fec
Congures Forward Error Correction on 25G, 50G, and 100G interfaces.
Syntax
fec {CL74-FC | CL91-RS | CL108-RS | off}
Parameters
• CL74-FC — Supports 25G and 50G
• CL91-RS — Supports 100G
• CL108-RS — Supports 25G and 50G
• off — Disables FEC
Defaults
• For 25G and 50G interfaces: o
• For 100G interfaces: CL91-RS
Command Mode CONFIGURATION
Usage Information
The no version of this command resets the value to the default.
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# fec CL74-FC
Supported Releases 10.3.0E or later
interface breakout
Splits a front-panel Ethernet port into multiple breakout interfaces.
Syntax
interface breakout node/slot/port map {10g-4x | 25g-4x | 40g-1x | 50g-2x |
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
• Each breakout interface operates at the congured speed; for example, 10G, 25G, or 50G.
• The no version of the command resets a port to its default speed—40G or 100G.
• To congure breakout interfaces on a unied port, use the mode {Eth | FC} command in the Port-Group
Conguration mode.
Example
OS10(config)# interface breakout 1/1/7 map 10g-4x
