is the hardware address of the Ethernet device in the form AA:BB:CC:DD:EE:FF. This directive is useful for machines with multiple NICs to ensure that the interfaces are assigned to the correct device names regardless of the configured load order for each NIC's module, This directive should not be used in conjunction with MACADDR. Note: Red Hat does not support assigning a permanent MAC address to bond interfaces in active-backup mode with the fail_over_mac option set to follow or active.Īfter performing the necessary changes in the network configuration files make sure to reboot the system for the MAC address to take effect. # cat /etc/sysconfig/network-scripts/ifcfg-bond0īONDING_OPTS="mode=active-backup primary=eno1 miimon=100" # cat /etc/sysconfig/network-scripts/ifcfg-eno2 # cat /etc/sysconfig/network-scripts/ifcfg-eno1

Forcing a bond to get its MAC address from a specific slave, MACADDR directive has to be added with the MAC address of the required slave to /etc/sysconfig/network-scripts/ifcfg-bondX file.The HWADDR directive is changed with MACADDR : # cat /etc/sysconfig/network-scripts/ifcfg-eth1Īssigning permanent MAC address for a bonding network interface. # cat /etc/sysconfig/network-scripts/ifcfg-eth1 If HWADDR= directive is present in the network configuration file then make sure to replace it with MACADDR= directive and its corresponding value as follows: So that this value will be taken as the permanent MAC address of the network interface.
