Errors with ifup regarding MAC addresses

Posted by: major in Command Line

If Redhat, CentOS, Fedora, or any other similar OS provides the following error:
# ifup eth1
Device eth1 has different MAC address than expected, ignoring.

Check that someone didn’t put an IP in as a hardware address:
DEVICE=eth1
HWADDR=10.240.11.100
NETMASK=255.255.224.0
ONBOOT=yes
TYPE=Ethernet

If they did, then fix it with the correct configuration directive:
DEVICE=eth1
IPADDR=10.240.11.100
NETMASK=255.255.224.0
ONBOOT=yes
TYPE=Ethernet
