1-4Enabling Flow Control on a PortFlow control is enabled on both the local and peer switches. If congestion occurs on the local switch:z The local switch sends a message to notify the peer switch of stopping sending packets to itself orreducing the sending rate temporarily.z The peer switch will stop sending packets to the local switch or reduce the sending rate temporarilywhen it receives the message; and vice versa. By this way, packet loss is avoided and the networkservice operates normally.Follow these steps to enable flow control on a port:To do... Use the command... RemarksEnter system view system-view —Enter Ethernet port view interface interface-typeinterface-number —Enable flow control on theEthernet port flow-control By default, flow control is notenabled on the port.Duplicating the Configuration of a Port to Other PortsTo make other ports have the same configuration as that of a specific port, you can duplicate theconfiguration of a port to specific ports.Specifically, the following types of port configuration can be duplicated from one port to other ports:VLAN configuration, protocol-based VLAN configuration, LACP configuration, QoS configuration,GARP configuration, STP configuration and initial port configuration. Refer to the command manual forthe configurations that can be duplicated.Follow these steps to duplicate the configuration of a port to specific ports:To do... Use the command... RemarksEnter system view system-view —Duplicate theconfiguration of a port tospecific portscopy configuration source { interface-typeinterface-number | aggregation-groupsource-agg-id } destination { interface-list[ aggregation-group destination-agg-id ] |aggregation-group destination-agg-id }Requiredz If you specify a source aggregation group ID, the system will use the port with the smallest portnumber in the aggregation group as the source.z If you specify a destination aggregation group ID, the configuration of the source port will be copiedto all ports in the aggregation group and all ports in the group will have the same configuration asthat of the source port.
