I am running version 11.6. I found out how to change the hostname and make it stick. Once the hostname is changed then run the below commands. It will configure the BIGIP to not get its hostname from dhcp.

I have tried this several times on my AWS LTMs and it does not work. They always go back to the DHCP hostname. I am running 11.6.1. What happens is I change the hostname.
