PowerConnect 2724 + Link Aggregation +CentOS
Has anyone been able to make this work in 802.3ad mode?
We can make it work in the default round robin mode.
The hardware is a four year old Supermicro X5DPA-GG. That's a dual Xeon server with integrated Dual Gigabit NIC (Intel 82541) :

/proc/net/bonding/bond0 claims all links are up and everything is happy. However I do get this message in syslog whenever the bond is initialized:
bonding: An illegal loopback occurred on adapter ethX
It will switch between eth0 and eth1. All I can find is the c code for it and this message appears to be a kernel error when its doing a MAC comparison. I don't know if you guys experienced that as well.
Regardless here is the sysconfig stuff i have been using which may help you:
# /etc/modprobe.conf setup
cat >> /etc/modprobe.conf
install bond0 modprobe bonding --ignore-install -o bond0 miimon=100 mode=4
# /etc/sysconfig/network-scripts/ifcfg-eth0 & ifcfg-eth1
DEVICE=ethX # where X = id of the current adapter
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
# /etc/sysconfig/network-scripts/
DEVICE=bond0
USERCTL=no
ONBOOT=yes
