Centos 6 or 7 no DHCP IP during startup on first boot or reboot solution

This is usually because of STP causing a delay in the negotiation.

Edit your ifcfg script eg:

/etc/sysconfig/network-scripts/ifcfg-eth0

Add a LINKDELAY of 30 seconds or whatever works for you:

LINKDELAY=30
 

After that you should have an IP during bootup.
