To start this procedure, execute the "ifconfig" command on the interface that will be getting assigned an IP address over DHCP and verify that IP address has not been assigned.
ifconfig ens9f1
Next, execute the following command to obtain an IP address from ONOS.
dhclient ens9f1
Note: When the dhclient command completes a common error message is displayed as follows. This mesage can safely be ignored.
mv: cannot move '/etc/resolv.conf.dhclient-new*' to '/etc/resolve.conf'
Then verify that an IP address was dynamically assigned to your interface
ifconfig ens9f1
