To answer this question using my use-case; I build HA clusters, and I want to make sure that physical port X on all nodes have the same device name. Biosdevname tries to address this, but doesn't work all the time. Further, in my case, I've got a minimum of six interfaces in each node, paired into three bonded groups. Having the device name reflect the purpose in the node is very helpful 12~24 months down the road when I need to fix a network problem. There *are* cogent arguments for renaming interfaces. cheers digimer On 05/10/14 04:17 PM, George Kontostanos wrote: > I really don't get it.
