Hello Experts,
I am looking to enable FEC on a 10G fiber link using Cisco 10GBASE-SR SFP+ transceiver and Cisco Catalyst 9500 switch. Is it possible to use FEC in this configuration? What commands to I need to issue to the switch to enable FEC? Thank You.

Hi
The command is as follow:
switch(config-if-range)# fec {auto | cl91 | off}
• auto—Enables the FEC feature based on the transceiver type.
• cl91—Enables clause 91 for 100 Gigabit interface.
• off—Disables FEC for the interface range.
But, if you look at the Data sheet, you are not going to find it:
Although on this link, they mention FEC for 9500.

Flavio,
Thanks for the reply. I have not been able to try this yet but I have some questions you may know the answer to.
Regarding this:
switch(config-if-range)# fec {auto | cl91 | off}
• auto—Enables the FEC feature based on the transceiver type.
• cl91—Enables clause 91 for 100 Gigabit interface.
• off—Disables FEC for the interface range.
What type of FEC is supported? (RSFEC, etc.)
What determines the FEC mode used when set to Auto?
Thank You.
