Usage Guidelines

When a large number of broadcast packets are transmitted on a network, a lot of network resources are occupied, and services on the network are affected. You can run the broadcast-suppression command to enable broadcast traffic suppression in a BD and configure the maximum number of broadcast packets that can pass through a BD. When the broadcast traffic volume exceeds the specified threshold, the system discards excess broadcast packets.

Example

# Set the CIR value for broadcast traffic in BD 10 to 100 kbit/s.
