Does anybody have an example of configuration for 1Gb/s.

Thanks

You didn't say what mode you want to work in. For active-backup mode with 2 network cards, static IP:

/etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
BOOTPROTO=static
NETMASK=x.x.x.x
ONBOOT=yes
TYPE=Ethernet
IPADDR=x.x.x.x

/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes

/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes

/etc/modprobe.conf
alias bond0 bonding
options bonding miimon=100 mode=active-backup

Hi There,
I have done the same exact configuration as yours but I want to force the link to be 1Gb/s with autoneg off.
Do you know how to do that?

Thanks again.

Shalom,

Auto negotiation should be on for all GB NIC cards.

Whats missing is you also need some card specific configuration in /etc/modprobe.conf

alias bond0 bonding
# options bond0 miimon=200 mode=active-active
options bond0 miimon=200 mode=0
alias eth0 e1000
alias eth1 e1000
alias eth2 tg3
alias scsi_hostadapter ata_piix
alias usb-controller ehci-hcd

That works for Intel.

You need to replace tg3 for broadcom and not try active active because it won't work with broadcom.

I think you need to change the Type=Ethernet in cfg-bond0 to Type=Bonding and include the Type=Ethernet in the other two ETHs.
