For these multi-mode SFP interfaces, SerDes is the default mode. You can use a
CLI command to change the interface to operate in SGMII mode.
Depending on the type of transceivers you install, you need to configure the
FortiGate unit or module for the transceiver using the CLI. Use the mediatype
keyword of the config system interface CLI command to change the
interfaces to either SerDes or SGMII mode.
To change the media type for the proper transceiver, enter the following CLI
command:
config system interface
edit <interface_number>
set mediatype <sgmii | serdes>
end
For example:
config system interface
edit AMC-SW1/1
set mediatype sgmii
set speed auto
next
edit AMC-SW1/2
set mediatype sgmii
set speed auto
end
Configure the speed
You must also ensure the speed for the interface is correct for the installed
transceiver. Forcing the speed could result in link failure and disrupted service.
Fortinet recommends enabling link speed auto negotiation by setting speed to
auto.
Use the following command to configure the auto speed setting:
config system interface
edit AMC-SW1/1
set speed auto
end
