Hi,

Have you configured the port as switchport mode fex-fabric? The FET-10G only works for this mode.

    Do the peer links have special cables ?   Is it possible the fex's use this specific gbic and cannot be used as a peerlink connection ?

    Yeah it appears these are for  fex connections only.  Just found out we have special twinax cables coming for the peer link connections.  Thanks for the info.

Apart from switchport mode fex-fabric, make sure you enable feature fex.
