Linux Enumeration of NICs
Linux operating system versions that use the udev kernel device manager enumerate the NICs differently
than earlier Linux versions that used the devfs device manager. Although this does not affect system
functionality, when using Red Hat
operating systems, the NICs are enumerated in reverse: NIC1 is configured as eth1 rather than as eth0,
and NIC2 is configured as eth0 instead of eth1. For further information on how to change the default
device enumerations, see the "Network Interface Card Naming" white paper available at linux.dell.com.
