Rate Mode

On a 32-port 10-Gigabit Ethernet module, each set of four ports can handle 10 gigabits per second (Gb/s)
of bandwidth. You can use the rate-mode parameter to dedicate that bandwidth to the first port in the set
of four ports or share the bandwidth across all four ports.

Note All ports in each port group must be part of the same virtual device context (VDC). For more information
on VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release
5.x.

Speed Mode and Duplex Mode

The speed mode and duplex mode are interrelated for each Ethernet and management interface. By
default, each of these interfaces autonegotiates its speed and duplex mode with the other interface, but
you can change these settings. If you change the settings, be sure to use the same speed and duplex mode
setting on both interfaces, or use autonegotiation for at least one of the interfaces.
