Solved!
Go to SolutionPowerConnect 6248 and Broadcom NIC Teaming
I have a few PowerEdge servers with Broadcom 57xx nics that are configured for teaming (802.3ad LACP). I've noticed that i am getting packet loss on the these servers that this was done on. There are no LAG groups assigned to any ports on the switch. Is this even needed to make this work properly? If so can someone walk me though the proper switch configuration to make this work.
Thanks in advance.
Thanks for the reply Thilo. I made the change on one of the servers. I was able to pull one of the cables and maintain connectivity. Also, i have not seen any further packet loss since making the change. I just want to confirm with you that when i make the changes for the other servers that have NIC teaming, i increment the port-channel command by 1, correct? So in essence, the command for "server b" would be "channel-group 2 mode auto" for both of the interfaces.
Thanks again for your assistance.

try this:
interface ethernet 1/g43
channel-group 1 mode auto
description 'Server eth0'
exit
!
interface ethernet 1/g44
channel-group 1 mode auto
description 'Server eth1'
exit
!
interface port-channel 1
description 'Server'
exit
------------------------
"channel-group 1 mode auto" configures LACP
After configuring it this way you should pull out one cable and check if is still up and running. Then with the other cable as well.
