Problem with Etherchannel
I'm trying to configure Etherchannel on AIX 5.3 and I'm having some problems. I am aggregating both of the onboard NIC's (ent0 and ent1) into a new adapter ent2 for failover reasons obviously. At first I was experiencing a problem where about 50% of all my packets would be dropped. Then after removing all the network devices and rediscovering and recreating the aggregate, it is much better but I am still losing about 1-2% of the packets.
I am assured that there is no problems with the switch configuration, and I have verified that both network cables are working properly.
I'm hoping that someone will point out something that I have missed in created the aggregate.

Hello,
POWER7 machine.
4 x 1Gbit port ethernet adapter is dedicated to vios. 8023ad etherchannel is created using those 4 ports. Etherchannel adapter is shared to lpars using SEA.

aggregate-ios <source_config >optimised_config
DESCRIPTION
Takes cisco IOS configuration on stdin, and optimises any prefix filters found using aggregate(1). Optimised filters are produced on std-
