If you need to change the default port speed and/or breakout configuration of an uplink port, you must complete this task before creating the uplink.
For example, the QSFP28 interfaces that belong to port groups 13, 14, 15, and 16 on MX9116n FSE are typically used for uplink connections. By default, the ports are set to 1x 100 GbE. The QSFP28 interface supports the following Ethernet breakout configurations:
- 1x 100 GbE – One 100 GbE interface
- 1x 40 GbE – One 40 GbE interface
- 2x 50 GbE – Breakout a QSFP28 port into two 50 GbE interfaces
- 4x 25 GbE – Breakout a QSFP28 port into four 25 GbE interfaces
- 4x 10 GbE – Breakout a QSFP28 port into four 10 GbE interfaces
The MX9116n FSE also supports fibre channel (FC) capabilities using universal ports on port-groups 15 and 16. For more information about configuring FC storage on the MX9116n FSE, see Scenario 5 and Scenario 6 in the Configuration scenarios section.
For more information on interface breakouts, find the relevant version of the User Guide in the OME-M and OS10 compatibility and documentation table.
