Unable to activate eth1 - device eth1 has different MAC address than expected.
Hi all, I have a red hat linux server with 2 network interfaces. Lately I'm trying to activate the 2nd network interface (eth1) but I encountered following errors: -
#service network status Configured devices: lo eth0 eth1 Currently active devices: lo eth0 #ifup eth1 Device eth1 has different MAC address than expected, ignoring. # cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none HWADDR=00:17:08:5D:6E:66 ONBOOT=no TYPE=Ethernet IPADDR=168.232.90.174 NETMASK=255.255.255.0 USERCTL=no PEERDNS=no IPV6INIT=no Appreciate if anyone can help me to resolve this? Following are some other output from the server: - # lsmod Module Size Used by 8021q 23249 0 sg 42489 0 cpqci 41576 3 mptctl 73736 0 parport_pc 29185 0 lp 15089 0 parport 43981 2 parport_pc,lp lpfcdfc 197716 6 autofs4 23241 0 i2c_dev 13633 0 i2c_core 28481 1 i2c_dev sunrpc 170425 1 ds 21449 0 yenta_socket 22977 0 pcmcia_core 69329 2 ds,yenta_socket dm_mirror 28889 0 dm_multipath 22097 0 dm_mod 66433 2 dm_mirror,dm_multipath button 9057 0 battery 11209 0 ac 6729 0 md5 5697 1 ipv6 282657 22 uhci_hcd 34665 0 ehci_hcd 33349 0 hw_random 7137 0 tg3 133124 0 ext3 137681 3 jbd 68849 1 ext3 mptspi 12556 0 mptsas 23960 0 mptscsih 44944 2 mptspi,mptsas qla2xxx 1012256 0 qla2xxx_conf 303240 1 lpfc 203524 1 lpfcdfc scsi_transport_fc 11201 2 lpfcdfc,lpfc cciss 75848 7 sd_mod 19393 0 scsi_mod 140177 10 sg,lpfcdfc,mptspi,mptsas,mptscsih,qla2xxx,lpfc,scsi_transport_fc,cciss,sd_mod mptbase 70560 4 mptctl,mptspi,mptsas,mptscsih # more /etc/modprobe.conf alias eth0 tg3 alias eth1 tg3 alias scsi_hostadapter cciss alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd alias scsi_hostadapter1 lpfc options lpfc lpfc_nodev_tmo=30 lpfc_lun_queue_depth=16 lpfc_discovery_threads=32 alias scsi_hostadapter2 qla2xxx_conf alias scsi_hostadapter3 qla2xxx options qla2xxx ql2xmaxqdepth=16 qlport_down_retry=30 ql2xloginretrycount=30 ql2xfailover=1 ql2xlbType=1 ql2xautorestore=0xa0 ConfigRequire d=0 remove qla2xxx /sbin/modprobe -r --first-time --ignore-remove qla2xxx && { /sbin/modprobe -r --ignore-remove qla2xxx_conf; } #Added by HP rpm installer alias scsi_hostadapter_mptbase_module mptbase #Added by HP rpm installer alias scsi_hostadapter_mptscsih_module mptscsih #Added by HP rpm installer alias scsi_hostadapter_mptspi_module mptspi #Added by HP rpm installer alias scsi_hostadapter_mptsas_module mptsas # lspci -vv|grep -i eth pcilib: Resource 0 in /sys/bus/pci/devices/0000:03:01.1/resource has a 64-bit address, ignoring pcilib: Resource 5 in /sys/bus/pci/devices/0000:00:1f.1/resource has a 64-bit address, ignoring 03:01.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10) 03:01.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10) |
Try
ifconfig -a to show the actual MAC address, and change the ifcfg-ethx to suit.. |
Hi Fukawi1, thank you for the advise, but the thing is this interface is not even appear in the ifconfig -a output, so there's no way to get the hardware address from it.
I actually tried restart the network service to see whether I can get the hardware address but still feel with following error: - # service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Setting network parameters: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] Bringing up interface eth1: tg3 device eth1 does not seem to be present, delaying initialization. [FAILED] From lspci output, I guess the "03:01.1" refer to this interface (eth1): - # lspci|grep Ethernet pcilib: Resource 0 in /sys/bus/pci/devices/0000:03:01.1/resource has a 64-bit address, ignoring pcilib: Resource 5 in /sys/bus/pci/devices/0000:00:1f.1/resource has a 64-bit address, ignoring 03:01.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10) 03:01.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10) From the dmesg output there seems to have errors on this "03:01.1", is this because it has driver issue?? # dmesg|grep 03:01.1 ACPI: PCI interrupt 0000:03:01.1[B] -> GSI 25 (level, low) -> IRQ 209 PCI: Failed to allocate mem resource #0:10000@120000000 for 0000:03:01.1 PCI: Enabling device 0000:03:01.1 (0140 -> 0142) ACPI: PCI interrupt 0000:03:01.1[B] -> GSI 25 (level, low) -> IRQ 209 PCI: Unable to reserve mem region #1:ffffffffdde00000@120000000 for device 0000:03:01.1 |
So you have two physical network cards i.e. eth0 and eth1 on the same machine
can you post the output of these files Code:
#vi /etc/sysconfig/network-scripts/ifcfg-eth0 |
deep27ak, I could be wrong, but i dont believe it is possible for two nics to have the same MAC, that kinda defeats the point of a unique identifies.
