Tried to run reapply (via DBus call, but also tried nmcli), have 
"NetworkManager[916]: <info>  [1545650569.2423] audit: op="device-reapply" interface="eth4" ifindex=2 
pid=28554 uid=0 result="success" "
in syslog, but no DHCP activity observed on the link.

What I'm doing wrong here?

For the record it's Ubuntu 16.04 LTS with nm version 1.2.6

Thanks
