The value ranges from 1 to 100 and defaults to 100. The smaller the ratiois, the less broadcast traffic is allowed.bandwidth bandwidth: Specifies the maximum bandwidth of broadcast traffic receivedon the Ethernet port. For a 100 Mbps port, the bandwidth argument is in the range of 1to 100 in Mbps; for a gigabit port, the bandwidth argument is in the range of 1 to 1000 inMbps.pps pps: Specifies the maximum number of broadcast packets allowed to be receivedper second on an Ethernet port (in pps).z For a 100 Mbps Ethernet port, the pps argument is in the range of 0 to 148,810.z For a Gigabit Ethernet port, the pps argument is in the range of 1,488,100.z For a 10GE port, the pps argument is in the range of 0 to 14,881,000.DescriptionUse the broadcast-suppression command to limit broadcast traffic allowed to bereceived on each port (in system view) or on a specified port (in Ethernet port view).Use the undo broadcast-suppression command to restore the default broadcastsuppression setting.When incoming broadcast traffic exceeds the broadcast traffic threshold you set, thesystem drops the packets exceeding the threshold to reduce the broadcast traffic ratioto the reasonable range, so as to keep normal network service.By default, broadcast suppression is disabled.
