Understanding the Naming Scheme
The network interfaces are named based on their location on the system board.
The naming scheme implemented is
Lan On Motherboard (LOM) interfaces:
em<port number>_<virtual function instance>
PCI add-in interfaces:
p<slot number>p<port number>_<virtual function instance>
The naming scheme is enabled by default on supported PowerEdge systems. The
naming scheme can be disabled by passing the biosdevname=0 kernel
command line parameter during the installation. If a system is upgraded from
Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 6 SP1, the network
interface names present in Red Hat Enterprise Linux 6 are preserved across the
upgrade.
