Yes, I'm running LACP between SUP-720 6500s and BIG-IP 6900 boxes on
the SFP interfaces.  The key was to disable ethernet flow control on
the BIG-IP side.  They enable it by default and it really confuses the
Cisco side.

After disabling flow control on the BIG-IP's physical interfaces, LACP
came up just fine.
