Network
NOTE: To update your system with the latest operating system packages using RHN (Red Hat Network) service, see
www.rhn.redhat.com.
Red Hat periodically releases software updates to x issues, address security issues, and add new features and hardware support. You can
download updated operating system packages and the latest kernel releases and updates:
• By performing a manual download from the RHN service at www.rhn.redhat.com.

It is recommended that you use the RHN service to update your system software to the latest revisions before you deploy your system.
Important information
biosdevname utility
In the earlier versions of Red Hat Enterprise Linux, the interface names that are assigned by the operating system did not map to the
corresponding ports on the system board or on the add-in network adapters. For example, eth0 need not necessarily be associated with
port0 on the system board.
Red Hat Enterprise Linux 6.1 supports the biosdevname utility. The biosdevname utility enables the operating system to logically assign
and map Ethernet interface names with the respective physical ports on the system board or the add-in network adapters.
The new naming convention is as follows:
Lan-On-
Motherboard
interfaces
em <port number>
(ethernet-on-motherboard <1,2,..>)
PCI add-in interfaces p<slot number>p<port number>_<virtual function instance>
For more information on the biosdevname utility and the new naming scheme, see www.linux.dell.com/les/whitepapers.
NOTE
: Npar capability has been provided in Red Hat Enterprise Linux 6.2.
NOTE: If you do not wish to use the new naming scheme, you can turn if o during installation or post installation by passing the
kernel command line parameter biosdevname=0. The new naming scheme is enforced by default at the time of installation and
run time on supported Dell EMC systems.
