Chapter 8. Network Interfaces 105• DNS{1,2}= address , where address is a name server address to be placed in/etc/resolv.conf if the PEERDNS directive is set to yes.• HWADDR= MAC-address , where MAC-address is the hardware address of the Ethernetdevice in the form AA:BB:CC:DD:EE:FF. This directive is useful for machines with multipleNICs to ensure that the interfaces are assigned the correct device names regardless of the configuredload order for each NIC’s module. This directive should not be used in conjunction with MACADDR.• IPADDR= address , where address is the IP address.• MACADDR= MAC-address , where MAC-address is the hardware address of the Ethernetdevice in the form AA:BB:CC:DD:EE:FF. This directive is used to assign a MAC address toan interface, overriding the one assigned to the physical NIC. This directive should not be used inconjunction with HWADDR.• MASTER= bond-interface ,where bond-interface is the channel bonding interface towhich the interface the Ethernet interface is linked.This directive is used in conjunction with the SLAVE directive.Refer to Section 8.2.3 Channel Bonding Interfaces for more about channel bonding interfaces.• NETMASK= mask , where mask is the netmask value.• NETWORK= address , where address is the network address. This directive is deprecated.• ONBOOT= answer , where answer is one of the following:• yes — This device should be activated at boot-time.• no — This device should not be activated at boot-time.• PEERDNS= answer , where answer is one of the following:• yes — Modify /etc/resolv.conf if the DNS directive is set. If using DHCP, then yes is thedefault.• no — Do not modify /etc/resolv.conf.• SLAVE= bond-interface ,where bond-interface is one of the following:• yes — This device is controlled by the channel bonding interface specified in the MASTER direc-tive.• no — This device is not controlled by the channel bonding interface specified in the MASTERdirective.This directive is used in conjunction with the MASTER directive.Refer to Section 8.2.3 Channel Bonding Interfaces for more about channel bond interfaces.• SRCADDR= address , where address is the specified source IP address for outgoing pack-ets.• USERCTL= answer , where answer is one of the following:• yes — Non-root users are allowed to control this device.• no — Non-root users are not allowed to control this device.
