I need to connect 6 nic to a single bond, while 2 of the nics are Broadcom and the other 4 are Intel, on RHEL5.4.
Two questions please:
1. Is this configuration possible and what are prerequisites/configuration on the switch and the nics?
2. After configuring this bond, When looking in /proc/net/bonding/bond0(below) we see the 6 eth devices in their bond. However only two of them have the aggregator ID and it only shows two ports because of this. What does this mean? Is it normal?

You are most-likely hitting an upstream regression that crept into RHEL5.4.
