled on a device and MAC address flapping is detected, traffic suppression is triggered on the corresponding interface. As a result, excess traffic is discarded, resulting in packet loss.

To prevent this, disable unknown unicast traffic suppression.

Precautions

Unknown unicast traffic suppression takes effect on an interface only when the following conditions are met:

Global MAC address flapping detection is configured.
MAC address flapping occurs on the interface.
Unknown unicast traffic suppression is enabled globally.
Unknown unicast traffic suppression is enabled on the interface.

Example

# Disable unknown unicast traffic suppression on GE0/0/1.
