The storm-constrain, broadcast-suppression, multicast-suppression, and unicast-suppression commands can suppress storms on an interface. When the broadcast traffic on the interface exceeds this threshold, the system drops packets until the traffic drops below this threshold. By default, Ethernet interfaces do not suppress broadcast traffic. This chapter describes how to configure management Ethernet interfaces and Ethernet. The functions of Comware 9 network devices are categorized into the management plane, control plane, and data plane. Use undo bandwidth to restore the default.
