For the detailed copy content,please refer to the Command Manual.Table 1-4 Duplicate the configuration of a port to specific portsOperation Command RemarksEnter system view system-view —Duplicate theconfiguration of aport to specific portscopy configuration source { interface-type interface-number |aggregation-group source-agg-id } destination { interface-list[ aggregation-group destination-agg-id ] | aggregation-groupdestination-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.Configure loopback detection for Ethernet port(s)Loopback detection is used to monitor if a port of a switch is looped back.After you enable loopback detection on Ethernet ports, the switch can monitor if an external loopbackoccurs on them. If there is a loopback port found, the switch will deal with the loopback port according toyour configuration.1) If a loop is found on an access port, the system will set the port to the block state (ports in this statecannot forward data packets), send log and trap messages to the terminal, and remove thecorresponding MAC forwarding entry.
