How to change the eth0 interface settings on MMS?

By default on MMS the interface eth0 is set to do auto-negotiation with the switch it connects to. 

However, in case the layer 2 switch has the MMS port nailed with no auto-negotiation, the MMS port should be nailed in the same manner. 

For example, if the L2 switch is set to 100 Full with no autoneg, we could set the MMS eth0 interface as follows: 
     
#ethtool –s eth0 speed 100 duplex full autoneg off 

In order to make the change permanent, we should edit the file ifcfg-eth0 located in: 

/etc/sysconfig/network-scripts, to include the following line: 
     ETHTOOL_OPTS=”speed 100 duplex full autoneg off”
