In the previous example, several ports display “Auto” in the Speed field. In the following example, the speed of port 1/1 is set to 100Mb and
then its auto-negotiation is disabled.

Syslog Warning Upon Connecting SFP28 Optics
with QSA
When you connect the SFP28 optics with the QSA, the system displays the following syslog warning:
For Dell-qualified SFP28 optics:
Aug 8 20:31:56 %Z9100-ON:1 %IFAGT-5-INSERT_OPTICS_SFP28: Optics SFP28 inserted in slot 1 port
7/1. Wrong QSA in use. Please utilize QSA28, not lower speed QSA to guarantee support and
performance for 25G Optics and cables
For non Dell-qualified SFP28 optics:
Aug 8 20:31:56 %Z9100-ON:1 %IFAGT-5-UNSUP_OPTICS: Non-qualified optics in slot 1 port 7/1.
Wrong QSA in use. Please utilize QSA28, not lower speed QSA to guarantee support and
performance for 25G Optics and cables
FEC Configuration
FEC configurations are available on 100–Gigbit, 50–Gigabit and 25–Gigabit Ethernet interfaces.
To configure FEC, use the following commands.
Enable FEC.
INTERFACE mode
fec enable
The CL91 keyword enables RS-FEC on 100G interfaces as per IEEE. The system displays an error message when this is applied on
25G or 50G interfaces.
The CL74 keyword enables BaseR-FEC on 25G or 50G interfaces as per 25G/50G Ethernet Consortium. The system displays an error
message when this is applied on 100G interfaces.
The CL108 keyword enables RS-FEC for single 25G lane as per IEEE 802.3by. The system displays an error message when this is
applied on 100G interfaces.
To disable FEC, use the no fec enable command.
Set to default FEC value.
INTERFACE mode
fec default
