However, it is also possible to edit the configuration files for a given network interface manually.
Below is a listing of the configurable parameters in an Ethernet interface configuration file:
•
BOOTPROTO=<protocol>
• — No boot-time protocol should be used.
none
• — The BOOTP protocol should be used.
bootp
• — The DHCP protocol should be used.
dhcp
•
BROADCAST=<address>
deprecated, as the value is calculated automatically with
• , where
DEVICE=<name>
dynamically-allocated PPP devices where it is the logical name).
• — Only use this option if the DHCP server requires the client to specify a
DHCP_HOSTNAME
hostname before receiving an IP address. (The DHCP server daemon in Red Hat Enterprise
Linux does not support this feature.)
•
DNS{1,2}=<address>
/etc/resolv.conf
•
ETHTOOL_OPTS=<options>
. For example, if you wanted to force 100Mb, full duplex:
ethtool
ETHTOOL_OPTS="autoneg off speed 100 duplex full"
Note that changing speed or duplex settings almost always requires disabling autonegotiation
with the
autoneg off
dependent.
•
GATEWAY=<address>
device (if any).
•
HWADDR=<MAC-address>
device in the form

configured load order for each NIC's module. This directive should not be used in conjunction
