Usage Guidelines
Use the rate-mode dedicated command to set the dedicated rate mode for the specified ports.
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 |
When you dedicate the bandwidth to one port, you must first administratively shut down the ports in the group, change the rate mode to dedicated, and then bring the dedicated port administratively up. |
Table 1 identifies the ports that are grouped together to share each 10 Gb/s of bandwidth and which port in the group can be dedicated to utilize the entire bandwidth.

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. |
When you enter the rate-mode dedicated command, the full bandwidth of 10 Gbps is dedicated to one port. When you dedicate the bandwidth, all subsequent commands for the port are for dedicated mode.
This command does not require a license.
Examples
This example shows how to configure the dedicated rate mode for Ethernet ports 4/17, 4/19, 4/21, and 4/23:
switch# configure terminal
switch(config)# interface ethernet 4/17, ethernet 4/19, ethernet 4/21, ethernet 4/23
switch(config-if)# shutdown
switch(config-if)# interface ethernet 4/17
switch(config-if)# rate-mode dedicated
switch(config-if)# no shutdown
