How to configure DHCP client options in RHEL7?

  • 772

I have a RedHat 7 server with a couple of network interfaces. One of those is DHCP enabled. 

DEVICE=eth4
BOOTPROTO=dhcp
ONBOOT=yes
USERCTL=no
IPV6INIT=no

My problem is that it can happen that the DHCP server for that network is not reachable at the time the server boots up. From my understanding, a retry time can be configured?! Is that correct in the first place?

From what I read so far this should be possible in the dhclient-conf (as described here or here).

However: I do not find any such config file on my RHEL7. I am not using NetworkManager (uninstalled it). Can anyone share some advice how to configure dhcp client options in RHEL7?

Thanks a lot!

    Well, I did not manage to get a dhclient.conf file configured. However, my actual goal, to get DHCP leases even after boot, this parameter in the ifcfg-eth4 did actually work:

    PERSISTENT_DHCLIENT=1

    Now the OS seems to keep checking for a DHCP server as long as it finds one.
