Catalyst 9600 100Gbit/s FEC

[sstermann]

Hello everyone,

I have a cat9600 and would like to connect a Sonicwall with 100Gbit/s QSFPs.
But the 100Gbit/s ports remain notconnected.
As a test I have patched a loopback to test the function of the QSFPs. The test was successful from cat9600 to cat9600 and Sonicwall to Sonicwall.
Therefore I assume that I have to configure the FEC algorithm.
With the cat9500 I can execute the command fec cl74 in the interface. The cat9600 does not recognize the fec command. What can I do?
IOS-XE 17.12.05 advantage

Best regards
Sebastian

Hello @sstermann 

Try to configure fec CL74 on the SonicWall ?

That was also my first intention. But the Sonicwall admin wasn't able to do it either.
But it must be possible on the Cisco side.
