100g-1x}
Parameters
• 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 for use with a QSFP+ 40GE transceiver.
• 50g-2x — Split a QSFP28 port into two 50G interfaces.
• 100g-1x — Reset a QSFP28 port to 100G speed.
Default Not congured
Command Mode CONFIGURATION
Usage Information Breakout mode operates at the interface line rate. Commit the breakout conguration immediately for changes to
take eect. The no interface breakout command resets a port to its default speed—40G or 100G.
