fec
Congures Forward Error Correction on 25G and 100G interfaces.
Syntax
fec {CL74-FC | CL91-RS | CL108-RS | off}
Parameters
• CL74-FC — Supports 25G
• CL91-RS — Supports 100G
• CL108-RS — Supports 25G
• off — Disables FEC
Defaults
• For 25G interfaces: off
• 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 1/1/41
OS10(conf-if-eth1/1/41)# fec CL91-RS
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 {100g-1x | 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.
• 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 congured
Command Mode CONFIGURATION
Usage Information
• Each breakout interface operates at the congured speed; for example, 10G or 25G.
• The no interface breakout node/slot/port command resets a port to its default speed: 40G or
100G.
