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).

In your ifcfg file set:

DHCP_CLIENT_ID=

to whatever you want. I don't know of a way to automatically use the 01+MAC scheme.
