Fortigate 601F ==> Fortiswitch 2048F ==> Fortiswitch 648F
- Check the phy-mode on the Fortiswitch-2048F ports to make sure 10G/25G are used on them (this is when connecting to either FortiGate or FortiSwitch).
FortiSwitch CLI:
config switch phy-mode
set port1-port12-phy-mode 25G
set port13-port24-phy-mode 1G/10G
set port25-port36-phy-mode 25G
set port37-port48-phy-mode 25G
end
- Disable the FEC-state when connecting FortiSwitch-2048F to FortiSwitch-648F:
Fortiswitch CLI:
config switch physical-port
edit port3
set fec-state disabled
show
end
FortiGate switch-controller CLI:
config switch-controller managed-switch
edit <FSW SN>
config ports
edit port3
set fec-state disabled
show
end
Check:
diagnose switch physical-ports list port3
- FortiGate-601F 10G-25G ULL ports change (x5,x6,x7,x8 ports of the FortiGate-601F can either be set to 10G/25G).
FortiGate CLI:
config system npu
set ull-port-mode 10G or 25G
end
FortiGate will do a reboot after this change and once it comes back, the ports of the FortiGate will either have 10G or 25G speed set on them.
After these changes, the FortiSwitch-2048F links will connect to the FortiGate-601F and FortiSwitch-648F.
