Hi Mikael,
I didn't do them in the .conf as its depreciated in Centos 6.
However I did move the miimon etc... lines to my network scripts file and still no dice.
I didn't try your suggestions as it looks too much like a patch, not very clean like it used to be in version 5.
So I basically had done what you suggested but w/o the arp lines.
I'm in no hurry for this although I will keep your suggestions in my notes as I may have an up coming Centos 6 server that absolutely needs binding.
Thanks for the reply.
