# If USE_DHCP[interface] is set to "yes", this overrides any other settings.
# If you don't have an interface, leave the settings null ("").
#
# You can configure network interfaces other than eth0,eth1... by setting

# Example of how to configure a bond (link aggrigation) interface.
# Note the addition of the BONDNICS and BONDMODE parameters.
# BONDNICS is a space delimited list of interfaces to add to this bond. The
# BONDNICS interfaces will be brought up and configured while bringing up the
# bond interface, so do not need to be previously defined in rc.inet1.conf.
# BONDMODE sets the bonding mode for this interface. If not specified when
# BONDNICS has been used, the default is 'balance-rr'.
# IFOPTS is a pipe (|) delimited list of bonding module specific settings to be
# applied to the interface, and should always include the 'miimon' option when
# configuring bonding - not using this option will result in network
# degradation. In 'active-backup' mode, the 'primary' option should also be
# supplied. When using '802.3ad' mode, set "lacp_rate fast" for faster
# recovery from an interface failure. In other modes, the 'xmit_hash_policy'
# should be set. See the /usr/src/linux/Documentation/networking/bonding.txt
# file (search for "Bonding Driver Options") for the full set of options.
