One thing I notice is the ARP outputs. It seems that the router is not getting arp replies. while the sw is completing ARP process.
Thanks

We solved this issue by upgrading IOS from 124-3 to 124-25g. The URL that Joseph posted was very helpful
Thanks,

Thanks for letting us know that you got it to work by changing versions. In the link that was posted it shows that 12.4(3) is too early a version to support EtherChannel.
I agree that the link Joseph posted is quite helpful and do not understand why someone gave it 2 stars. I think it deserves +5.
