1-5Reflector ports and fabric ports do not support the flow-control no-pauseframe-sending command.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...

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 messages to the terminal, and remove the correspondingMAC forwarding entry.z If you have also enabled the loopback port auto-shutdown function on the port, the system will shutdown the port, and send log messages to the terminal. After the loop is removed, you need to usethe undo shutdown command to bring up the port.
