Channel Bonding Update
Just a quick update. If you do channel bonding on your ethernet, there apparently is really no good way to tell the speed of your interface. I tried mii-tool to see what the interface looked like, but I was horrified to see it reported 10bt half duplex on 2 bonded 100bt full duplex connections. After a half hour of googling, I was no closer to an answer although I have found many references to not paying attention to anything mii-tool says about it 😉
I use bonding on a day to day basis, this is what I put in /etc/modprobe.conf:
alias bond0 bonding
options bond0 mode=1 miimon=100
(or at least this is what I do to enable eth1 to be a hot standby in the even that either eth0 or the switch it is connected to go down), also, if you are bonding both ports to the same switch (for doubling up your bandwidth) then you want to change that mode= to the option that corresponds with that (options listed here: http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/ref-guide/s1-modules-ethernet.html#S3-MODULES-BONDING-DIRECTIVES )
Also, in your ifcfg-bond0 you may want to add:
GATEWAY=x.x.x.x
Hope that helps,
Karim
also, in your ifcfg-ethX files, you may want to add something to this effect as your last line:
ETHTOOL_OPTS=”speed 1000 duplex full autoneg on”
