In order to prevent communication problems, it is necessary to update the
changed MAC address stored in the related ifcfg-eth<x> definition file.
To update the MAC address, proceed as follows:
I
Procedures may differ depending on your Linux OS or the definition file
on the client system. Use the following information as reference. Ask the
system administrator to change the definition file.
Ê After replacing a network controller or the system board, switch on and boot

following command:
# vi /etc/sysconfig/network-scripts/ifcfg-eth1
In vi, specify the new MAC address as follows:
HWADDR=xx:xx:xx:xx:xx:xx
Ê Save and close the definition file.
Ê For the changes to take effect, you need to reboot the network by entering
the following command:
# service network restart
I
If the system board or network controller offers multiple LAN ports, it is
necessary to update the remaining ifcfg-eth<x> definition files accordingly.
Ê Update the NIC configuration file to reflect the new card sequence and MAC
address.
