I want to bond for bandwidth. Here are my ifcfg-* files.


Here is my /etc/modprobe.conf file:

Does everything look correct? When I restart the network services or reboot this is what is in the /var/log/messages:

From my understanding for this type of bonding I do not have to do anything special to the switch ports so I have not. If I was going to be doing VLAN tagging then I would have to trunk the ports together. Is this correct?

Is the messages in the messages file normal or do I have something misconfigured?

Ok so I followed those instructions. This is the output from messages file when restarting the network service.

Couple problems from log file:
It shows an error with eth0 MAC still in use and wants me to change the MAC address of eth0. Is this necessary?

It shows enslaving eth0 and eth1 but it only states brining up eth0 in the bond. Is this a normal output for bonding 2 NIC's together for bandwidth?

"Oct 26 11:04:43 server1 kernel: bonding: bond0: Warning: the permanent HWaddr of eth0 - 00:00:00:00:00:00 - is still in use by bond0. Set the HWaddr of eth0 to a different address to avoid conflicts."

Wonder if the nic or driver can't support bonding?

Just my 2p....

this is my debian \etc\network\interfaces config and it's working with LACP through my switch


auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_miimon 100
bond_mode 802.3ad

auto vmbr0
iface vmbr0 inet static
address 192.168.1.253
netmask 255.255.255.0
gateway 192.168.1.254
dns-nameservers 192.168.1.1 8.8.8.8
dns-search home.mcnair.co.uk
bridge_ports bond0
bridge_stp off
bridge_fd 0

The last thing though, is this, 802.11d will, I believe only share the connection, it will not increase your bandwidth PER CONNECTION. so if you bond 2x1gbps interfaces the max throughput you will get through a single connection is 1gbps, but you could have 2x1gbps connections to the same address. I bonded so see what the max bandwidth I could get was from my 10 disk raid array, but this would still saturate the single connection I could get to the machine (if that makes sense).

regarding your error "permanent HWaddr of eth0 - 00:00:00:00:00:00 - is still in use by bond0". No network card should have a blank mac address afaik. Also, once you've created a bond, unless you bring it down properly bond0 will remain intact and you'll be reconfiguring it. I would recommend, if you can, doing a reboot (or maybe a /etc/init.d/networking restart at the very least) to ensure that bond0 is destroyed across reconfiguration attempts

have already rebooted and restarted the network service. How can I test if the bond is working?

Pull the plug on one of them or wireshare the data.
Depending one the setup, you might notice more bandwidth. I doubt it as most other parts are slower than the bond.

mii-tool should tell you....as would looking at ifconfig -a as would looking at the end of syslog as would pulling the network cable out of one.

regarding This page will tell you what number you need in there

yeah thx figured that one out. I am using mode=6 so I did not have to make any changes on the switch.