wkk1020, i looked up your card, and saw its a dual port card, in my experience, a dual onboard, or dual pci ethernet card, the MAC's have always been the same except for the last bit, being higher or lower by one. as an example, my gateway is a HP DL380G2, with dual onboard nics, plus a PCI card with DUAL nics, the MAC address' are as follows: Code:
gateway ~/scripts # ifconfig | grep "eth" But it sounds to me like the system isnt recognising both adapters. Perhaps its a driver related problem, maybe the linux drivers are only capable of recognising that chipset as a single interface? |
Oh I am sorry I guess U r rite ILL just edit my post before I confuse anyone else

Hi deep27pak, please see following for the outputs, for your information, eth0 is all along up and running.
eth1 previously was not activated and not connected to the network, lately we're trying to activate eth1 and encountered the mentioned issue. The original ifcfg-eth1 file has "HWADDR=00:17:08:5D:6E:66" but when I tried to ifup it I encountered "Device eth1 has different MAC address than expected, ignoring.", but even remove the "HWADDR" from ifcfg-eth1 also didn't help: - # cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none BROADCAST=168.232.220.255 HWADDR=00:22:64:2d:ad:37 IPADDR=168.232.220.76 NETMASK=255.255.255.0 NETWORK=168.232.220.0 ONBOOT=yes TYPE=Ethernet USERCTL=no PEERDNS=yes GATEWAY=168.232.220.1 IPV6INIT=no # cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes TYPE=Ethernet IPADDR=168.232.90.174 NETMASK=255.255.255.0 USERCTL=no PEERDNS=no IPV6INIT=no |
Hi fukawi1, this is the HWaddr for the up and running eth0
# ifconfig|grep eth eth0 Link encap:Ethernet HWaddr 00:22:64:2D:AD:37 Changing the HWADDR of ifcfg-eth1 to one below, didn't help: - # cat ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none HWADDR=00:22:64:2d:ad:36 ONBOOT=yes TYPE=Ethernet IPADDR=168.232.90.174 NETMASK=255.255.255.0 USERCTL=no PEERDNS=no IPV6INIT=no # service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Setting network parameters: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] Bringing up interface eth1: Device eth1 has different MAC address than expected, ignoring. [FAILED] Changing the HWADDR of ifcfg-eth1 to one up, didn't help, too: - # cat ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none HWADDR=00:22:64:2d:ad:38 ONBOOT=yes TYPE=Ethernet IPADDR=168.232.90.174 NETMASK=255.255.255.0 USERCTL=no PEERDNS=no IPV6INIT=no # service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Setting network parameters: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] Bringing up interface eth1: Device eth1 has different MAC address than expected, ignoring. [FAILED] These 2 are actually on board network interfaces, I'm not sure whether it was due to some updates that cause the driver not working anymore. But wonder how come eth0 can up and running without problem: - # find /lib/modules -name "tg*" /lib/modules/2.6.9-22.EL/kernel/drivers/net/tg3.ko /lib/modules/2.6.9-22.ELsmp/updates/tg3.ko # ls -l /lib/modules/2.6.9-22.EL/kernel/drivers/net/tg3.ko -rwxr--r-- 1 root root 133728 Sep 20 2005 /lib/modules/2.6.9-22.EL/kernel/drivers/net/tg3.ko # ls -l /lib/modules/2.6.9-22.ELsmp/updates/tg3.ko -r--r--r-- 1 root root 1042011 Jul 13 2010 /lib/modules/2.6.9-22.ELsmp/updates/tg3.ko |
Well I did a little google on your error.
It seems the solution of your problem is somewhere in kernel upgradation Well for now check the MAC address of eth1 with this command Code:
#ifconfig eth2 | awk '/HW/ {print $5}'I won't be able to help further and if you don't get a solution try asking some senior member whether it is due to kernel issue? Sorry :( |
Hi deep27ak, as eth1 is not up at all so there is no output and therefore unable to see the HWADDR.
Thank you for your help anyway...... Is there anyone that can give me some advise?? Thank you. |
I agree with deep27ak, sounds kernel/driver related...
If the servers not in production, can you reboot to a live cd with a newer/different kernel, and see if that detects both if's correctly? |
Hi fukawi1, this is a production server hosting Oracle database. I'm thinking to do a reboot next week,
I'm just worried that would eth0 also not working after reboot?? A bit scary cause there's no one good in Linux administration. I'm actually the DBA here...... |
For the time being if you want to check then try deleting the current eht1 configuration and recreating it
You can do that graphically Code:
#system-config-networkIf that doesn't affect your server |
Hi deep27ak, I tried deleting the eth1 and "service network restart" but it's not improving..
Thank you. |
Do you know for sure that the "other port" on your server is a real ethernet adapter? Could it be a kvm only interface? (I'm asking because our server has 2 gigabit ports and another dedicated to just some sort of virtual keyboard/monitor/mouse thing.)
