CONFIGURATION
Usage Information
  • Each breakout interface operates at the configured speed; for example, 10G, 25G, or 50G.
  • The no interface breakout node/slot/port command resets a port to its default speed: 40G or 100G.
  • To configure breakout interfaces on a unified port, use the mode {Eth | FC} command in Port-Group Configuration mode.
  • On the MX9116n Fabric Engine and MX5108n Ethernet switch, the backplane server-facing ports do not support the interface breakout command. In show inventory media output, the status category of the backplane ports is displayed as FIXED.
  • On the S4148U-ON platform, ensure that you use the same breakout mode as you have configured on the peer interface. For example, if you have explicitly configured the interface on the peer device as 10g-4x, use the same configuration on your switch.
Example 
OS10(config)# interface breakout 1/1/41 map 10g-4x
