Udev handles the association between various devices and the network node name they get assigned.

OpenSUSE configures these devices via YaST, and the naming relates to the corresponding device's MAC address AFAIU. While the hardware ships with default MAC addresses, Virtual Connect can assign MAC addresses that override the factory default MAC addresses while the server remains in that Virtual Connect enclosure. The network config files are usually ifcfg-eth files. The MAC address is a 48-bit number that uniquely identifies the Ethernet interface to other devices on the network. See page 64 of the Virtual Connect Installation Guide for an explanation of the feature:Įach server blade Ethernet NIC ships with a factory default MAC address. There are options to manage the server MAC addresses using Virtual Connect. If you do have Virtual Connect modules, check the server profile in the Virtual Connect Manager.

This will cause the network service to update /etc/nf with the specified DNS servers specified. where MAC-address is the hardware address of the Ethernet device in the form. where ip-address is the address of a DNS server. For example, the ifcfg-eth0 file for an interface using DHCP looks. Since you mention that this is a blade server, do you know if the blade chassis has HP Virtual Connect modules installed? These are often used instead of passthrough ethernet uplinks to help consolidate and virtualize the blade networking. To configure an interface to use particular DNS servers, add the following lines to the ifcfg file: PEERDNS no DNS1ip-address DNS2ip-address. This is something that may be unique to the HP blade chassis setup. So it seems likely that something on the system is telling CentOS that the MAC should be used but I'm not sure where. Important In Red Hat Enterprise Linux 7, the naming convention for network interfaces has been changed, as explained in Chapter 11, Consistent Network Device Naming. I've also completely reinstalled CentOS and the problem persists. For more IPv6 ifcfg configuration options, see nm-settings-ifcfg-rh (5) man page. Note that none of them pertain to the MAC that CentOS thinks should be there. When I check the port mapping for the device bay that belongs to the server, I see: Mezzanine Device Port: ENET1 I'm not sure where the 18:a9 MAC addresses are coming from.

On the CenTOS host, I'm seeing this in ifconfig results (slightly modified to protect the innocent): eth0 HW 18:a9:05:71:xx:xc Where can I definitively confirm what the system sees at the MAC address? ifconfig -a shows the 'incorrect' one. In fact, if I use the MAC address that shows up in the onboard administrator and try to hardcode it to the nic (under /etc/sysconfig/network-script/ifcfg-eth0), I get an error:ĭevice eth0 has different MAC address than expected. modify the mac address in/etc/sysconfig/network-scripts/ifcfg-eth0. For some reason CentOS thinks the mac address for ETH0 is something (18:a9:05:71:xx:xc) but I'm not able to find that MAC at all on the on-board administrator. Vmware clone centos modify linux mac address Device eth0 does not seem to be. It does not store any personal data.I've got a HP Proliant 460c blade server running CentOS 5.x.
