rs – Reed-Solomon
fc – FireCode
none – no FEC applied.
By CLI:
admin@sonic:~$ sudo config interface speed Ethernet48 40000 admin@sonic:~$ sudo config interface speed Ethernet52 40000 admin@sonic:~$ sudo config reload -y
Check the status:
admin@sonic:~$ show interface status | grep 'Ethernet28\|Ethernet60' Ethernet28 101,102,103,104 40G 9100 rs Ethernet28 routed down up N/A N/A Ethernet60 69,70,71,72 40G 9100 rs Ethernet60 routed down up N/A N/A
By editing /etc/sonic/config_db.json file:
"PORT": {
....
"Ethernet28": {
"admin_status": "up",
"alias": "Ethernet28",
"autoneg": "1",
"fec": "rs",
"index": "7",
"lanes": "101,102,103,104",
"mtu": "9100",
"speed": "100000"
....
}
And reload the config by “admin@sonic:~$ sudo config reload -y”
This section shows a sample port configuration to enable forward error correction (FEC) mode in SONiC.
In Netberg SONiC, FEC is enabled by default on the interfaces.
FEC mode support three options:
rs – Reed-Solomon
fc – FireCode
none – no FEC applied.25G FEC recommendations
