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 stack-unit-number port number portmode quad
• number: enter the port number of the 40G port to be split.
