The Cisco Nexus 3064-X is compatible with existing Gigabit Ethernet infrastructures. The 10 Gigabit Ethernet interfaces can operate in either Gigabit Ethernet or 100-Mbps mode. Table 3 lists the Gigabit Ethernet SFP transceivers that are supported. 100-Mbps connectivity can be achieved by using copper-based SFP transceivers (SFP-GE-T and GLC-T).
