Important Points to Remember
• For 10–Gigabit and 40–Gigabit Ethernet interfaces, FEC configurations are not applicable.
• 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 first. 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.
• To view CR4 auto-negotiation and FEC configurations for 25–Gigabit, 50–Gigabit and 100–Gigabit Ethernet interfaces, use the show
interfaces command.
