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).

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.

To revert the port mode to 40G, use the no stack-unit stack-unit-number port port-number portmode

quad command.

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 stack-unit-number fanout {count | configure} command.
