Cat 6500 Etherchannel problem b/w gbic 6516 and 6548

We couldnt successfully create a two port UTP ether channel between two Cat 6500 switches with Switch 1 having ws-x6516-gbic with ws-g5483 gigabit connector and Switch 2 having ws-x6548-ge-tx.

The error message was: %EC-SP-5-DONTBNDL: Gi7/3 suspended: incompatible partner port with Gi7/1

we are 100% sure that all ports are having exactly the same configuration.

The problem was resolved when we changed the module on Switch 1 to ws-x6408-gbic.

Can anyone explain why was the port channel unable to form between ws-x6516-gbic module and ws-x6548-ge-tx module.

You might want to check the default STP port cost; each port must have the same cost.

Please post the switch port configs. Also " Show version " and show module from the switch.
