If congestion occurs on thelocal switch:z The local switch sends a message to notify the peer switch of stopping sendingpackets to itself or reducing the sending rate temporarily.z The peer switch will stop sending packets to the local switch or reduce the sendingrate temporarily when it receives the message; and vice versa. By this way, packetloss is avoided and the network service operates normally.Table 1-3 Enable flow control on a portOperation 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 isnot enabled on the port.1.1.4 Duplicating the Configuration of a Port to Other PortsTo make other ports have the same configuration as that of a specific port, you canduplicate the configuration of a port to specific ports.Specifically, the following types of port configuration can be duplicated from one port toother ports: VLAN configuration, protocol-based VLAN configuration, LACPconfiguration, QoS configuration, GARP configuration, STP configuration and initialport configuration.
