Hi According to Cisco documentation Cat4500 with SupV is providing 6Gbps per one slot. It this 6Gbps is full-duplex or half-duplex. I mean if half-duplex then we have 1:2 oversubscription for 6xGE card (6gb full-duplex=12gbps half duplex). And what about Cat6500 and Sup32 ? How much Gbps per slot and half-duplex or full-duplex ? Thanks Robert
