 After installing CentOS on to a server (software or appliance) you may have some IP ports that are incorrectly named. I have only seen this in CentOS v7.x and it mostly happens on SW only or appliance installs where the wrong CentOS .img file has been used (if you put the G7 CentOS7 build on a G6 for example).
