How to set AUTONEG OFF on RedHat WS 4 update 5
We run Redhat Workstation 4 update 5 (64-bit) and tried to set the autoneg off using the following command and received errors:
#ethtool -s ethx autoneg off speed 1000 duplex full
Cannot set new settings: Invalid argument
not setting speed
not setting duplex
not setting autoneg
editted the file /etc/sysconfig/network-scripts/ifcfg-ethx to include the following line:
ETHTOOL_OPTS="autoneg off speed 1000 duplex full"
and run the command: #service network restart
This action disabled the interface. We have rebooted and the interface is still disabled. We have chenged the ifcfg-ethx file back to the original form and rebooted, still the same problem.
Please help out with some advise.
