The appliance is generating millions of CRC and input errors.
Interface is configured as half duplex
Diagnosing The Problem
Run the command:
Where N is the ethernet interface associated with the appliance IP.
Check if the ethernet interface is running half duplex.
Resolving The Problem
Before you begin:
- It is recommended to run these commands through the IMM or DRAC console as you may loose connectivity to the machine for a few minutes while speeds are reset.
- The issue may be a switch speed setting is not on Auto Negotiating. You may also want to hard set the switch to 1000 Mb/s Full Duplex. If this is the case contact your network administrator.
Force the speed of the interface using the "
ETHTOOL_OPTS" setting in the file /etc/sysconfig/network-scripts/ifcfg-eth
Append the line as follows to disable Auto-Negotiation, enable Full Duplex and set up Speed to 1000 Mb/s :
ETHTOOL_OPTS="autoneg off duplex full speed 1000"
