We have two FG6501F firewalls that we plan to upgrade to. We are testing our fiber cables to ensure we have link, prior to deployment. When connecting the QSFP28 100G fiber cables between the two FG6501F chassis we get link. However, when connecting from the 100G port on the new Firewall to a 100G port on a Cisco Leaf switch (In Cisco ACI) we do not get link. Has anyone experienced a similar issue? Any assistance is appreciated in resolving the issue.
They are SR optics. 7 meter 100G QSFP28
It is likely that you will need to manually set the interface forward-error-correction value on the FGT to rs-fec.
config system interface edit "port25" set forward-error-correction rs-fec set speed 100Gfull next end

I will configure the changes and see if that establishes link. Thanks.
