As I see in cisco documentation
It'll be supported in future IOS releases
"Support for copper 1000BASE-T and fiber 100BASE-FX module will be added in future Cisco IOS® Software releases. An up to date list of supported transceivers can be found under "Cisco 10 Gigabit Ethernet Transceiver Modules Compatibility Matrix" and "Cisco Gigabit Ethernet Transceiver Modules Compatibility Matrix".
Anybody know when copper will be supported n what release)?
I'm interesting in GLC-T-CO model.
