Oracle Enterprise Linux 5.3 NIC bonding on a Dell PE2950/PER 900
Dear All,
I did the Configuration NIC Teaming (bonding) Oracle Enterprise Linux 5.3 on a Dell PE2950 and PE R900 Machine, The configuration Details are given below /etc/sysconfig/netword-scripts/ifcfg-bond0 DEVICE=bond0 USERCTL=no ONBOOT=yes BROADCAST=10.x.y.255 NETWORK=10.x.y.0 NETMASK=255.255.255.0 GATEWAY=10.x.y.1 IPADDR=10.x.y.65 /etc/sysconfig/netword-scripts/ifcfg-eth0 DEVICE=eth0 USERCTL=no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none /etc/sysconfig/netword-scripts/ifcfg-eth1 DEVICE=eth1 USERCTL=no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none /etc/modprobe.conf alias eth0 bnx2 alias eth1 bnx2 alias scsi_hostadapter megaraid_sas alias scsi_hostadapter1 ata_piix alias scsi_hostadapter2 qla2xxx alias peth0 bnx2 alias bond0 bonding options bonding miimon=100 mode=0 after the configuration, when I restart the Network service, the following Messages are displays service network restart Shutting down interface bond0: bonding: bond0: Warning: the permanent HWaddr of eth0 - 00:24:E8:5E:8F:F3 - is still in use by bond0. Set the HWaddr of eth0 to a different address to avoid conflicts. [ OK ] Shutting down interface eth0: bonding: bond0: Unable to update slaves because interface is down. [ OK ] Shutting down loopback interface: [ OK ] Disabling IPv4 packet forwarding: net.ipv4.ip_forward = 0 [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface bond0: bonding: bond0: Warning: failed to get speed and duplex from eth0, assumed to be 100Mb/sec and Full. [ OK ] please give me a solution how to solve this issue; Thank you in advance Best Regards, Salam |
I seem to remember that things worked better when we ending ethernet bonding before restarting the network. I am looking for those notes and will update later.
After restarting networking with the warnings you posted, what do you see in the routing table? What do you see with the command `ethtool bond0`? |
Routing table and Ethtool
Dear wfh,
Thank you for your reply when i enter the ethtool and Routting tables are given belwo # ethtool bond0 Settings for bond0: No data available # netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.17.40.0 0.0.0.0 255.255.255.0 U 0 0 0 bond0 192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 bond0 0.0.0.0 172.17.40.254 0.0.0.0 UG 0 0 0 bond0 please update me , what i have to do to avoid the warning message. both NIC s are bnx2 Gigabite, if we are bonding the Gigabite NICs, is the speed will be the same as 1000 or 100 mbps ? Regards, Salam |

Let me also refer you to Bugzilla for Redhat. This is related:
https://bugzilla.redhat.com/show_bug.cgi?id=241719 I remember testing ethernet bonding on Cyclades devices. Our programmers, as I remember, put in a fix which either spoofed the MAC (I think they took the MAC of eth0 and make it the default machine address regardless of the active interface's real address). There are issues with this. Not sure what to tell you. |
