undo multicast-suppression

Parameters

Parameter	Description	Value

Usage Guidelines

When the traffic rate of unknown multicast packets exceeds the maximum value, the system discards excess unknown multicast packets to control the traffic rate and ensure normal operation of network services.

Example

# Set the maximum percentage of unknown multicast traffic to 20% of interface bandwidth on Eth-Trunk1.
