Allow only supported FEC implementations on 10G, 25G, 40G, and 100G interfaces 7.0.4

Only supported FEC (forward error correction) implementations are allowed to be configured on 10G, 25G, 40G, and 100G interfaces based on the speed that is selected.

  • For 1000M, 10G, or 40G, FEC is not supported and the option is disabled.
  • For 25G and 100G, FEC is automatically set to cl91-rs-fec by default.

In the following examples, the interface speed is changed to various options to demonstrate how the FEC setting is affected.

Example 1: changing the speed from 25G to 1000M

To change the interface speed:
config system interface 
    edit port3
        set speed 1000full 
    next
end

The speed/mediatype/FEC of port3 will be changed from 25000full/sr/disable to 1000full/gmii/disable.
Do you want to continue? (y/n)y

Since the speed changed to 1000M, the forward-error-correction setting is automatically disabled and no longer available in the CLI.

Example 2: changing the speed from 40G to 100G

To change the interface speed:
config system interface 
    edit port26
        set speed 100Gfull 
    next
end

The speed/mediatype/FEC of port26 will be changed from 40000full/sr4/disable to 100Gfull/sr4/cl91-rs-fec.
Do you want to continue? (y/n) y

Since the speed changed to 1000G, the mediatype setting automatically changes to sr4, and the forward-error-correction setting automatically changes to cl91-rs-fec. When the speed was 40G, the forward-error-correction setting was disabled.

Example 3: changing the speed from 1000M to 25G

To change the interface speed:
config system interface 
    edit port3
        set speed 25000full  
    next
end

The speed/mediatype/FEC of port3 will be changed from 10000full/sr/disable to 25000full/sr/cl91-rs-fec.
Do you want to continue? (y/n)y

Since the speed changed to 25G, the forward-error-correction setting automatically changes to cl91-rs-fec. When the speed was 1000M, this setting was disabled.
