Hello, when booting using dhcp, some OS-es use their MAC addr, some, when getting an IP with DHCP use a client id, sometimes it's 01M+MAC, sometimes it is a quite long string, similar to UUIDs. For example some Ubuntu version sends out their DHCP client id as 01+MAC, similar to windows machines. Is there a way in Centos/RHEL, to 'configure' that? (Cisco equipment is kind of particlat about that), so that for example when requesting an IP using DHCP, the client-id used is 01+MAC instead of just the MAC address? (it becomes a hassle when machines are dual boot for example). thanks, Ron
