6–Configuring NIC Functionality in the Converged Network Adapter
Configuring the NIC in a Linux Environment

Loading the Bonding Driver
In most RHEL 5 environments, the bonding driver is not loaded by default. Unless
the bonding driver is loaded, bond interfaces using the QLogic adapter NIC
function cannot be created.
To determine whether the bonding driver is loaded, enter the following command:
# lsmod | grep bonding
If the command produces no output, the bonding driver is not loaded. If the output
is similar to Figure 6-31, the bonding driver is already loaded.
Figure 6-31. Verifying that the Bonding Driver Is Loaded
To load the bonding driver, enter one of the following commands:
# modprobe -v bonding miimon = x
or
# modprobe -v bonding arp_interval=n arp_ip_target=yy.yy.yy.yy
use_carrier Specifies MII/ETHTOOL ioctls
or netif_carrier_ok() for use by
miimon to determine the link
status. MII/ETHTOOL ioctls is
less efficient and uses a dep-
recated calling sequence
within the kernel. The
netif_carrier_ok() relies on the
device driver to maintain its
state with netif_carrier_on/off.
1 1–enables the use of
netif_carrier_ok()
0–enables use of MII/
ETHTOOL ioctls
