Splitting QSFP Ports to SFP+ Ports
The platform supports splitting a single 40G QSFP port into four 10G SFP+ ports using one of the
supported breakout cables (for a list of supported cables, refer to the Installation Guide or the Release
Notes ).
NOTE: When you split a 40G port (such as fo 1/4) into four 10G ports, the 40G interface
configuration is still available in the startup configuration when you save the running configuration
by using the write memory command. When a reload of the system occurs, the 40G interface
configuration is not applicable because the 40G ports are split into four 10G ports after the reload
operation. While the reload is in progress, you might see error messages when the configuration file
is being loaded. You can ignore these error messages. Similarly, such error messages are displayed
during a reload after you configure the four individual 10G ports to be stacked as a single 40G port.
To split a single 40G port into four 10G ports, use the following command.
• Split a single 40G port into four 10G ports.
CONFIGURATION mode

–
stack-unit
: enter the stack member unit identifier of the stack member to reset. The range is
from 0 to 11
–
number
: enter the port number of the 40G port to be split. The Z9000 range is from 0 to 31.
Important Points to Remember
• Splitting a 40G port into four 10G ports is supported on standalone and stacked units.
• You cannot use split ports as stack-link to stack a system.
To verify port splitting, use the
show system stack-unit 0 fanout {count | configure}
command.
• The quad port must be in a default configuration before you can split it into 4x10G ports. The 40G
port is lost in the configuration when the port is split; be sure that the port is also removed from other
L2/L3 feature configurations.
Converting a QSFP or QSFP+ Port to an SFP or SFP+ Port
You can convert a QSFP or QSFP+ port to an SFP or SFP+ port using the Quad to Small Form Factor
Pluggable Adapter (QSA).
QSA provides smooth connectivity between devices that use Quad Lane Ports (such as the 40 Gigabit
Ethernet adapters) and 10 Gigabit hardware that uses SFP+ based cabling. Using this adapter, you can
