Configure storm control for unknown unicast packets received on the selected interface in Unicast control threshold.
- Upper threshold: specifies the upper rate limit in pps, byte, or percentage mode.
- Lower threshold: specifies the lower rate limit in pps, byte, or percentage mode.
Set the storm control action in Storm control action.
- None: indicates that no storm control action is configured.
