Usage Information
This command is not applicable for 10–Gigabit and 40–Gigabit Ethernet interfaces.
For 100-Gigabit Ethernet interfaces, CR4 auto-negotiation is enabled by default. You cannot enable or disable FEC
separately. To enable or disable FEC, disable CR4 auto-negotiation rst. Similarly, CR4 auto-negotiation cannot be
enabled if FEC is already enabled or disabled. To enable CR4 auto-negotiation, set to default FEC value using the
fec default command.
For 25–Gigabit and 50–Gigabit Ethernet interfaces, FEC is disabled by default. You can enable or disable FEC and
CR4 auto-negotiation simultaneously.
Related Commands fec default — sets the FEC to default value.show cong — displays the interface conguration.
