    Hi All,
    I'm doing a downgrade from 6509 to 4510, one issue i'm facing now is my LACP in 4510 keep causing my physical link to be suspend! the same configuration works in 6509 switch, although in 6509 the logical interface is down but at least the physical interface is up. in 4510 logical is down, physical is suspend and down as well. OMG... how to solve this?

    and i get this log on 4510
    May 14 00:54:57.759: %EC-5-L3DONTBNDL2: Gi10/24 suspended: LACP currently not enabled on the remote port.
    May 14 00:54:58.659: %EC-5-L3DONTBNDL2: Gi10/23 suspended: LACP currently not enabled on the remote port.

    below my config for 6509 vs 4510
