interface breakout
Splits a front-panel Ethernet port into multiple breakout interfaces.
Syntax
interface breakout node/slot/port map {100g-1x | 50g-2x |40g-1x | 25g-4x |
10g-4x | 25g-4x}
Parameters
• node/slot/port — Enter the physical port information.
• 100g-1x — Reset a QSFP28 port to 100G speed.
• 50g-2x — Split a QSFP28 port into two 50GE interfaces.
• 40g-1x — Set a QSFP28 port to use with a QSFP+ 40GE transceiver.
• 25g-4x — Split a QSFP28 port into four 25GE interfaces.
• 10g-4x — Split a QSFP28 or QSFP+ port into four 10GE interfaces
Default Not configured
Command Mode 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.
