View Ethernet unified port interface OS10(config)# interface ethernet 1/1/41 OS10(conf-if-eth1/1/41:1)# show configuration ! interface ethernet1/1/41:1 no shutdown Configure breakout mode Using a supported breakout cable, you can split a 40GE QSFP+ or 100GE QSFP28 Ethernet port into separate breakout interfaces. All breakout interfaces have the same speed. You can set a QSFP28 port to operate in 40GE mode with a QSFP+ transceiver. interface breakout node/slot/port map {10g-4x | 25g-4x | 40g-1x | 50g-2x | 100g-1x} • node/slot/port - Enter the physical port information. • 10g-4x - Split a QSFP28 or QSFP+ port into four 10G interfaces. • 25g-4x - Split a QSFP28 port into four 25G interfaces. • 40g-1x - Set a QSFP28 port to use with a QSFP+ 40G transceiver. • 50g-2x - Split a QSFP28 port into two 50G interfaces. • 100g-1x - Reset a QSFP28 port to 100G speed. To configure an Ethernet breakout interface, use the interface ethernet node/slot/port:subport command in CONFIGURATION mode. Each breakout interface operates at the configured speed. Use the no version of the interface breakout command to reset 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.

The port autoconfigures breakout interfaces for media type and speed. For example, if you plug a 40G direct attach cable (DAC) with 4x10G far-side transceivers into a QSFP28 port, the port autoconfigures in 10g-4x Interface-breakout mode. RJ-45 ports and ports that are members of a port group do not support breakout auto-configuration. Breakout auto-configuration is disabled by default. Interfaces 99
