Alternatively, you can use NCLU commands. To administratively bring the interface up or down for example, to bring down a port, bridge, or bond but not the physical connection for a port, bridge, or bond, you can use the -admin-state option. When you bring down the physical connection to an interface, it is brought back up automatically after any future reboots or configuration changes with ifreload -a. The ifdown command always deletes logical interfaces after bringing them down. The following example command brings down the physical connection to swp1: sudo ifdown swp1 To bring down the physical connection to a single interface, run the sudo ifdown command. The following example command brings up the physical connection to swp1: sudo ifup swp1 To bring up the physical connection to an interface or apply changes to an existing interface, run the sudo ifup command. Use the verbose option ( -v) to show commands as they are executed when bringing an interface down or up.
