Situation Resolution
The Ethernet driver works but the
transmit and receive data rates are
not near a 10 Gb/s line rate. There could be several reasons for poor performance. For best
performance practices, see “Network Performance Tuning” on
page 868.
ethtool configuration settings are not
restored after system reboot. The ethtool settings are not designed to persist across reboot.
For persistence, configuration commands should be invoked
from a boot script that is executed at system start such as
/etc/rc.local.
When MILI and SNMP daemons start,
they trigger warning messages within
SELinux for certain operations. This is a known issue and no solution is available. However, to
avoid SElinux warning messages, you can disable SELinux. To
disable SELinux, open a terminal and enter the following
command at the prompt:
echo 0 > /selinux/enforce
To enable SELinux, use the following command:
echo 1 > /selinux/enforce
